When exercising is when the lungs work the hardest because you're using a lot of muscles and are running around and are using force in your body so the lung works really hard to make sure the body gets enough air while working out.

1. How did you revise your sequence from your initial idea ? Explain how you decided on the sequence. For the Natural Selection
liberstina [14]

Natural selection is the idea that  organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring.

<h3>What is natural selection?</h3>

The question is incomplete but I will try my best to explain the idea of natural selection.

The term natural selection refers to the idea put forward by Charles Darwin that organisms that posses favorable traits that enable them to survive in their environment are the ones that live long enough to pass on these traits to their offspring. This is also called the survival of the fittest.

Which of the following statements is true?
mafiozo [28]

Answer:

The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.

Explanation:

The kidneys are the organs that control, for example, <u>the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. </u>These organs are also key to <u>eliminate the toxins from the body. </u>

The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.

The kidneys <u>do not regulate blood glucose</u>. That is the job of the pancreas through two hormones called insulin and glucagon.

The kidneys <u>do not remove nitrogenous wastes</u> (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.
