Answer:
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries.
Answer:
The greenhouse effect is a natural phenomenon, which, helps maintain the relatively stable, livable, range of temperatures that we find on earth. To better understand how this phenomenon works, scientists have used the analogy of the greenhouse. In a greenhouse, the glass (the atmosphere) allows the radiant energy (light) of the sun to enter. As the radiant energy strikes various plants, gases, and objects in the greenhouse, they heat up. Their heat is then released back into the air of the greenhouse as infrared radiation (heat). This infrared radiation cannot travel through the glass and remains inside the greenhouse, increasing the temperature inside the greenhouse. Temperatures can be controlled, or kept in balance, by allowing some of the heat to remain inside and some to be vented to the outside. Under normal conditions, the earth's atmosphere works in a similar manner. Solar radiation enters the atmosphere and heats up the air molecules, the surface of the earth, buildings, plants, and other objects. These objects in turn, radiate infrared radiation back out into the atmosphere, where some of this radiation is absorbed by the greenhouse gases, and some is radiated out into space. As some of the heat stays in the atmosphere and some escapes into spaces, a balance is maintained allowing our planet to have a relatively stable range of temperatures. Scientists believe that as the greenhouse gases become more abundant in the atmosphere, due mainly to the burning of fossil fuels, they retain more and more infrared radiation, allowing less and less to escape into space, tipping the balance toward heating up the atmosphere, resulting in a changing and warmer climate, planet-wide. This is the accelerated greenhouse effect.

the disease kwashiorkor is caused by a diet which is very low in protein. the concentration of proteins in blood plasma is much lower than usual. one of the symptoms of kwashiorkor is swelling caused by build-up of tissue fluid. suggest why this is so.
Answer:
Proteins play a crucial role in regulating the distribution of water in the body. Specifically, proteins in the blood plasma help to maintain the balance of fluids between the blood vessels and the surrounding tissues by creating a pressure gradient that keeps fluids from leaking out of the vessels. When the concentration of proteins in the blood plasma is much lower than usual, as is the case in individuals with kwashiorkor, this pressure gradient is disrupted, and fluids begin to leak out of the blood vessels and accumulate in the surrounding tissues. This can result in swelling, or edema, in various parts of the body, including the feet, legs, and belly.
Answer:
The low concentration of proteins in the blood plasma causes a decrease in the osmotic pressure of the blood. This decrease in osmotic pressure causes water to move from the blood into the tissues, leading to an accumulation of tissue fluid and swelling.

Selection that favors individual geckos with red scales and individuals with green scales in a population is best described as.
Selection that favors individual geckos with red scales and individuals with green scales in a population is best described as Diversifying selection .
What is meant by Diversifying selection ?This broadens the selection. Diversifying selection occurs when the environment promotes two "extreme" or dissimilar phenotypes, as is the case with the red and green scales in this instance.
Due to the fact that external influences typically favor one trait value, it cannot be stabilizing or directing. When it chooses a non-extreme phenotype, it is stabilizing; when it favours a single extreme phenotype, it is directional.
Diversifying selection, also known as disruptive selection, happens when extreme levels of a trait are preferred above the middle values. Often, speciation is driven by this kind of selection. Additionally, environmental changes that favor people at one extreme of the phenotypic spectrum might result in diversifying selection.
It cannot be frequency-dependent because that merely depends on the occurrence rates of various phenotypes and genotypes and is "random,"
The complete question is : Selection that favors individual geckos with red scales and individuals with green scales in a population is best described as
a. diversifying selection.

Suppose that each fatty acid in a certain fat can make 9 molecules of acetyl CoA. Predict how many ATP can be made from the fatty acids in this fat
The number of ATP yielded through fat metabolism which makes 9 molecules of acetyl CoA is 108 ATP.
How many ATP produced on beta-oxidation?The process of metabolic reactions which convert fatty acids to acetyl CoA is called beta-oxidation. Through multiple steps in beta-oxidation, fatty acids are broken down to produce energy (ATP). Before producing the energy, fatty acids which are made up of carbons must be converted into acetyl CoA in advance.
If 9 molecules of acetyl CoA are produced, it indicates that the fatty acid has 18-Carbons. In other words, each acetyl CoA contains two carbon atoms.
Each acetyl CoA that has been produced, will enter into the citric acid cycle or known as Kreb’s cycle. This cycle yields 3 NADH (9 ATP), \(FADH_{2}\) (2 ATP), and 1 ATP. The total ATP result is 12 ATP.
when there are 9 molecules of acetyl CoA, the ATP yielded is 9 x 12 ATP = 108 ATP.
Thus, if each fatty acid in a certain fat can make 9 molecules of acetyl CoA, the amount of ATP that can be made is 108 ATP.

A bicycle rider increases his speed from 5 m/s to 15 m/s in 10 seconds.
The cyclist accelerates at a rate of 1 m/s^2.
What is speed?Speed is a unit used to describe how quickly an object is moving in relation to a fixed point. The distance an object moves in a unit of time, commonly measured in meters per second (m/s) or kilometers per hour (km/h), is referred to as a scalar quantity.
How do you determine it?This issue can be resolved using the acceleration formula. This is the equation for acceleration (a):
a=(vf - vi) / t
where t is the amount of time required, vi is the initial velocity, and vf is the final velocity.
In this instance, the time taken (t) is 10 seconds, the final velocity (vf) is 15 m/s, and the initial velocity (vi) is 5 m/s. When these values are added to the formula, we obtain:
(15 m/s - 5 m/s) / 10 s =a
a = 1 m/s^2
The cyclist's acceleration is 1 m/s^2.

A couple is expecting a child. The fetus undergoes genetic testing and the couple discover the fetus has sickle cell anemia. The couple ask the nurse how this happened. Which statement is accurate for the nurse to provide? a."Sickle cell anemia can be passed to the fetus in many ways. We will know more at birth."
b."Sickle cell anemia is passed to a fetus when one of the parents has the gene."
c."Sickle cell anemia occurs from a random genetic mutation."
d."Sickle cell anemia is passed to a fetus when both parents have the gene."
The nurse should inform the couple that (d) "Sickle cell anemia is passed to a fetus when both parents have the gene". Therefore, option d is the accurate statement for the nurse to provide.
Sickle cell anemia is an inherited blood disorder. It causes the production of abnormally shaped red blood cells, which become sticky and rigid and may get stuck in small blood vessels in the body. This can cause severe pain and organ damage, as well as increase the risk of infection, stroke, and other complications.
The technique of genetic testing is used to detect gene mutations that cause various disorders. In the case of sickle cell anemia, it is caused by a mutation in the gene that is responsible for making hemoglobin, the protein that carries oxygen in the blood. When both parents have a copy of the mutated gene, their child is at risk of inheriting sickle cell anemia.
