Which of the following statements about tolerance rang is true?

Option A

Explanation:

Hi Jacobpalacios! How are u?

Here are the justifications of my choice:

A.TRUE. Organisms have different ranges of tolerance depending on the type of organism and the species (microorganisms, fungi, plants, animals or even humans have different ranges of tolerance, for example at temperature). In other words, different types of organisms have different tolerance ranges for the same factor.

B.FALSE.  The tolerance range represents the number of individuals in a population that lives under a certain range of a given factor (no the ecosystem in general). For example, we can know the number of individuals who tolerate a certain concentration of oxygen.

C.FALSE. The tolerance range is affected by abiotic factors (environmental conditions), not biotics. For example, temperature, oxygen, acidity of the environment, etc.

D.FALSE. Most individuals need a minimum percentage of water for their organisms or organelles to function. Therefore, the availability of water will be a factor that impacts the tolerance range of an organism.

I hope I've been helpful!

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
