Explained the effects of the use of antibodies in the control of a disease
Answer:
An antibody, also known as an immunoglobulin, is a large Y-shaped protein produced by B- cells and used by the immune system to identify and neutralize foreign objects such as bacteria and viruses.
Each tip of the “Y” of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision.
Though the general structure of antibodies is very similar, a small region at the tip of the protein is extremely variable, allowing millions of antibodies with different antigen binding sites to exist. This region is known as the hypervariable region.
Five isotypes of antibodies are found in different locations and perform different specific functions.
The base of the Y plays a role in modulating immune cell activity. This region is called the Fc region, and phagocytes may bind to it to initiate phagocytosis.
Antibodies that bind to surface antigens on a bacterium attract the first component of the complement cascade with their Fc region and initiate activation of the classical complement system.

Dimethylmercury is non polar volatile liquid that is lethal to animals. It’s structure is CH3-Hg-CH3. Predict the mechanism and timeframe of passage into cells for dimethylmercury based upon its chemical properties.
The dimetylmercury is a fat soluble compound thus it can pass into the cells easily through the lipid bi layer.
How does the compound work?We know that the compounds that are water soluble would have to be ionic. It is very vital that we start the discussion from here because we ought to know that the compounds that are covalent would not be found to dissolve in water.
On the other hand, we have to recall that the entrance of the cell is a nonpolar region as that area is mostly filled with the fats that we can find around there. It then means that the compounds that may be able to pass into the cell very freely has to be the compounds that are fat soluble based on its chemical properties.
We must recall that Dimethylmercury is non polar volatile and as such it can be able to pass through the membrane and enter into the cells.

Why are gametes the only haploid cells in your body?
Gametes are the only haploid cells in the human body because they are the cells involved in sexual reproduction, which requires the combination of one set of chromosomes from each parent to form a new individual. The rest of the cells in the human body are diploid and do not participate in sexual reproduction.
Gametes, which are also known as sex cells, are the only haploid cells in the human body because they are the cells that are involved in sexual reproduction. Haploid cells have a single set of chromosomes, while diploid cells, which make up the majority of cells in the human body, have two sets of chromosomes.
During sexual reproduction, gametes from each parent combine to form a new individual. The gametes from each parent contribute one set of chromosomes to the offspring, so that the resulting diploid cells in the offspring have two sets of chromosomes, one set from each parent.

Answer:
Human gametes are haploid (n) as they are formed by meiosis during the process of gametogenesis.
Explanation:
Haploid can be described as a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells.
Haploid gametes lead to the fusion of male and female gametes, by which a diploid zygote is formed and the number of chromosomes remains the same in the progeny.
In humans, gametes are haploid cells that contain 23 chromosomes.
