Answer:
A. Primary dimensions are less changeable, while secondary dimensions can change and are less visible.
Explanation:
The differences between primary and secondary dimension of diversity are as follows -
A) Primary Dimension
a) Primary dimension are those which are salient and hence they cannot change
b) Some common examples of primary dimensions are - ethnicity, sexual orientation, ethnicity, gender, race, physical abilities/qualities, age etc.
A) Secondary Dimension
a) Secondary dimension are not only limited to specific features and hence they can change with time.
b) Some common examples of secondary dimension are - geographic location, marital status, parental status. work experiences, educational background, income,military experience, religious beliefs, etc.
Hence, option A is correct
Glucose, amino acids, lipids and glycerol.
Explanation:
Carbohydrate is broken into glucose molecules
protein is broken into amino acids
Lipid is broken into fatty acids and glycerol.
Starch present in the food is broken to glucose molecules to yield energy.
Protein is digested in stomach by the action of pepsin, trypsin and chymotrypsin.
Glycosidic bonds of starch is broken down by salivary and pancreatic amylase enzyme.
fat is acted upon by lipase enzymes from pancreatic and intestinal juices.
these are broken into smaller units so that gets absorbed by blood and carries throughout the body.
Answer: In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. The honeycreepers dispersed from one founder species, and evolved in response to natural selection based on different food sources in their isolated habitats provided by water. Seed-eating birds evolved thick, short beaks.
As population and density and competition increase, the death rate goes along with the positive curve so death rate increases.
