Answer:

c. reabsorbing hydrogen

Explanation:

In this scenario, the individual's kidneys will do all of the following except for reabsorbing hyrdogen. This is because, in a scenario like this where the body pH levels decline the kidneys begin to secrete hydrogen, they do not reabsorb it. It is this process of acid elimination that ultimately causes the body's pH levels to begin rising and restoring themselves to normal. Therefore the answer to this question is c.

. Which graph best shows the general relationship
Andre45 [30]

The graph that best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas is B.

<h3>What is kinetic energy?</h3>

Kinetic energy is the energy that an object or particle has as a result of its motion. When work transferring energy, is done on an object by applying a net force, the object accelerates and goes under kinetic energy.

The missing graphs are attached as image.

The average kinetic energy of gas molecules is

K=\frac{3}{2} k_{B}T

K∝T

So as per above equation, K-T graph is a straight line having a finite slope and passing through the origin.

Thus, option B is correct.

When two species occupy the same niche in an ecosystem, the result of the competition is that one species will either have to mo
patriot [66]

Biodiversity decreases, and the overall health of the ecosystem decreases.

Answer: Option D

<u>Explanation:</u>

In a niche when two different species occupy a niche competition arises between them. In due course both the species fight for existence and nature selects the best adaptable one to win. The other species either reduces in its population or gradually in struggle for existence they deteriorate and die.

Hence a decrease in bio diversity happens here due to natural selection. If the biodiversity is decreased in a particular niche it affects the growth of different species which in turn affect the whole ecosystem resulting in decrease of the overall health in an ecosystem.

Give some examples of biodiversity you find in your ecosystem.
artcher [175]

Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the naked eye.
