Answer:
carbon dioxide- burning of fossil fuels
fluorinated gases- industrial processes
methane- production and transport of oil and natural
gas
nitrous oxide- agricultural and industrial activities
Explanation:
Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.
Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.
Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.
Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.
Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.

Which statement does not support the endosymbiotic theory?
1.) Mitochondria and Chloroplasts reproduce independently from the cell.
2.) Mitochondria and Chloroplasts contain their own ribosomes.
3.) Mitochondria and Chloroplasts have DNA that resembles bacterial DNA.
4.) Mitochondria and Chloroplasts are much larger than prokaryotic cells.
4.) Mitochondria and Chloroplasts are much larger than prokaryotic cells.
no, they are about the same size, another good argument for the endosymbiotic theory is the presence of prokaryotic ribosomes (30S)
The statement that does not support the endosymbiotic theory is:
4.) Mitochondria and Chloroplasts are much larger than prokaryotic cells.
Lynn Margulis, in her endosymbiotic theory, proposes that eukaryotic cells evolved by incorporating prokaryotic organisms into their cytoplasm.
This theory is reinforced by the following facts:
Mitochondria and chloroplasts have some genetic information of their own, which would support their original independence.Both the mitochondria and the chloroplast have their own circular double-stranded DNA freely inside them, independent of the nuclear one. They behave like a bacterium, because they synthesize their own proteins, use 70s ribosomes (and not 80s ribosomes like eukaryotes), perform their functions through the membrane and replicate their DNA and perform binary fission to divide.Therefore, we can conclude that Mitochondria and Chloroplasts are much larger than prokaryotic cells is the statement that does not support the endosymbiotic theory.

Egg membranes from three eggs were carefully taken out and labeled as a, b , c. Each of these membranes were filled with 1% solution of sugar. Membrane A was immersed in 0.5% sugar solution, Membrane B was immersed in 1% sugar solution and Membrane c was immersed in 2% sugar solution. Predict the behavior of the three membranes?
Answer:
The correct answer would be -
Membrane A - Hypotonic solution - the movement of water towards inside the cell
Membrane B - Isotonic soltion - there will be no movement of water
Membrane C - Hyertonic solution - the movement of water towards outside of the cell
Explanation:
This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.
In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.
Thus, the behavior of the membranes are-
Membrane A - Hypotonic solution - the movement of water towards inside the cell
Membrane B - Isotonic soltion - there will be no movement of water
Membrane C - Hyertonic solution - the movement of water towards outside of the cell

What could happen if the cell cycle for the cells in your pinky finger stopped functioning properly? (Check all that apply.)
Answer:
Hello, you did not enter the answer options, but I can help you by explaining what would happen in this case.
if the cell cycle of the cells in your little finger stops working properly, two things could happen. First, if these cells were unable to start and complete the cell cycle, your finger would be unable to heal cuts and bruises that could happen to it, on the other hand, if these cells were unable to end the cell cycle, your finger would develop cancer .
Explanation:
The cell cycle allows the cells of your circus, in this case, of your little finger, to multiply and create exactly the same cells. This process is very important to not only make your finger grow, but also to be able to heal cuts and bruises, regenerating the tissues and skin of your finger.
Unfortunately, over time, or as a result of some factors, cells may have defects in the cell cycle. In short, if the cells are unable to start and complete the cell cycle, your finger will be unable to create new cells and regenerate tissues and skins if your finger is cut or injured. In addition, the cells may not be able to finish the cell cycle and multiply in an exaggerated and unregulated way, generating a cancer in the finger.

What major factors play a role in global warming? decrease in human activity and normal climate conditions natural factors and human activity natural factors and normal climate conditions decrease in human activity and natural factors
Answer:
natural factors and human activity
Explanation:
Global warming is the gradual increase in the earth's atmospheric temperature. It is a cause of concern for every country as it affects the whole planet. Global warming is caused by the production and release of Greenhouse gases into the atmosphere.
Greenhouse gases like C02, methane, nitrous oxide etc. are gases that have the ability to trap heat energy, hence, the increased accumulation of these gases in the atmosphere leads to a rise in global temperature.
The emission of greenhouse gases, which in turn induces global warming effect, is majorly contributed by natural factors and human activities. Natural occurrences like volcanic eruption etc release these gases into the atmosphere. Also, on a large part, the emission of CO2 caused by the burning of fossil fuels is the major problem. This burning of fossil fuels is carried out by humans. Coals, petroleum and other non-renewable source of energy are used daily, which creates havoc to the environment.
Therefore, the contribution of natural factors and human activities play a huge role in global warming.

You are in your room listening to music and, realize you are thirsty, you can feel that your soda is no longer cold, and you decide to invite a friend over. What parts of the central nervous system would be primarily involved in each of these italicized behaviors
Answer:
Internal region of the brain and the hypothalamus are related to the sensation of thirst.
Thalamus is involved with the perception that the soda is not colder.
Explanation:
The central nervous system is the body system responsible for making your body receive information and respond appropriately, promoting full bodily functioning. It is formed by the brain, spinal cord and the components that form them.
Regarding the activities shown in the question above, we can say that some components of the brain are related. For example: The innermost part of the brain and the hypothalamus are related to feeling thirsty. This is because the inner part of the brain is responsible for making the brain understand how the organism is functioning, if something is missing or if there is any discomfort that needs to be resolved. The hypothalamus, in turn, is responsible for the release of hormones that signal that your body's homeostasis is unbalanced. With the interaction of these two structures you realize that you are thirsty.
In addition, the thalamus is responsible for allowing your body to receive sensory messages. It is this structure that allows you to realize that your soda is not cold when you touch the glass, or take a sip of it.

Which is the correct sequence of events when the RER delivers transport vesicles to the Golgi apparatus? 1 – Small vesicles move material from one cisterna to the next. 2 – Enzymatic modification occurs. 3 – Arrival at the trans face. 4 – Arrival at a cisterna known as the cis face."
Answer:
The correct order of events when RER delivers transport vessicles to the Golgi apparatus are;
4,2,1,3
Arrival at a cisterna known as the cis face."
Enzymatic modification occurs.
Small vesicles move material from one cisterna to the next.
Arrival at the trans face.
Explanation:
Rough endoplasmic recticulum are flat sacs in the cytoplasm that help in the synthesis of protein. It vesicle or sac floats through the cytoplasm to the Golgi apparatus and is absorbed. The Golgi apparatus is an organelles in the cytoplasm that help to package protein into membrane bound organelle in the vessicles.
The vessicles that bud off join to the rough endoplasmic recticulum, Molecules travel through the Golgi apparatus through the vesicle transport till they get to the end of the assembly line at the biggest sacs from endoplasmic recticulum called the trans-Golgi.
Firstly, the particles arrive at cisterna known s Cis face. The cis face is the end of the organelle where substances enter from the endoplasmic reticulum for processing into the Golgi apparatus.
Then there is enzymatic modifications which is done by the activities of enzymes.
Small vessicles then Transport material from the cisterna.
It is then transported to the trans face. The trans face is where the particles leave in the form of smaller detached vesicles.
Hans has a low sperm count. His wife Sharon is fertile and has a child from a previous marriage. They are exploring options to improve their chance of conceiving. Which option makes sense given the situation?
Answer:
Intrauterine insemination IU
Explanation:
In this scenario the required numbers of sperm are not released in the semen of the Hans needed to fertilize Sharon ovum..Therefore,a technique is needed to directly inject an healthy sperm, into her uterus to fertilised her ovum directly,the technique is IU.
It is a process which involve the selection of healthy sperm.and injected this during ovulation in the female.With this procedure,the likelihood of fertilization and pregnancy occurring is high,as the distance,time and competition with other sperm cells is reduced.This makes the procedure reliable.
It is simple technique which involves the sperm washing to get the best concentration of sperm to use, monitoring of the ovulation and optimal timing; which targets best time of ovulation,usually day 1 or day 2 after ovulation.
it is relatively less expensive.

Read the text: Trans fat is obtained industrially after certain vegetable oils, under certain conditions, are hydrogenated and transformed into solid fat. This type of fat has been used in the production of some food products, such as stuffed cookies, giving them, for example, a more crunchy consistency. However, it is admitted that the excessive consumption of trans fat contributes to obesity and the development of cardiovascular diseases. a) What group of lipids do oils and fats belong to? b) How can we differentiate oils from fats at room temperatures, around 20 ° C? c) Many seeds, such as soybeans, store relatively large amounts of oil. What is the importance of the presence of oil for the embryo of oil seeds? d) Birds and mammals store fats in adipose tissue, under the skin. What is the advantage of the fatty layer under the skin being especially developed in animals that live in cold climates, such as polar bears? e) Recent studies indicate that fat is associated with cardiovascular disease. Name another substance in the lipid group also commonly associated with these diseases.
Answer and Explanation:
a) What group of lipids do oils and fats belong to? Lipids and fats belong to the triglyceride group. Triglycerides are a mixture of glyceride esters and fatty acids. They are stored in specialized adipose cells, known as adipocytes. Adipocytes give a place to the adipose tissue in the organism.
b) How can we differentiate oils from fats at room temperatures, around 20 ° C? At room temperature, fats can be recognized for being solid, while oil is liquid.
c) Many seeds, such as soybeans, store relatively large amounts of oil. What is the importance of the presence of oil for the embryo of oil seeds? The plant´s embryo needs to nurture while it is developing. The oil in the seeds plays the role of nutritive storage, together with other nutritive substances. These are used by the plant until it is able to photosynthesize.
d) Birds and mammals store fats in adipose tissue, under the skin. What is the advantage of the fatty layer under the skin being especially developed in animals that live in cold climates, such as polar bears? The advantage of the fatty layer under the skin is to keep or maintain the animal´s temperature. It is very common to find a thick fatty layer under the skin of animals that live in very cold environments, such as polar bears or deep divers marine mammals.
e) Recent studies indicate that fat is associated with cardiovascular disease. Name another substance in the lipid group also commonly associated with these diseases. Cholesterol is a fatty substance needed for the good functioning of the organism. It is part of cellular layers and it plays a role in hormone synthesis and biliary salts. Although in excess they might be harmful as they tend to accumulate in the artery´s walls, blocking the passage of blood. This can lead to a heart attack.

A coral reef that has lost a significant number of its species due to water pollution best be described as a biodiversity hotspot, hence option A is correct.
How coral reef act as a biodiversity hotspot?This is so that fish, crustaceans, and other living things have a place to dwell thanks to coral reefs. They are more ecologically diverse than rainforests. And ecosystems depend on biodiversity for food, health, and resilience. Similar to a soccer team without a defense is a loss of biodiversity.
Many people think coral reefs contain greater biodiversity than any other environment on the earth, even more than a tropical rainforest. More than 25% of all marine life lives on coral reefs, which make up less than 1% of the ocean floor.
Therefore, a coral reef that has lost a significant number of its species due to water pollution best be described as a biodiversity hotspot.
