Vagus nerve
Cranial nerves supply sensory and motor information to structures of the head and neck, controlling the activity of this region. Only the vagus nerve extends beyond the neck, to innervate thoracic and abdominal viscera.
Answer:
A
Explanation:
Due to mutations in DNA that accumulate at a fairly constant rate , the reduction in melting temperature for hybrid DNA between two mammalian species, it is used to predict how long those species have been since divergence.
Hence option A is correct.
Answer:
Dense Regular Connective Tissue
Explanation:
Dense regular connective tissue make up ligaments and tendons. They are made up of collagen fibers that are tightly or densely packed, parallel to each other, giving off a "wavy-hair" look. They are more resistant to stretching (although it allows some) because they are made up of more collagen fibers than loose connective tissue.
Look at the picture attached if you want to see what they look like up close.

Answer:
<h2>Incomplete dominance</h2>
Explanation:
As given here;
Two pure line of four-o'clock plant, one having red flower and other having white flower, when they are crossed, they produce all pink progeny.
So, lets red as RR and white as rr
Cross between RR and rr
Here all offspring are Rr ( Pink ).
It's the result of incomplete dominance, in complete dominance the offspring is the intermediate of both the parents.
F2 generation:
As cross between Rr and Rr
progeny are: RR, Rr, Rr, rr
RR =red
Rr= pink
rr= white
So, red: pink: white = 25:50:25
