Lasting genetic similarities make the two bears biological sister species, more closely related to one another than to any others. ... But Ursus maritimus has also evolved to match its polar environment, growing a longer snout than brown bears' and larger, paddle-like paws, both of which aid polar bears in hunting seals.
It is called genetic engineering
Answer: The true statements about protein digestion and hydrolysis are;
1. Hydrochloric acid in gastric juices cause protein denaturation.
2. In small intestine trypsin attacks peptide bonds.
3.free amino acids are absorbed by the intestinal wall.
Explanation:
Protein digestion occurs in the duodenum and stomach and it is the breakdown of proteins to amino acids by action of Enzymes like trypsin, pepsin.
Protein is digested by the hydrolysis of carbon-nitrogen bond. Mechanical digestion of protein begins in the mouth and it continues in the small intestine and stomach.
Chemical digestion starts in the stomach where by hydrochloric acid in the gastric juice denatures the protein and convert pepsinogen to pepsin enzyme which convert the protein in food to peptides. Trypsin attacks the peptide bond that involves the carboxyl group which breaks it to polypeptide. Exopepdisases and dipeptidases breaks it down to amino acids. The amino acids released by protein digestion is then absorbed by the intestinal wall
<h2>Answer:</h2>
There is a whole history behind the evolution of homo sapiens. With regards to the data given here we can classify the species in upright human manner in this following way;
- H. Erectus
- A. Afarensis
- H. Neanderthalensis
- H. Sapiens
- A. Africanus
- H. Habilis
It is true that <span>convectional uplift goes through the process of adiabatic cooling.</span>
