It is recommended that one to consume from 10 to 35 percent of your total daily calories from protein. According to RDA the current adult dietary intake they recommend for protein is 10 % to 35%. From the dietary reference intake about 0.8 grams of protein per kilogram of body weight, or 0.36 per pound, which averages to about 56 grams per day for men and about 46 grams per day for women.
Image result for How did the results prove the semiconservative model of DNA
The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. Although Meselson and Stahl did their experiments in the bacterium E.
<span>The correct answer is "Sudden changes in the somatic cells of organisms play a key role in the process of adaptive evolution". Adaption in evolution is caused by sudden gene mutations that affect an organism's offspring and give it - potentially - a better chance of survival. For example, a giraffe who passed on a mutated gene for a slightly longer neck to its offspring gave its offspring a better chance of reaching untouched food, and thus a survival advantage.</span>
An evolutionary tree can also be called a phylogenetic tree, or a just a phylogeny, and phylogenetics is the study of determining evolutionary relationships, or patterns of descent of organisms.
B Physical separation of populations prevents interbreeding and mixing of gene pools.
Explanation:
Geographic isolation means two populations are unable to reproduce with one another. This means that over time, the variation in the gene pool will be different for one group compared to the other, and the species will genetically diverge from one another. resulting in speciation.
