Answer:

Hunger is a physiological desire to consume food.

Explanation:

Hunger is a physiological process controlled by the hypothalamus.

This helps in the secretion of different hormones that enhance the desire of hunger.

When someone eats carbohydrates rich food, insulin is secreted which uses the sugar. When there is no sugary food the insulin secretion is less.

When the person eats lipid food, another hormone will secrete called leptin. It helps in the release of energy to use in physiological activities.

Ghrelin is another hormone responsible for stomach cramps. When someone is hungry, the secretion of ghrelin is more to increase hunger. This is the very reason if a person awake at night he/she feels frequently hungry.

1. Muscles move tendons attached to bone by performing an action called _______.
REY [17]

1. Contraction

2. Actin

3. Tendons

4. Epidermis

5. Dermis

6. Acne

7. A nerve signal from the brain arrives at the intersection of the nerve and muscle cells and releases acetylcholine from the neuron. This triggers chemical changes in the muscle cell involving ions, including Ca2+. Calcium triggers the thick filaments, made of myosin, to attach to the thin filaments, made of actin, in the muscle cell, and the myosin pulls the actin toward the center of the muscle cell. ATP causes the release of the actin fibers, allowing the muscle to relax and the process to begin again.

Answer:

Reproductive isolation is the very factor that causes the development of what we call "species" according to the biological species concept. The reason cats and dogs are different species is that they can't mate, so we call them "reproductively isolated."

Explanation:

Genes with recombination frequencies(RF) of 50 assort independently and are not genetically links together but gene that have less than 50 RF are genetically linked.

The Linked genes included

a-d 12 c-e 26

a-g 4 d-g 8

b-c 10

b-e 18

Starting the order from the most tightly linked to the least

a-g 4, genetic distance is 4cM

d-g 8 genetic distance is 8cM

b-c 10 genetic distance is 10cM

a-d 12 genetic distance is 12cM
