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.

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.

How do chemoautotrophs make energy?
Answer:
Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide. These organisms are able to produce their own source of food, or energy. The energy required for this process comes from the oxidation of inorganic molecules such as iron, sulfur or magnesium.
Explanation:
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 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

.Explain why the scientific process is important when learning about diseases.
Answer:
The scientific process is important when learning about diseases because it allows to obtain reliable and valid knowledge about the different existing diseases, it helps in solving problems correctly and it is the best tool to nullify arbitrary opinions regarding a diagnosis or treatment, taking into account each of its stages.
Explanation:
The scientific method is a process through which relationships between facts are established to arrive at the verification of something. Through this step by step in which facts are discarded and added, the answers to findings are based. It is through the information generated by the research that it is possible to associate and / or integrate a set of symptoms and signs with a probable nosological diagnosis. Similarly, the selection of treatment and even the prognosis of patients depend on the information obtained from a population of subjects who share attributes; they depend, in a word, on research. Bearing in mind the scientific process, scientific thinking develops with practice, and for this it is necessary that there be constant reflection on the problems, have guides for the interpretation of medical reading, develop research protocols, learn to collect and analyze data about diseases.
Scientific is very important in order to obtain information about the disease.
The scientific process is important when learning about diseases because it provides information about various aspects of diseases as well as provides solution about cure of the disease.
This scientific process or method can be used for obtaining information about the causes of disease, its causing agents and cure for the disease so we can conclude that scientific is very important in order to obtain information about the disease.

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.

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.

Justin wanted to explain the water cycle to his class. He created a chart with labels and illustrations
The given question is incomplete, however, the questions related to this is as follows:
What are the characteristics of the water cycle?
What part do plants play in the water cycle?
Answer:
The correct answer is -
- The characteristics of the water cycle are evaporation, transpiration, condensation, precipitation, surface runoff, and groundwater.
- Plants perform transpiration.
Explanation:
The water cycle is the movement of the water in between different spheres of the earth that include the atmosphere, hydrosphere, geosphere and biosphere. The water cycle has various components and processes that complete the water cycle and connect different spheres.
The components of the water cycle are evaporation of water and transpiration from the hydrosphere or geosphere and plants respectively to the atmosphere. The condensation and precipitation to water again to the geosphere and hydrosphere from atmosphere and runoff on the surface on earth to the water resrvoirs.
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!
