A. A mutation in a gene that decreases cell devision
Explanation:did the test
Cancer is a mutation in a gene that decreases cell division.
What are the features of cell division?
Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.
Moreover, these phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells.

In chili peppers, hot (H) flavor is dominant over mild flavor (h). If a chili grower wanted to grow only hot peppers, which of the crosses below would produce the largest number of hot flavored offspring? (Make a punnett square using the answer choices to find the correct answer.)
In punnett square, the crossing result will be HH,Hh,HH,Hh which means all are going to be hot chili peppers since H (dominant) is present in all of them.
What do you mean by punnett square?The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905.
A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding.

Deletion of a DNA base from a gene affects an organism by—
Causing future gametes to have additional chromosomes
Changing the sequence of amino acids in a protein
Causing chromosome fragments to form long chains
Changing the structure of ribose sugar in nucleic acids
Answer:
Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.
Explanation:
A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:
Transcription of the mRNA, which will have the sequence of altered bases. During translation, the mRNA codons will encode at least one different amino acid. The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.In summary, the deletion of a base in the DNA will affect the protein to be synthesized by changing the amino acid sequence of its structure.
The other options are not possible, because the deletion of a base in the DNA of a gene
Does not influence the number of chromosomes that the gametes will have.
It does not produce long chains in the chromosomes.
It does not affect the ribose structure of the nucleic acids.
Deletion of a DNA base from a gene affects an organism by :
B) Changing the sequence of amino acids in a protein.
DNADeletion of a DNA base from a gene affects an organism by the changing the sequence of amino acids in a protein.

Explain the biological significance of menstruation?
Answer:
Menstruation occurs in cycles. The ovaries prepare an egg (oocyte) for release and the womb (uterus) prepares a lining to nourish the egg if it is fertilised. When the egg is not fertilised, the lining of the womb is shed and a woman gets her period (menstrual bleeding)
Answer:
when the thickened lining of the uterus endometrium leaves the body through the vagina. The lining of the uterus supplies a fertilised egg with nutrients, so if the egg isn't fertilised, then the lining is no longer needed.

Physiology is the study of life, especially the functioning of cells, tissues, and organisms. Physiologists are constantly striving to answer important questions in areas ranging from the function of individual cells to the interaction of human populations with the environment of the Earth, Moon, and beyond. Physiologists work in laboratories, libraries, the field, and space. For example, physiologists can study how a particular enzyme contributes to the function of a particular cell or organelle. Physiologists can use simple neural networks in snails to answer questions about the underlying mechanisms of learning and memory.
Physiologists can study the cardiovascular systems of animals to answer questions about heart attacks and other human diseases. Physiologists study how the body adapts to the extreme temperatures and environments encountered on Earth or the weightlessness of space flight, to see how life processes cope with these environmental stresses.

During division, the code for the protein cytochrome-C had the code for proline
changed to the code for leucine. This type of change in the genetic material is
known as a -
A. redundant mutation
B. frameshift mutation
C. point mutation
D. chromosomal mutation
Answer:
Point Mutation
Explanation:
The type of change described, where the code for proline is changed to the code for leucine during division, is known as a point mutation. The correct option is C.
A point mutation refers to a change in a single nucleotide base of the genetic material (DNA or RNA).
In this case, the change occurred at a specific position in the genetic code, resulting in the substitution of one nucleotide for another. This substitution led to a different amino acid being incorporated into the protein sequence.
Thus, based on the description provided, the correct answer is C. point mutation, as it involves the specific substitution of one nucleotide for another in the genetic code.

a scientist conducted an expirement to determine the effect of the enviroment on the color of fur of a himalayan rabit
The Himalayan rabbit's environment entirely determines the color of its coat.
How does the environment affect the coat color on the fur of a Himalayan rabbit?The color of newborn Himalayan rabbits is either white or light grey. Beginning at the age of four weeks and ending at six months, coloring the coat is a process. The temperature of the environment affects the color of the coat, which grows darker in colder climates and lighter in warmer ones. The Himalayan rabbit's hair turns black when it is subjected to subfreezing conditions. That area's fur finally turned black. The rabbit's newly grown fur will be black in color if the white fur is removed and the animal is kept at a low temperature. Considering this, it is clear that temperature affects the expression of genes that control this organism's fur color.

Other than their use in nucleic acid synthesis, which energy source is used uniquely for the synthesis of lipids?
a. atp
b. utp
c. gtp
d. ctp
e. none of these is unique to fatty acid synthesis
The correct answer is option d. CTP stands for Cytidine triphosphate.
In metabolic processes including the formation of glycerophospholipids, where it is used to activate and transfer diacylglycerol and lipid head groups, as well as glycosylate proteins, CTP functions as a coenzyme. Aspartate carbamoyltransferase, an enzyme required for pyrimidine production, is inhibited by CTP.The pyrimidine nucleoside triphosphate known as cytidine 5′-triphosphate (CTP) is similar to the more well-known ATP but uses cytidine as the base instead of adenine. It serves as a substrate in RNA production.A well-known example of feedback inhibition is the allosteric inhibitor cytidine triphosphate (CTP), which prevents an enzyme from initiating a step at the start of a biosynthetic pathway.CTP takes into account both the availability of materials and capacity, providing a more accurate picture of whether demand can be met within a specific time frame than ATP, which solely analyzes material availability and assumes infinite capacity resources.Learn more about Lipids here:
