B. 68% of the molecules have speeds between 450 meters/second and 550 meters/second.
C. 50% of the molecules have speeds between 450 meters/second and 550 meters/second.
D. 34% of the molecules have speeds greater than 550 meters/second.

Answers

Answer 1

Answer: This information best supports the conclusion that 68% of the molecules have speeds between 450 meters/second and 550 meters/second. The answer to your question is B. I hope this is the answer that you are looking for and it comes to your help.

Answer 2

Answer:

68% of the molecules have speeds between 450 meters/second and 550 meters/second is correct option.

How speed of the gases are calculated?

Nitrogen's rms speed will be (4 / 28) = 0.378 of helium's rms speed, yielding a speed of 0.378 1370 m s–1 = 517 m s–1. Now the factor is (4 / 44) = 0.301, resulting in a speed of 0.301 1370 m s–1 = 413 m s–1.

This data best supports the hypothesis that 68 percent of the molecules travel at speeds of 450 to 550 meters per second. B is the solution to your query.

What will the continued depletion of the ozone layer most likely cause?

Answers

Answer:

A. an increase in skin cancer among humans

Explanation:

The ozone layer is a part of the stratosphere that absorbs most of the Sun's ultraviolet(UV) radiation.The ozone layer contains a lot of ozone present in it and it serves as a shield. The radiations are harmful to the body and pose serious health risk when humans are exposed to them.

Such risks include cancer of the skin due to the skin being the part of the body at a greater risk of exposure.

Organisms need nutrients in order to:a. utilize hydrogen and oxygen.
b. carry out essential life functions.
c. recycle chemical compounds.
d. carry out nitrogen fixation.

Answers

The answer is letter B.

Organisms need nutrients to carry our essential life functions. These nutrients provided the necessary energy to power the different processes of the cells of the body. As a result, essential life functions are easily performed. A deficiency in one or may different nutrients in the body could result to different diseases or disorders. The main source of nutrients of the human body come from different food sources (e.g. plants, animals). These foods when broken down in the body release chemicals that are necessary for many internal processes.

Final answer:

Organisms primarily need nutrients to carry out essential life functions, such as growth, repair, and maintaining biological processes. Nutrients are used to produce energy, build and maintain tissues. Certain organisms can also use nutrients to recycle compounds and carry out nitrogen fixation.

Explanation:

Organisms need nutrients primarily to carry out essential life functions. These functions include growth, repair, and the maintenance of basic biological processes. Essential nutrients, which must be obtained from the diet, are used to produce energy, build and maintain tissues, and regulate bodily processes.

Nutrients such as carbohydrates, proteins, and fats are utilized by cells in a series of metabolic reactions that provide the energy required for these vital functions. Some organisms can also utilize nutrients to recycle chemical compounds and carry out nitrogen fixation. However, these processes are generally specific to certain types of bacteria and plants.

in order to use the Hardy-Weinberg equation to calculate genetic variations in a population which of the following conditions must exist in the population

Answers

Answer: All organisms must reproduce.

Explanation: Trust me G

APEX. Just trying to help people out who also have this question.

Population of living creatures or living organisms.

Because what can reproduce is a living creature/organism.

Further explanation

The Hardy-Weinberg Principle states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence. These influences include perfect pairing, mutation, selection, genetic drift, gene flow, and Meiosis steering.

The seven assumptions underlying the Hardy-Weinberg equation are as follows:

Such organisms are diploid
only reproduce sexually
generation that does not overlap
random marriage
infinite population size
same frequency alleles in both sexes
no migration, mutation or selection

The scarlet cup fungus (Sarcoscypha coccinea) obtains its nutrition from decaying wood by releasing digestive enzymes into the wood and absorbing the digested products.I. Autotroph
II. Heterotroph
III. Saprotroph
A. III only
B. II and III only
C. I and III only
D. I, II and III

Answers

II and III only. The fungus is a heterotroph, since it's not making it's own food, but it's also a Saprotroph (since it externally digests dead organic materials; saprotrophs are a special subset of heterotrophs).
