Select the correct answer from each drop-down menu. sickle cell disease is passed on from parent to offspring. sickle cell disease is an disease. some carriers of the disease exhibit increased resistance to malarial parasites. this resistance is a mutation

All the statements of the question are correct.

Sickle cell disease is an autosomal recessive disorder that is characterized by formation of defective hemoglobin protein, which results in sickle shaped RBC ( red blood cell).

This disease is caused by mutation in the gene that is responsible for the protein hemoglobin ( which transport oxygen throughout body).

It is inherited by the offspring when both the mutated copy of genes ( one from each parent) are passed to him.

Carriers of the disease exhibit increased resistance to malarial parasites by controlling the level of free haem in the blood ( through enzyme heme oxygenase that produces a toxic carbon monoxide gas). The resistance thus developed, is a mutation.

Therefore, all the statements in the given question are correct.

Sickle cell disease is passed on from parent to offspring. Sickle cell disease is an inherited  disease. Some carriers of the disease exhibit increased resistance to malarial parasites. This resistance is a  beneficial  mutation.

Explanation:

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
