Which of the following is a benefit associated with the use of energy producing technologies excluding the burning of fossil fuels? a. reduced water use b. reduced air pollution c. reduced habitat loss d. all of the above

The correct answer is option D

Excluding the burning of fossil fuels which causes air pollution, the benefit that is associated with the use of energy production is reduced water, reduced air pollution and reduced habitat loss.

The other alternatives that is used to produced energy uses reduced amount of water and and they do not release harmful gases into the environment.

As it is renewable sources of energy it does not cause any loss to the environment. No deforestation and hence, no habitat loss.

Which statements describe a good hypothesis? Check all that apply. A good hypothesis is based on one’s personal opinion. A good hypothesis can be tested. A good hypothesis leads to a test with measureable results. A good hypothesis does not always have to be based on prior knowledge or research. A good hypothesis provides a possible explanation to answer a scientific question.

Answer:

The correct statements are b, c, and e.

A hypothesis is defined as a tentative or proposed explanation for the occurrence of any phenomenon.

It is usually based on a very less number of pieces of evidence and provides the first step for further classification.

The hypothesis must be testable so that it can be accepted or rejected on the basis of scientific methods.

Thus, the correct statements are b, c, and e.

There are several properties of water that make Earth a suitable environment for life, including water's high boiling point and high heat capacity. Which best explains why this characteristic of water is important for marine life? A.) It allows water to remain in its liquid form even at relatively high temperatures. B.) It allows water to vaporize easily, powering the water cycle. C.) It allows water to be denser, making it easy for living organisms to move through. D.) It allows water to resist freezing and thawing cycles.

Answer: D.) It allows water to resist freezing and thawing cycles.

The ability of the water molecule to absorb and retain heat is called as heat capacity of water, because of this property the temperature of water remains the same for long, irrespective of the external environment. It allows water to resist freezing and thawing cycles because water molecules will resist change in it's temperature. This temperature regulation will prevent instant heating and cooling, hence, will provide suitable environment for the survival of marine organisms.

If you had to choose one gland or resulting hormone to live without which one would it be and why? Which gland or resulting hormone do you think serve the most important function and why? Include example from personal experience or a scenario.

Answer:

It would be thyroid gland, as post thyroidectomy an individual can lead a normal life. The thyroid gland is accountable for generating two essential hormones, that is, triiodothyronine and thyroxine. These hormones monitor the metabolism, however, with the application of medications like levothyroxine one can substitute the functioning of the thyroid gland and may lead a normal life.  

The pituitary gland is the most essential gland in the body, it is also known as the master gland as the hormones produced by pituitary gland also monitor the functions of other endocrine glands.

The idea that no energy is lost when gas molecules hit the walls of a container or each other is explained by which statement of the kinetic molecular theory? Gases are made up of molecules which are relatively far apart. The molecules are in motion at high speeds. The molecular collisions are perfectly elastic. Increase in temperature increases the kinetic energy of the molecules.

The right option is; The molecular collisions are perfectly elastic.

The kinetic molecular theory is a theory that describes the experimental observations about the behavior of gases. This theory is based on five postulates, or assumptions. The idea that no energy is lost when gas molecules hit the walls of a container or each other is explained by the fourth statement (postulate) which states that molecular collision (between gas molecules or with the walls of the container) is perfectly elastic and it does not involve the loss of any energy .
