Ice float on water due to increased density and when it is melted into water due to being equal to its own weight as well as the molecular level.
what is density?Density can be referred as the mass of a unit volume of a substance. The formula for density is represented by d = M/V, here d is density, M is mass, and V is volume.
density can be commonly represented in units of grams per cubic centimeter and it can be expressed as kilograms per cubic meter .
Density define how different materials interact each other, For example Wood floats in water because it has a lower density, while an anchor sinks because the metal has a higher density.
density has a lots of application and it can be applied in pipe design, shipbuilding, helium balloons, weight distribution in the aero plane, and the fact that ice floats on water.
density is used in determination of an object which float on water and diving of submarines are due to their density difference.

How does a person's response to stress change throughout all three phases of Selye's general adaptation syndrome? Answer: In the first phase of the general adaptation response (the alarm phase), the body reacts to a stressor with an alarm reaction. A person may notice a quickening heart rate and an increase in breathing and energy. In the second stage of the general adaptation response (the resistance phase), the body releases hormones to stabilize body, but the body still remains at high alert as physiological responses remain elevated. Finally, the body reaches exhaustion phase if the stress continues. In this phase, the person has used all resources and has nothing more to use to cope with the stressor. It is during this stage that the person's emotional and physical health begins to decline.
Answer:
true
Explanation:
It is during this stage that the person's emotional and physical health begins to decline. The given statement is True.
What is Adaptation?The biological process through which organisms adapt to new surroundings or modifications in their current environments is known as adaptation in evolutionary theory.
Even while adaptation was a topic of discussion among scientists before the 1800s, Charles Darwin and Alfred Russel Wallace did not create the theory of natural selection until then.
Wallace and Darwin both went beyond basic adaptation when formulating the notion of evolution by natural selection by describing how organisms adapt and evolve.
Therefore, It is during this stage that the person's emotional and physical health begins to decline. The given statement is True.
