During the cell cycle, normal cells exit the G1 phase and enter the Go phase where they rest. Typically,
cells will reenter the cycle at G1 prior to going on to S phase. However, abnormal cells such as cancer
cells, may not be allowed to enter the Go phase to rest.
As a result, these cells will most likely -
F. mutate during G2 phase
G. continuously repeat the cycle
H. die after DNA replication
J. fail to complete mitosis
Abnormal cells such as cancer cells, may not be allowed to enter the G0 phase to rest. These cells will most likely continuously repeat the cell cycle.
What do you mean by Cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.
The abnormal cell undergoes a repeated cell cycle because they express an enzyme called telomerase that switches the wearing down of chromosome ends.
This happens normally in the cell cycle, and after multiple repeated cycles, such abnormal cell undergoes apoptosis.
Therefore, abnormal cells such as cancer cells, may not be allowed to enter the G0 phase to rest. These cells will most likely continuously repeat the cell cycle.

In this question we will transcribe DNA to RNA
What is DNA and RNA?It consists of a pentose, a phosphate and has
adenineguaninecytosine and uracil as nitrogenous bases.RNA, unlike DNA, is composed of only one strand and it is produced in the cell nucleus from one of the strands of a DNA molecule. Once ready, the RNA goes to the cell cytoplasm, where it will perform its main function, which is to control protein synthesis.

Distinguish how an animal welfare activist would most likely feel about the animals’ housing and training in the following scenario.
A traveling circus uses a number of animals in its act, including a tiger and a small herd of elephants. When traveling, the tiger gets its own car and attendants who feed it regularly. The elephants are dispersed among three cars and each has a number of attendants who feed and clean up the elephants’ waste. To train the animals, the circus hires animal trainers who use whips to teach the animals how to behave in the ring.
Answer:
using whips on animals is not a desirable activity, as well as circus' being notorious for the mistreatment of animals, I think anybody who had these animals welfare in mind would disapprove of this scenario

What explains how the parents in a family both have the same eye color, but some of their children have a different eye color? Assume for this example that eye color is determined by a single gene.
A. One parent is homozygous dominant, and the other heterozygous for a gene that controls eye color allowing some of the children to express a different trait.
B. The parents are both homozygous dominant for a gene that controls eye color allowing some of the children to get two recessive alleles.
C.One parent is homozygous dominant, and the other homozygous recessive for a gene that controls eye color allowing some of the children to express a different trait.
D. The parents are both heterozygous for a gene that controls eye color allowing some of the children to get two recessive alleles.
The correct option is D. The parents are both heter0zyg0us for a gene that controls eye color allowing some of the children to get two recessive alleles.
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
In the exposed example, let us assume that the alleles that code for eye color are the followings,
E is the dominant allele and codes for the dominant colore is the recessive allele and codes for the recessive colorIf at least one parent is h0m0zyg0us dominant for the trait, EE, the whole progeny will express the dominant trait because all of them will carry at least one dominant allele.
If both parents are heter0zyg0us Ee, some children will express the dominant trait and some other the recessive trait. This is because some of the children receive at least one dominant allele and some others only receive recessive alleles.
Cross:

Explain how cancer cells grow.
Answer:
Gene mutations in cancer cells interfere with the normal activity within a cell.This can cause it to grow out of control and/or not die when it should. Cancerous cells can continue to grow because they behave differently than normal cells do. Cancer cells differ from regular cells in many ways,one of their more apparent traits is that they divide quickly with no control over them.The amino acid glutamine is one of the many key factors to helping the growth of cancer cells. Like all cells, cancer cells need nutrients to grow,sugar is one important fuel for it's development, but is far from the only factor.

based on the data, what can you infer about the relative pH of the stomach?
The pH of stomach is important as it helps to induce the digestive enzyme called pepsin. The presence of HCL i.e., hydrochloric acids in stomach results in the pH of stomach to become acidic which range from 1.5 to 6.5 values.
What is the pH level of stomach?When the bolus enters the stomach, it aids the release of gastric juice having enzymes, mucous and HCL.
The upper and lower parts of stomach have varying pH values. Upper part has a pH of 4−6.5, while the lower part is with a pH of 1.5−4.0 which is highly acidic due to HCL.
Thus, the relative pH of stomach is acidic ranging from value 1.5 to 6.5.

what kind of mutation does this image represent
Answer:
A. Deletion
Explanation:
The kind of mutation that this image represent is deletion. The correct option is A.
What is mutation?A variation in the usual DNA sequence at a specific gene locus. Although the term has a negative connotation, mutations (including polymorphisms) can have a negative, positive, or neutral effect on cell function.
Mutations can occur as a result of errors in DNA replication during cell division, mutagen exposure, or viral infection.
Germline mutations (those found in eggs and sperm) can be passed on to offspring, whereas somatic mutations cannot.
In genomics, a deletion is a type of mutation that involves the removal of one or more nucleotides from a segment of DNA. A deletion can result in the loss of any number of nucleotides, ranging from a single nucleotide to an entire chromosome.
Thus, the correct option is A.
