In genetics, alleles refer to different versions or variants of a gene that occupy the same position, or locus, on a chromosome. Genes that carry contrasting inheritance factors are called alleles.
Alleles can have contrasting forms or inheritance factors, meaning they may code for different traits or variations of a particular characteristic.
For example, let's consider a gene for eye color. One allele may code for blue eyes, while another allele at the same locus may code for brown eyes. These two alleles are contrasting in terms of the trait they represent, in this case, eye color.
Homozygotes and heterozygotes are terms used to describe individuals with specific combinations of alleles. Homozygotes have two identical alleles at a particular locus (e.g., BB for brown eyes or bb for blue eyes), while heterozygotes have two different alleles at the same locus (e.g., Bb).
Therefore, genes that carry contrasting inheritance factors are called alleles.

c. predictable
d. related to human activities
The events that lead to genetic drift are random. Genetic drift is a random change in the allele frequencies of a population. It is caused by chance events, such as the founder effect or the bottleneck effect. Hence option B is correct.
These events can cause some alleles to become more common in a population, while other alleles become less common.
Genetic drift is not always caused by natural disasters. It can also be caused by human activities, such as migration or selective breeding. However, the events that lead to genetic drift are always random.
Therefore, option B) Random is correct.

Answer:
The correct answer is B-cells
Explanation:
There are two types of lymphocytes B- lymphocytes and T- lymphocytes. B lymphocytes or B cells when interacts with the antigen with its B cell receptor it differentiates into two cell memory B cells and plasma B cells.
Plasma B cell is responsible for secreting various antibodies and these antibodies bind to the epitope region of antigen and helps in opsonization and killing of antigen. Memory B cell helps in generating quick immune response when that antigen comes again in the body. Therefore the correct answer is B cells.
b. Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gases
c. Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits.
d. Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.

Explanation:
No, Bill did not follow the safe lab procedures.
Some of the safe lab procedures are as follows:
When a test tube is broken, you immediately check yourself first and ensure that it can not make any sort of injury to yourself. Then, inform the teacher or manager of the laboratory about this incident.
Then gather all sorts of pieces of broken test tubes carefully with the help of a broom, and placed them separately instead of using the same garbage can that consists of other waste compounds or substances in the laboratory.
Therefore, it can be estimated that Bill did not follow the safe lab procedures.
