Answer:
Option D, Gastric Juices
Explanation:
The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.
Hence, gastric juice does not belong to second line of defense.
Thus, option D is correct.
Answer:
I think it’s c because the crystals look quite large and doesn’t seem squashed

Explanation:
This is known as kin selection.
Behaviors which increase the reproductive success of genetic relatives increase the inclusive fitness of the individuals. If you have discussed Hamilton’s rule, recall that an allele will rise in frequency in the population over time if rb > c. Where r is the relatedness coefficient (to the relative benefitting from the behavior), b is the additional offspring that the relative has, and c is the personal offspring that are lost.
Answer:
The correct answer is - B. disruptive selection.
Explanation:
Adaptive radiation is a type of genetic drift that relatively fast evolution of many species from a single common ancestor which means there is a big drift in a very small time.
Disruptive selection is a type of natural selection that shows phenotypes (individuals with groups of traits) of both extremes but has very few individuals in the middle. An example of this type is the evolution of mammals after the extinction of dinnosaurs.
