<span>The correct answer is A, B and D. Biogeochemical cycles are central to the ecology of earth system. They make the essentail elements accessible and available for the organisms, and maintain their levels, so that the ecology is ot disrupted. The elements move through abiotic and biotic factors, in these cycles, and a state of equilibrium is maintained n the ecosystem. The carbon dioxide levels are responsible fr the temperature of the earth. If Carbon cycles would not have existed, then there would have been a disruption in maintaining the global temperature. Biogeochemical cycles basically continuously recycles the essential materials, for sustaining the life-forms.</span>
Answer:
6,25%
Explanation:
Considering that the couple has a trait of sickle cell anemia, we know that both are heterozygous for the disease (Aa) and therefore can have children with the following genotypes:
Parents: Aa X Aa
Children: AA(A x A), Aa(A x a), Aa (a x A) and aa(a x a)
Knowing that sickle cell anemia only occurs in homozygous individuals, the probability for children to have the disease according to each crossing is:
A x A = 1/4 = 25%
A x a = 1/4 = 25%
a x A = 1/4 = 25%
a x a = 1/4 = 25%
The probability of forming each homozygous child (aa) is 1/4 or 25%. Since they are two children, the probability of both having sickle cell anemia is calculated by multiplying the probability of each, so:
1/4 × 1/4 = 1/16 = 0.0625 = 6.25%
It is concluded that the probability of a heterozygous couple for sickle cell anemia to have two children with the disease is 6.25%.
Diabetes type 1 is a chronic illness also referred to as juvenile diabetes or insulin-dependent diabetes.
<h3>
What is type-I Diabetes?</h3>
- The pancreas produces little or no insulin in this situation. Insulin is a hormone that the body utilizes to let glucose (sugar) into cells where it can be used to make energy.
- Type 1 diabetes may be brought on by a variety of factors, including genetics and some viruses. While type 1 diabetes typically first manifests in childhood or adolescence, it can also strike adults.
- There is still no cure for type 1 diabetes, despite much research. The goal of treatment is to prevent problems by controlling blood sugar levels with the use of insulin, food, and lifestyle changes.
