Answer:B
Explanation:
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.

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 of the following best expresses the concept of natural selection?
A) differential reproductive success based on inherited traits
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.

A diploid human cell normally has 23 pairs of homologous chromosomes, but as a woman ages, the chances of nondisjunction increase. Imagine that a gamete is produced that received two copies of chromosome 21 due to nondisjunction during meiosis II. If the gamete is fertilized with a normal sperm, the embryo's cells will contain _______ chromosomes.
47 chromosomes instead of 46 because there are 3 chromosomes in pair 21. This is called Down syndrome, described most recently by Lejune in 1958
If the gamete is fertilized with a normal sperm, the embryo's cells will contain 47 chromosomes. The correct option is B.
What is nondisjunction?Nondisjunction refers to the phenomenon of unequal separation in meiosis.
If a haploid gamete has a missing chromosome due to nondisjunction, the diploid zygote it forms with another gamete will have only one copy of that chromosome from the other parent, a condition known as monosomy.
Nondisjunction occurs when the separation fails, causing both sister chromatids or homologous chromosomes to be drawn to one pole of the cell.
Mitotic nondisjunction can occur when topoisomerase II, condensin, or separase are inactivated.
Because pair 21 contains three chromosomes, there are 47 chromosomes rather than 46.
Thus, the correct option is B.

Which of the following statements are true? Multiple Choice Muscles work in antagonistic pairs because if one muscle pushes during contraction, the opposing muscle across the joint must pull. Muscles work in antagonistic pairs because muscles lengthen during contraction. Muscles work in antagonistic pairs because tendons lengthen during contraction. Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax.
Answer
if one muscle shorten during contraction the opposing muscle across the joint must relax
The true statement among the statements above is that Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax.
For better understanding, we have to know why muscle works in antagonistic pair and the reason for this pairing.
As the name implies, Antagonistic pairs is when muscles are set down or grouped in pairs. that is when a muscle tightens or shortens (contrast) and pulls, the other muscle will then be in a relaxed state so as to allow movement.
There is a great need or importance for antagonistic pairs in muscles. That is Muscles do perform its role in an antagonistic pairs because they can only reduce (shorten)making or taking the movement in one direction. There is also the need for another muscle that shortens in order to lead/make movement go in the opposite direction.
Example of this antagonistic muscle pairs is commonly found in insects where their exoskeleton in the hind leg of the insect gives room for the muscles to work in antagonistic pairs, also the tibia flexes and others.
therefore, we can conclusively say that the statement that Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax is true.

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.

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!
