Answer:
The understanding of evolutionary processes has helped the scientist in the field of artificial selection.
Explanation:
Artificial selection is the intentional breeding of plants and animals. It means the same thing as selective breeding and is an ancient method of genetic engineering. Selective breeding is a technique used when breeding domesticated animals such as dogs, pigeons and cattle. Thoroughbred racehorses are the one such example of artificial selection of animals.The meats we eat are the result of careful selective breeding of cows, sheeps and chicken.
The breeding of plants and animals to produce desirable traits. Organism with the desired traits such as size or taste are artificially mated or cross pollinated with the organisms with the similar desired traits.
It penetrates the skin and can cause mutations.
Answer:
It helps keep the mouth clean, digest food, and keep gums and teeth healthy.
Explanation:
hope that helps.
It might not be a good idea as nitrogen may be needed by plants in several cellular processes and eliminating nitrogen uptake might severely impair these functions if there are no alternatives to these pathways
Answer and Explanation:
Bovine pancreatic trypsin inhibitor (BPT I) is a small globular protein and it inhibits the proteolytic enzymes like trypsin. BPTI is composed of ∝ helices, β sheets and 3 disulfide bonds. Due to these BPTI is a stable protein in its tertiary structure. It is almost inert to denaturation by urea and exhibits denaturation below 100 degree, only in highly acidic solutions. When all the disulfide bonds in BPTI are reduced, the protein is unfolded at room temperature and can reform three correct S-S pairings in native confirmation. if the 6 cysteine residues are reduced and unfolded in urea, the re-oxidation would yield 3 pairs with probability of first pair with 5, second pair with 3 and the third pair with 1 cysteine residues. Therefore, 5 x 3 x 1 = 15 combinations are possible accounting for 7% of protein refolding.
