Which vitamin can be synthesized in significant amounts by humans and, therefore, may NOT be essential

Biology
1 answer:
Nadya [2.5K]3 years ago
5 0

Answer:

The correct ansqwer is- Vitamin D

Explanation:

Vitamin D is the vitamin that can be synthesized by the human body itself therefore it is not an essential vitamin for human beings. Human skin is the part that helps in making this vitamin in humans.

The natural form of vitamin D is vitamin D3 which is formed by the sunlight exposure on the skin. When we expose our skin in the sunlight the UV radiation penetrated our skin and converts provitamin D3 into pre-vitamin D3 then this previtamin can be isomerized into the natural form of vitamin D Which is vitamin D3. So the right answer is vitamin D.

A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr
alexandr402 [8]
In order to answer this, you will need to set up a Punett Square (I have attached a picture). 

Since Rr is the genotype of round seeds, we know that round must be dominant to wrinkled, and therefore represented by the allele, R.

Since rr is the genotype of wrinkled seeds, we know that wrinkled must be the recessive trait, and there represented by the allele, r.

Since the Punnett Square shows that the genotype ratio is 2Rr : 2rr, or simplified, 1Rr : 1rr, we now know that there is a 50% chance the offspring will have wrinkled seeds.

Two different species are discovered in the rainforest and their DNA sequences
Vanyuwa [196]

The similarity of 94% in their DNA sequence suggest that they have originated from a common ancestor and are closely related species.

Explanation:

The difference in DNA sequences in different species is due to the accumulation of genetic variation in the course of natural selection and evolution. Less is the difference in DNA sequences of two organisms the more related they are.

Genes determine the characteristics in an organism, and they are DNA sequences determining the protein to be formed. The similarity in DNA sequence of two species establish the evolutionary relationship among them.

Due to the genetic variation in species, the natural selection of the species had caused the evolution of the species adapted well to the environment.

which characteristic of water causes liquid water to form raindrops? A. water is less dense than dust particles B. water molecul
kondor19780726 [428]

Answer:

b. water molecules are strongly cohesive

Explanation:

Water is highly cohesive and clumps together into drops because of its cohesive properties. Water molecules attracting each other result in surface tension, which causes raindrops to form round beads as they fall on a surface.

Hope this helps!
