The correct answer is binary fission.
It is the process by which prokaryotic cells produce new cells that are genetically similar to the parent cell. It is an asexual kind of reproduction.
it occurs in three main steps
1. DNA replication to make a set of two chromosomes.
2. Chromosome segregation where the two chromosomes separate.
3. Cytokinesis, a process in which a new plasma membrane begins to form in the center of the cell followed by the splitting of the cytoplasm into two, and two daughter cells are formed which are genetically similar to each other and to the parent cell.
(1) modification of genes in body cells
(2) modification of genes in sex cells
(3) increased reproduction among individuals
with identical chromosomes
(4) recombination of genes in cells reproducing
by mitosis
Evolution in sexually reproducing species occurs as a result of modification of genes in sex cells. Genetic variation through mutations and genetic recombination during meiosis leads to offspring that are genetically different from their parents, providing the basis for natural selection and evolution.
In a sexually reproducing species, evolution occurs as a result of modification of genes in sex cells. Sex cells, or gametes, such as sperm and eggs, carry genetic information that is passed on to offspring. Genetic variation can arise through mutations or through the process of genetic recombination during meiosis, resulting in offspring that are genetically different from their parents. This genetic variation provides the raw material for natural selection and evolution.

B. gel electrophoresis
C. karyotypes
D. haplotypes
Answer:
The correct answer is option A. restriction enzymes.
Explanation:
Restriction enzymes or restriction endonucleases are enzymes that identify a particular DNA sequence, knowns as restriction site, and cuts the DNA within or adjacent to restriction site.
Restriction enzymes also known as biological scissors because of their ability to cut DNA at a specific sequence.
EcoR I, isolated from the bacterium Escherichia coli, is a restriction enzyme that restricts DNA between the G and A on each strand in a particular DNA sequence.
Thus, The correct answer is option A. restriction enzymes.
B. It has a natural ionic charge of +4.

Answer: C. It can bond with other carbon atoms that are bonded to other molecules.
B.tetrads
C.diploids
D.chromosomes
Hi,
Which consist of sperm cells and egg cells?
A.gametes
Answer:
a. Protein is a major component of body structures.
Explanation:
Proteins are large, complex molecules made up of amino acids. They play a crucial role in the structure and function of our bodies. Here's why option a is the correct answer:
a. Protein is a major component of body structures: Proteins are the building blocks of tissues in our body, such as muscles, bones, skin, and organs. They provide structural support and help maintain the integrity of our body.
b. Supplies 9kcal per gram: This statement is incorrect. Protein supplies 4 calories per gram, not 9. It is carbohydrates and fats that provide 9 calories per gram.
c. Functions as a solvent: This statement is incorrect. Proteins do not function as solvents. They are involved in various functions such as enzyme catalysis, transport of molecules, immune response, and cell signaling, but not as solvents.
d. Is the body's main source of fuel during physical activity: This statement is also incorrect. While protein can be used as an energy source, it is not the body's main source of fuel during physical activity. Carbohydrates and fats are the primary sources of energy during physical activity.
In summary, protein is a major component of body structures and plays a vital role in maintaining the structure and function of our body.
