I think it was <span>Rosalind Franklin who discovered what DNA was made up of.
</span>James Watson and Francis Crick discovered the double helix shape of DNA and also created a 3d model of it, so it's not B nor C.
To my understanding (you should double check) the answer is D
Answer:
The loss of fur is a protection mechanism for the epithelium that covers us, over the years this method of protection was replaced by the protection provided by melanocytes with their melanin, therefore people who had a low presence of melanin could not survive in the evolution.
Explanation:
The presence of melanocytes and melanin in the skin is what protects it against ultraviolet radiation, over time the human being was affected by solar radiation, thus being one of the causes of bipedalism.
In those humans where melanin is defective or a small number of melanocytes are more predisposed to suffer epithelial pathologies today.
Human evolution then led to hair loss and increased epithelial tonality, causing those who could not have this phenotypic quality to be extinct or deceased.
It is supposed to flow through so heterotrophs(like humans etc) can gain energy from plants(autotrophs) which other animals gain energy from them eating each other which follows the food chain. Which keeps the food chain and life in order, by giving energy for work and life to sustain.
Answer:
They are all carbohydrates.
Explanation:
Homo polysaccharides include starch, glycogen, and cellulose (same type of sugar-all made of glucose).
1- Amylose and Amyloprotein are the components of starch. Amylose is a branched chain with alpha 1–4 and alpha 1–6 at the branch point, whereas Amylopectin is a linear chain with alpha 1–4 and alpha 1–6 at the branch point.
2- Glycogen is created by forming a branched chain from glucose at alpha 1–6. It has a lot of branches.
3- Cellulose is a linear chain of glucose molecules with beta bonds.
Starch and glycogen serve as short-term energy stores in plants and animals, cellulose found in plant cell wall only.
I believe the correct answer is natural selection.
Natural competition and the fight for “survival of the fittest” is what pushes diversity the most.
