Answer:
It shows how violent the situation was and how scared Enrique was.
Explanation:
The book "Enrique's Journey" by Sonia Nazario tells the true story of a young boy named Enrique on his quest to find his mother who has gone to America in search of work. The story delves into the dangerous and menacing obstacles that migrants like Enrique had to endure and go through to get to the safer land in America. This story is also like an insight into the borderlands that is between America and the South American nations, with migrants coming in masses in the hope of a better and peaceful future.
As seen in the excerpt from the book, the author provides a scene where gangsters threaten and even assault anyone who went as far as to help the authorities identify them. This very act of torturing or using violent means to keep people quiet shows how dangerous life is for the migrants while trying to get to the other side. The characterization in this passage shows the violent scene that migrants have to endure and the emotional fear that people like Enrique were put in.
Answer:
It shows how violent the situation was and how scared Enrique was.

Answer:
2. The lime water turns milky in colour
3. To act as filters
4. To enable easy penetration of the root of planted crops.
See detailed explanation below
Explanation:
2. Our exhaled air principally contains carbon dioxide gas (CO2), which reacts with like water to produce a milky solution. The lime water is a solution of Calcium hydroxide (CaOH2), which chemically reacts with the C02 content of our exhaled air to form a compound called Calcium carbonate (CaCO3). Calcium carbonate is a whitish compound that appears chalky/milky.
3. Our nostrils contain a cavity called nasal cavity, which is lined with mucus (a viscous substance). The mucus helps to keep the nasal cavity wet. The hair in the nostrils also help prevent large particles in inhaled air from entering into the nasal cavity. The hair and mucus works together to filter out shirts and germs like bacteria etc from entering into the lungs.
4. Farmers loosen the soil which they plant their crops by mixing the layers of the soil. Loosening the soil encourages or promotes a deep and easier penetration of the plant roots. It also helps the soil to be properly drained and aerated i.e. penetration of water and air into the soil respectively.

Which sustainable practice is paired correctly with its impact on the environment? Using bamboo results in an increased use of forest trees. Practicing contour plowing results in a need for more land. Setting irrigation systems to run longer results in a reduction of water use. Building more wind farms results in a reduction of fossil fuel use.
Hey there! I'm happy to help!
Using bamboo results in an increased use of forest trees. Bamboo is a grass, not a tree. I don't see how using more bamboo would increase your usage of trees. This option is incorrect.
Contour plowing is when your plow around the contour lines (which are basically like elevation lines) of a hill or slope. This actually reduces soil erosion and lasting effects of natural storms and disasters, so it does not result in a need for more land. This option is incorrect.
Setting irrigation systems to run longer results in a reduction of water use. Irrigation is a system of watering, so you need water for it. It would not reduce water use. This option is incorrect.
Building more wind farms results in a reduction of fossil fuel use. If you are getting your power from renewable resources like the wind or the sun, you will not need to use as many fossil fuels, and this would reduce their use. This option is correct.
Have a wonderful day!
The practices that aid in economic, human and ecological dynamism and health is called sustainable practices. This procedure helps in conservatively preserving the limited sources.
The correct pairing is:
Option D. Constructing more wind farms results in a decrease in fossil fuel usage.
The practices can be explained as:
Using too many bamboos will result in the degradation of lands and increased soil erosion. It will not affect the usage of other forest trees.The method of agriculture practice in which the ploughing is done near the contour lines is called contour ploughing and does not need much land also helps in reducing soil erosion and disasters.The irrigation system conserves water and is a beneficial technique of watering the agricultural lands with an efficient amount of water.Wind energy generates more energy and power which is a renewable source compared to fossil fuels and reduces the use of petrol, diesel and coal.Therefore, option D is correct.

Thylakoids contain clusters of chlorophyll and proteins known as . They absorb sunlight and generate high-energy that pass along the .
Answer:
1) Photosystems
2) Thylakoid membrane
Explanation:
Photosynthesis is an important phenomenon for the cells of autotrophic organisms like green plants. It is the process through which they obtain their energy source. Photosynthesis, which consists of two stages, occurs in the Chloroplast of the cell.
The light dependent stage occurs in the thylakoid lumen of the CHLOROPLAST while the light independent stage occurs in the stroma. The thylakoid is a membrane-bound sac usually organized in stacks called GRANA.
The Chlorophyll pigment, which captures the photon of light needed for the photosynthetic process, is contained in the thylakoid. Also, embedded in the thylakoid space are protein complexes called PHOTOSYSTEMS, which are involved in the capturing photons of light and transferring of electrons. The Photosystems 1&2 are the functional units of photosynthesis.
The high energy generated by the Photosystems are transferred from one electron carrier to another along the thylakoid membrane in order to generate ATP and NADPH. This process is called Electron transport chain.
Thylakoids are the membrane-bound structures present within chloroplasts of the plant cell. Thylakoids consist of photosystems and are surrounded by the thylakoid membrane.
The correct blanks for the given statement are:
Thylakoids contain clusters of chlorophyll and proteins known as photosystems. They absorb sunlight and generate high energy that passes along the thylakoid membrane.
Photosystems in the thylakoids are the structural and functional protein complexes, which play a crucial role in performing photosynthesis. These systems are present along the thylakoid membranes, and carry out the primary photochemistry of photosynthesis.
The thylakoid membrane is involved in the light-dependent reactions of photosynthesis. The membrane absorbs light energy and is then converted into chemical energy. The high-energy generated is passed along the thylakoid membrane.
Therefore, the correct answers are photosystems and thylakoid membrane.

Transposable elements (TE)
Explanation:
A transposon, also known as 'jumping genes', is a particular sequence of DNA that can relocate inside of the genome. It affects the genetic identity and can be made use of to either reverse a mutation or create one - it duplicates that genetic sequence. Retrotransposons is a class of TE found in viruses.
I heard that mitochondria increase if we exercising. So, if i was exercising and suddenly stop exercising. Will the number of mitochondria same, and more food neededbfor energy and more energy not use and more fats produce?
Will i produce more fats when i stop exercising than when i never do exercise?
Please answer with the explanation
Answer:
I believe the amount of mitochondria in our body only increases after long term exercising.
When you are exercising, you do not produce more mitochondria straight away. Even after you stop, the amount of mitochondria will be the same.
I believe the production of mitochondria and the improvement of your muscles is the same. You need to exercise for awhile before you can get more mitochondria in your body.
As for your amount of food needed, it is not according to the amount of mitochondria you have. It is according to how much energy you need.
You should be able to tell how much food you need. So, you actually wont produce more fats. As long as you eat the correct and moderate amount of food.
You will not produce more fat when you stop exercising than when you never exercise. Like I said, the amount of fat produced is according to your food intake. Your food intake is according to your energy needs. As long as you eat moderately, you will not produce more fat. In fact, you will be able to burn fats better after long term exercise because your body will be healthier and able to moderate itself.

B) inheritance of acquired characteristics
C) change in response to need
D) a process of constant improvement, leading eventually to perfection
E) survival of the fastest
Answer:
The correct answer is - option A. differential reproductive success based on inherited traits
Explanation:
Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.
The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.
Thus, the correct answer is - option A. differential reproductive success based on inherited traits
Due to genetic changes and the environmental conditions when the organism adapts itself to the current situation for survival is called natural selection.
Natural selection means that the organism that survived over another have better traits and characteristics for adaptation.
The correct answer is:
Option A. differential reproductive success based on inherited traits.
This can be explained as:
A particular type of trait carried by an organism that is better for adapting to survival than the other organism carrying less favorable trait will have a better chance of survival and their reproductive success will be much higher.Based on the inherited characteristics the natural selection will be based on reproductive success.Differential reproductive success is an analysis in which comparison is done among the organism that survived and those that did not.Comparing their traits and characters can give an idea about the factor affecting the selection.Therefore, differential reproductive success based on inherited traits best expresses natural selection.

1. Histoplasma capsulatum is an endemic fungus that prefers sols erwiched with bal guano, whereas Aspergillus furgatus is a ubiquitous soll langus.
2. Individuals are not as routinely vaccinated against Aspergillosis as compared to Histoplasmosis
3. Histoplasma capsulatum is an opportunistic fungal pathogen affecting immunocompromised individuals, whereas Aspergillus fumigatus is a true fungal pathogen affecting both healthy and immunocompromised individuals.
4. The arthropod vector that carries Histoplasma capsulatum is only found in the Ohio and Mississippi valley regions, whereas the arthropod vector that carries Aspergillus fumigatus is found in many geographical locations.
Answer:
3. Histoplasma capsulatum is an opportunistic fungal pathogen that affects immunocompromised individuals, while Aspergillus fumigatus is a true fungal pathogen that affects both healthy and immunocompromised individuals.
Explanation:
Histoplasmosis is an oprtounista mycosis, that is to say that it increases in number in our organism occasionally generating infectious and non-protective pathology like the commensal flora.
Histoplasmosis respects American geographic limits and is because it lives in tropical and freshwater climates.
Histoplasmosis pathology is triggered if the person has a deficit in the immune response and if the risk of living or transiting the endemic area is corrected.
On the other hand, the aspergillus fungus is a fungus that enters the inhalation routes in a sporulated form and developed in the lungs, generating a high fatal risk, since it triggers inflammatory and necrotic symptoms in the lung, regardless of whether the person is immunodeficient or not. ... There were people who were shaved by this fungus and even selected hypersensitivity pictures, that is, the opposite of an immunodeficiency.
The Fungi of the Aspirgillus group do not discriminate against age, immune status, or other factors ... only inhalation of the spore is required to develop the pathological picture.

Answer:
Biotic factors and abiotic factors, plant and light energy, herbivores, heterotrophs, omnivores, carnivores, primary consumer, decomposers and tertiary consumers.
Explanation:
Both biotic and abiotic factors are interacting with each other in an ecosystem. Plants use light energy from the sun to produce their own food. Herbivores are the organisms that feed on producers (plants). Heterotrophs are those organisms which are unable to make their own food. Omnivores are the organisms that eat both plants and animals. Carnivores feed on animals only. Primary consumers are the consumer which feed on plants. Decomposers helps in the breakdown of dead bodies of plants and animals. Tertiary consumers feed on secondary consumer.
Place the steps of biofilm formation in the correct order: 1. Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably. 2. Surface (substratum) is preconditioned by environmental molecules. 3. Biofilm matures and some microorganisms escape to the planktonic state. 4. Microbes attach and detach from the preconditioned surface.
Answer:Step order:
2. The surface (substrate) is preconditioned by environmental molecules.
4.Microbes bind and detach from the preconditioned surface.
1.Quorum detection and extracellular matrix establishment begins as microbes bind more stably.
3. The mature biofilm and some microorganisms escape the planktonic state.
Explanation:
The biofilm is a highly complex structure where many microorganisms coexist, compete, reproduce, feed, within a micro-system with many ideal conditions for each microorganism that is housed in it.
The biofilm is resistant to non-selective antimicrobials, that is, to disinfectants such as sodium hypochlorite, chlorhexidine, among others.
Evidence was also presented that they are resistant to selective antimicrobials such as antibiotics, that is why they have great virulence factors or potential to trigger pathology.
The solution to destroy a biofilm is mechanical sweeping, with brushing as it happens on our teeth or even with the catheter cleaning brushes that are used (in addition to the sterilization methods).
This biofilm presents separate colonies in its interim with a fluid that it travels transmitting signals, food, toxins, resistant factors between these different types of microorganisms. This fluid and this communication between them is called quorum sensing and not all microorganisms tolerate it.
Many microorganisms compete with each other for the medium, an example is streptococcus mutating in the dental biofilm, which generates an acidic medium by metabolizing carbohydrates within the biofilm, thus generating that those bacteria that live in neutral or alkaline ph cannot reproduce and die.
The biofilm can be contained by bacteria, viruses, fungi and even parasites, but what they all have in common is that they have the ability to reproduce on an inert surface such as catheters, dental surfaces, silicone hoses.

What are digestive enzymes? Give three examples of digestive enzymes and briefly describe their specific functions.
Answer:
Digestive enzymes are the natural substances our body needs to help break down and digest food
We have three main digestive enzymes :
Proteases: These enzymes break down protein into small peptides and amino acids.
Lipases: break down fat into three fatty acids plus a glycerol molecule.
Amylases: Are responsible for breaking down carbs like starch into simple sugars.
Explanation:
Digestive enzymes are proteins that catalyze mainly hydrolysis reactions that make nutrients absorbable in the digestive tract. Pepsin is a gastric enzyme that turns proteins into albumoses and peptones which are shorter peptide chains that are then hydrolyzed to even shorter chains until amino acids by intestinal enzymes. Pancreatic amylase is an enzyme that turns starch(a polysaccharide) into maltose(a disaccharide). Lipase is present in the gastric juice, the pancreatic juice, and the intestinal juice. This enzyme catalyzes the hydrolysis of lipids(mainly triglycerides) into fatty acids and glycerol. When incomplete hydrolysis occurs triglycerides can become monoglycerides.
