Lunar phases are basically the different positions of the moon that we see throughout its whole cycle, from new moon to full moon, back to new moon. Eclipses, though are more rare phenomena. These occur when the sun, moon, and earth line up at a specific position.

Asteroids are usually dense bodies, with many different formations on their surface. They are also believed to be the largest source of precious metals on our planet.

Comets are bright clouds of gas surrounding a center nucleus that speed toward the sun and heat up at the same time. They contain dust, ice, carbon dioxide, and other gases. As the comet soars toward the sun, the radiation pushes dust particles back, forming the tail they are known for.

Why does increasing soil salinity have adverse effects on plant cells?

borishaifa [10]

Ezywhen salinity in soil increases the soil becomes hypertonic when compared to cell sap.the movement of particles from a lower concentrated solution to a higher concentrated solution is callede osmosis. in general conditions cell sap is at higher conc. than surrounding media. this allows water and minerals to enter the plant. but when soil is at higher conc. i.e., when its salinity increases the process becomes reversed can you imagine its consequenses?

Dilated pupils, inhibited digestive activity, increased respiratory rate, and release of glucose from the liver are all signs of

Nataly_w [17]

Answer:

C. the sympathetic division of the autonomic system.

Explanation:

The sympathetic nervous system is one of the divisions of the autonomic nervous system that controls involuntary body functions in the body. The sympathetic nervous system is said to stimulate the fight-or-flight response of the body when the body senses threat, or is exposed to a stressor. These fight-or-flight responses are generated in the body in form of physiological changes in order to put the body at top alert to focus on dealing with the stressor.

Physiological changes that are stimulated by the sympathetic nervous system as fight-or-flight responses include dilated pupils, inhibited digestive activity, increased respiratory rate, and release of glucose from the liver, which are all stated in the question. It is the sympathetic division of the autonomic nervous system that controls all these activities.
