Choose the correct order of steps for the synthesis of Vitamin D.

Biology
1 answer:
n200080 [17]3 years ago
4 0

Answer:

The correct answer will be option-

1. UV light strikes the skin and converts a steroid molecule into an inactive form of vitamin D.

2. Inactive vitamin D is transported to the liver where it is modified.

3. Vitamin D is activated under the influence of PTH.

4. Inactive, chemically altered vitamin D is transported to the kidneys.

Explanation:

Vitamin D is a fat-soluble metabolite which helps maintain the health of the bone by maintaining the calcium homeostasis.

The vitamin D is synthesized mainly in the liver and kidney from the biologically inactive precursor of vitamin D called ergocalciferol and Cholecalciferol.

The inactive vitamin is synthesized in the skin when the skin is exposed to UV rays.  The UV rays convert the 7-dehydrocholesterol, a steroid molecule to Vitamin D3, This inactive vitamin is then transported to the liver where it is converted to 25-hydroxyvitamin D.

This vitamin D form is further metabolized in the kidney controlled and regulated by the Parathyroid glands.

9. What are mutations, and how do they increase the genetic variation within a species?
leva [86]

Mutations are changes that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.

They increase the genetic variation within a species because they can create entirely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis which reshuffles alleles within an organism's offspring.

Explanation:

The following are the two considerations demonstrating that there would be less biodiversity than the tropical areas in the Mediterranean climate as well as polar areas.

  • The first reason is all tropical areas experience drastic temperature variation.
  • The second reason is early in the earth's history, the northern latitudes are inhabited.

A population of large predators in an ecosystem has been trapped and removed from the area. How would this event most likely cha
Kay [80]
When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it. This is known as a trophic cascade. The results of these trophic cascades can lead to an ecosystem being completely transformed. The impacts trickle down through each level, upsetting the ecological balance by altering numbers of different animal species, until the effects are finally felt by the vegetation.
