The atmosphere exerts a force on earth. Why does yhe atmosphere exert pressure on earth?
Answer:
The atmospheric molecules have energy because they have a quantifiable temperature. It vibrates and circulates, and bumps into other gas molecules. Most of them are elastic, which means that the molecules bounce off more than they stick together. The "bump" is a strength. It becomes pressure when applied over an area, such as your skin or earth's surface.
Explanation:
How much is the pressure of the atmosphere?
Pressures are determined by height (mostly by the volume of water vapor), temperature, and weather. The average air pressure, however, is 14.7 pounds per square inch, 29.92, or 1.01 to 105 paschal in regular conditions at the marine level. At 5 km altitude, atmospheric pressure is just about 50%. (about 3.1 miles).
Why is the Earth's surface under pressure so much higher? It's because the weight of all the air at that location really is measured. There's not much air around you to press down while you are high in the atmosphere. The whole atmosphere is heaped above you on the surface of the Earth. While the gas molecules are extremely light and distant, they are many!
A fish of genotype a/a ; B/b is crossed with a fish whose genotype is A/a ; B/b. What proportion of the progeny will be heterozygous for at least one of the genes
Answer:
Proportion of heterezygous progeny = 3/4
Explanation:
According to Mendel's law of independent assortment which states that the alleles of two (or more) different genes get sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele received for another gene.
Gametes produced by the fishes assuming independent assortment:
Fish 1 = aB, ab, aB, ab
Fish 2 = AB, Ab, aB, ab
Progeny from cross:
aBAB, aBAb, aBaB, aBab
abAB, abAb, abaB, abab
aBAB, aBAb, aBaB, aBab
abAB, abAb, abaB, abab
Proportion of heterezygous progeny = 12/16 = 3/4
What is the effect of the angle of the Sun on the insolation an area receives?
Answer:The sun angle at a place varies over the course of the year as a result of the constant tilt and parallelism of the earth's axis. As the sun angle decreases, light is spread over a larger area and decreases in intensity (energy input per unit area)

You are asked to study a new inhibitor of oxidative phosphorylation. When it is added to a suspension of mitochondria carrying out this process, both ATP synthesis and oxygen consumption are inhibited. You suspect that the inhibitor blocks either the F-type ATPase or the electron transport chain. You can perform an experiment that measures the consumption of oxygen and the synthesis of ATP by isolated mitochondria. In one paragraph (6 sentences maximum), explain how the uncoupler, dinitrophenol, can be used to determine whether the inhibitor blocks the ATPase or the electron transport chain.
This was all the information that was given.
Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
A summary of the article history of the cell discovering the cell
Which statement best describes cancer cells?
A.cells that go through mitosis successfully
B.cells that continue to replicated even when not needed and does not stop
C.cells that move to G0,the resting phase
D.cells in hypotonic, solution to burst
Answer:
B!
Explanation:
Cancer is a essentially a mistake in a cell's DNA. This is very gradual, and takes a while. The immune system deals with most of them, but some slip out of reach and continue to mutate until they grow into tumors, or large pockets of cancer cells. Since their genetic code is very messed up at this point they have no limitations on growth.

As a college student, you are no doubt concerned about the grades that you earn while completing your coursework. If you wanted to know how overall GPA is related to success in life after college, how would you choose to approach this question and what kind of resources would you need to conduct this research?
I am not a college student, I am a Freshman in High School but if I were in college this is what I would say:
In college the GPA of the student is very important and it helps a student obtain good colleges and courses in this regard.
The data collected from college alumni about their careers after college would be the required resource in this case.
What is meant by a research resource?
The kind of research one wants to do and the kind of questions in mind guide the kind of resources required for research. Currently, access to any kind of information for anyone is greater than ever before.
Thus, for good research, it's important to collect data from the right kind of resources. It needs to be located, organized, evaluated, and used for the communication of information.
Various places can be a home for a research resource or be research resources themselves. These can be traditional libraries. Whereas, personal experiences can be important research resources.
Print media, which includes journals, books, brochures, newspapers, and magazines are conventional research resources. Currently, electronic sources found on the Internet are being used. Interviews or surveys can also be considered research resources.
Therefore, to understand the impact of GPA on students' careers, we need to collect data on their careers.

Explanation:
Which of these parts of the membrane help large molecules pass through it?
A. Phospholipid bilayers
B. Phosphorus groups
C. Globular proteins
D. Fatty acids
Answer:
A. Phospholipid bilayer
Explanation:
Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.
The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.
Answer:
Globular proteins! The other answer is sadly wrong.
Explanation:
I just took the quiz. Many globular proteins positioned throughout the cell membrane help the large, polar molecules across. These globular proteins in the cell membrane are the membrane proteins.
Also, I accidently put a 1 star on my own answer, but it's correct.

Define invasive species
Answer:
An invasive species is a non-native species that spreads from the point of introduction and becomes abundant. The invasive species label attaches only to populations of species whose impact upon introduction has altered their new environment.
Explanation:
Answer:
Invasive species
Explanation:
An invasive species is an animal imported from another country. For example: the Giant African Snail. Hence their name, the Giant African Snail came from Africa. They first came into Florida as pets, and were then released into the wild. Since then, they have spread across the state. These snails eat plants voraciously, damaging crops and competing with local wildlife. They will also eat stucco, wood, and plaster, causing thousands of dollars in damage.

Explanation:
A eukaryotic cell has 6 chromosomes, explain what you would get at the end meiosis.
Answer:
If a eukaryotic cell has 6 chromosomes, the end result after meiosis is two daughter cells with 3 chromosomes each.
Explanation:
Meiosis is the process of cell division by which sex cells or gametes are formed. It is a mechanism of reductive division, since the chromosomal charge of a eukaryotic cell —diploid— is reduced by half, that is, haploid cells are obtained.
A diploid eukaryotic cell with 3 pairs (6) of chromosomes, after meiosis produces two haploid daughter cells, with 3 chromosomes each.
This process of reductional division, where the gametes are obtained, aims to ensure that when the gametes of each parent join together they form a diploid cell, the zygote.

Consider a scenario where a person eats a cupcake composed of glucose molecules. The person has digested the cupcake, and the glucose has been absorbed into the bloodstream. Based on this information and your knowledge about biology, select true or false for each of the following statements.
a. Some of the energy stored in glucose will eventually be transformed into heat.
b. Carbon atoms from glucose could be exhaled by the person as carbon dioxide.
c. Carbon atoms from glucose could later be found in a plant cell.
d. Carbon atoms from glucose could be converted into oxygen during metabolism.
Answer: a.b.c-true.
d-false.
a. Some of the energy stored in glucose will eventually be transformed into heat.
This is through the process of Glycolysis (and Krebs's cycle )where the Carbon atoms in the glucose(substrate level phosphorylation) undergo metabolism with the liberation of ATPs as heat during metabolisms. The glucose serves as the substrate for the generation of heat.However,largest amount of ATP's is expended as heat during oxidative phosphorylation,due to the glucose used as substrate in preceding stages of glycolysis and Kreb Cycle.
b. Carbon atoms from glucose could be exhaled by the person as carbon dioxide.
Yes, this is through glycoylsis and kreb's Cycle where CO2 is given off as during metabolisms as one compound change from one form to another.E.g from Citric acid(6C) to Succinate(5C),some Carbon atoms are lost as C02. Like during glycolysis.
C. Carbon atoms from glucose could later be found in a plant cell.Yes this is because the CO2 expired by human could be trapped by green plants and react with water in the presence of sunlight trapped by chlorophyll to form carbohydrate in plants.This is photosynthesis.
Explanation:
Carbon can't not be converted to oxygen,big FALSE.
