Which of the following is true of the relationship between energy use and quality of life? a. Energy use has no relationship to overall quality of life. b. Generally, the quality of life is directly related to an area’s energy use per person. c. Increased energy use brings about a lower quality of life. d. A higher quality of life generally leads to a lower energy consumption.

Answer:

Option B, Generally, the quality of life is directly related to an area’s energy use per person.

Explanation:

There is a direct relationship between energy use and quality of life. The higher the energy usage per person , the higher is the quality of life.

For example - In developed countries like America, Germany etc, the amount of energy consumed per day per person is extremely high as compared to the amount of energy consumed per day per person in a developing or underdeveloped nation.

Thus, option B is the correct answer

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 .

Answer:

Question 2. The correct answer is "all of the above".

Question 3. The correct answer is "Physical"

Explanation:

Question 2. According to ecological terms, the life cycle of a population describes the different phases that a group of individuals go through from its growth to its death. The phases of the life cycle include: "growth", when the resources exceeded the number of individuals; "stability", when the resources are enough for the number of individuals; and "decline", when the resources are not enough for the number of individuals.

Question 3. The light is one of the most important physical environmental factors that affects a plant's growth. Light is considered a physical factor because is an abiotic factor that is inherent of the environment, such as sound and temperature.

Correct answer: A). 12

Sex cells are formed by the process of meiosis, and after the process of meiosis, the cell contains the half number of chromosomes as present in the parent. So if the parent has 24 pairs of the chromosome, then sex cells must contain 12 chromosomes, in order to form a diploid set of chromosomes after fertilization.

One difference between the pharynx and the larynx is that A. the pharynx contains the vocal cords, the larynx does not. B. the pharynx is above the epiglottis and the larynx is below it. C. the pharynx directly connects to the bronchi, the larynx is part of the trachea. D. only air passes through the pharynx, but both air and food pass through the larynx.

Hi Gary!

The answer would most likely be

B:
the pharynx is above the epiglottis and the larynx is below it.

It can't be A because the larynx is what contains the vocal cords.

It can't be C either because the pharynx doesn't directly connect to the bronchi. 

It can't also be D because air and food pass through the pharynx. Food does not pass through the larynx. 

Below is a diagram showing where the pharynx and larynx is located. You'll see how the pharynx is above the larynx, with the epiglottis in between making B the correct answer.

Hope this helped you understand more! Have a wonderful day! :D
