Why is it good for aquatic organisms that live in cold climates that ice floats?
Zielflug [23.3K]

Answer;

-The less dense, the more the ice will float, allowing animals to stay afloat and not in the water

Explanation;

-When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.

-This means that ice floats on water and that lakes freeze from the top down to the bottom.This is vital for animals that live on ice, as their habitats would be greatly reduced or not exist at all if ice sank.

Marie's pulse, breathing rate, and mental alertness have suddenly increased. it is likely that marie is experiencing the:
NISA [10]
Marie is experiencing the: Sympathomimetic effects (fight-or-flight state).

The sympathetic nervous system is a component of the autonomic nervous system, managing the activity of visceral organs and the automatic functions of the body, such as breathing or beating of the heart. The sympathetic nervous system is involved in many unconscious physiological activities through two neuromodulators of the catecholamine family: adrenaline, but especially norepinephrine (fight-or-flight hormones).
* It accelerates the metabolism and is activated for example in case of danger or fear, to prepare the individual to escape.
* It affects the cardiovascular system: it increases the heart rate and induces peripheral vasoconstriction, causing an increase in blood pressure.
* At the digestive level, it slows the muscular contractions of the intestines but promotes the release of glucose by the liver.
* It also has a bronchodilator effect, that is to say, it causes the increase of the diameter of the bronchi.
