During the S-phase of the cell cycle, DNA makes an exact copy of itself in one of the following processes. The process that makes an exact copy of a cell’s DNA is called a.translationb.transcription c.replicationd.synthesis
Answer:
Replication
Explanation:
During the process of replication DNA (genetic material) makes copies of itself to make two identical DNA molecules. it is one the most basic processes within a cell.
As a cell grows it’s Increase more than it’s.
Answer:
volume
surface area
Explanation:
The growth of the cell includes the increase in the mass of the cell by the absorption of nutrients and elimination of the wastes. This process helps the cell to grow in size. In this process, the volume of the cell increases faster than the surface area. This gradually leads to the decrease in the surface area of the cell. The increase in the volume expands the cell membrane also.
What is a reservoir and what is its
main purpose?
Answer:
A reservoir is type of lake that is used to store water. Its main purpose is to collect water during very rainy times or when snow on a mountain is melting,reservoirs also control flooding.
What is denaturation? What are some things that can cause this to happen?
Answer:
If a protein loses its shape, it ceases to perform that function. The process that causes a protein to lose its shape is known as denaturation. Denaturation is usually caused by external stress on the protein, such as solvents, inorganic salts, exposure to acids or bases, and heat.

Explanation:
Investigation of HOX genes indicates that the animal family tree" can be simplified to only how many different types of animals?
Answer:
three evolutionary lines
Explanation:
The Hox genes are master developmental genes found in animals, which are involved in the regulation of development by specifying the body plan of an embryo along the head-tail axis. Recently, several research groups studied the assortment of the Hox genes in three different marine organisms: 1- a priapulid worm (an unsegmented marine worm), 2- a brachiopod (phylum Brachiopoda), and 3- a polychaete worm (related to earthworms). Then, these research groups combined their research efforts to compare the assortment of the Hox genes observed in these species to those observed in previously studied animals including, among others, mice, fruit flies and sea urchins. From this combined study, researchers concluded that the animal kingdom can be divided into three primary evolutionary lineages.

Which two terms are most closely related to learned behavior?
Complete question:
Which two terms are most closely related to learned behavior?
insight and trial-and-error reflex and insight instinct and trial-and-error imprinting and reflexAnswer:
insight and trial-and-errorExplanation:
Learned behavior: The learned behavior is the one that the organism develops as a result of experience. Learned behavior contrasts with innate behavior, genetically programed that are performed with no previous experience. This behavior is not inherited from parents to progeny; instead, it is developed during life as a result of experience and environmental influence. Learned behavior allows the individual organism to adapt to changes in the environment, and they modify by the different experiences. Insight learning: Learning that the individual gains when faces a problem for the first time and behaves to resolve it. Trial-and-error learning: Learning that the individual gains when facing a situation and trying to solve it in different alternative ways that might fail, until one of them is the correct one.When the animal or the organism faces a problem or a situation for the first time, with no previous knowledge or innate knowledge of how to solve it, it must deal with the situation in different ways until finding the solution or the correct way to get over it. Once the animal gets over the situation, it learns how to behave the next time.

Body systems interact with one another to carry out life processes. When we eat food, it is broken down into nutrients that can then be used by body cells for metabolic processes and building cellular structures. Many body systems are involved in this process.

Using indoor tanning bed before the age of 35 can increase your risk of melanoma, the deadliest form of skin cancer, by 59 percent. The risk increases with each use. Research demonstrates that even people who do not burn after indoor tanning or sun exposure are at an increased risk of melanoma if they tan indoors; therefore, exposure to the radiation emitted by tanning beds can cause skin cancer. This cancer is the direct result of a:
a) mutation in a protein
b) mutation in the genetic material
c) change in fat molecule
d) change in a starch molecule
Answer: mutation in the genetic material
Explanation: just took the test and got it right
This cancer is the direct result of a mutation in the genetic material.
What is Mutation?Genetic mutations, which occur as your cells divide and generate duplicates of themselves, are modifications to your DNA sequence. Your DNA teaches your body how to develop and work.
Genetic changes may result in diseases like cancer or, in the long run, may enable people to adapt to their environment more successfully.
A change in the DNA sequence is referred to as a genetic mutation. Your cells receive the information they require to carry out their functions from your DNA sequence.
Therefore, This cancer is the direct result of a mutation in the genetic material.

Jorge is drawing an atomic model. The part of the atom that he has drawn is shown below. What does Jorge need to add to complete his atomic model?
Answer:
An atom is the smallest particle in a chemical element that holds its chemical properties. Although in the past it was thought impossible to break an atom, within modern chemistry we know that an atom is composed of subatomic particles, which compose the atomic model:
1) electrons, which have a negative charge, such a small size that it is immeasurable, and a mass much smaller than the other two subatomic particles; 2) protons, which have a positive charge; and 3) neutrons, which have no charge.
The protons and neutrons form a dense and massive atomic nucleus, which is called multipons nuclei. The electrons form a cloud of electrons that surround the nucleus.

By the 1950s, there was Choose... major variety(ies) of banana being grown commercially in the world. Then, a soil fungus called Fusarium struck the banana plants, causing Panama Disease. Because of Choose... , the bananas could not resist the fungus. Within a few years, the entire commercial banana industry had collapsed. The industry switched to a different kind of banana. Yet fifty years later, Panama Disease has returned, and there is still no cure for it. Scientists argue that the best solution for the future is Choose... .
Answer:
Produce resistance variety or use of fungicides.
Explanation:
The best solution for the future is to produce resistance variety to Panama Disease or fungicide spray that kills Fusarium fungus that causes Panama Disease. If the variety is resistance against Fusarium fungus so they get no adverse affect from it. The use of chemical that kills Fusarium fungus is also a good method to protect banana industry from the adverse effect of this disease.
