The fish shown here is normally found in a pond but is being studied in an aquarium. The amount of water and salt intake and exc

retion is measured as the fish maintains homeostasis. What scientific

Based on the information in the question, we can infer that the question being asked is most likely "<u><em>What mechanisms do fish use to maintain homeostasis in salt-water environments</em></u>?".

<h3>What is homeostasis?</h3>
  • Homeostasis is a series of regulatory processes by which an organism <em><u>maintains core values (or range of values) necessary for everyday life.</u></em>

<em><u /></em>

<h3>How to test the question</h3>
  • The question is in the form of a hypothesis.
  • This means that the scientist must first propose a possible solution to the question.
  • Then, the scientist will make observations based on this question.
  • In this case, it would seem the scientist has placed the fish into an environment <em><u>that differs from its natural habitat, in order to observe how the fish maintains homeostasis. </u></em>

Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.

if a cell increases the activity of its actin severing proteins, will it lead in the short term to more or less actin polymer ma
marta [7]

More polymer will form if the concentration of free actin monomers is higher than the Cc at both the plus and minus ends.

Less polymer will form if the concentration of free actin monomers is lower than the Cc at both the plus and minus ends.

Actin polymerization encourages FAK and Src to activate small G proteins by signalling to GEFs and GTPases (e.g., Rho and Rac). The actomyosin network is then forced to develop as a result of G proteins' induction of cytoskeleton-regulating proteins.

What stops cells from forming actin polymers?

Actin monomer is sequestered by monomer-binding proteins, reducing its availability for polymerization. As a result, actin does not polymerize when monomer-binding proteins are present in stoichiometric levels.

Q. If a cell increases the activity of its actin severing proteins, will it lead in the short term to MORE or LESS actin polymer mass? Chose the most accurate answer.

Increased severing activity will result in LESS polymer under any conditions.

Increased severing activity will result in NO CHANGE in the total amount of polymer under any conditions. It simply results in a larger number of smaller filaments.

Increased severing activity will result in MORE polymer under any conditions.

If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then LESS polymer will result.

If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then LESS polymer will result.

The first species to live on new land, such as that formed from volcanic lava, are called ________.
JulsSmile [24]

The correct answer is D. Pioneer species

Explanation:

In biology, the term "pioneer species" refer to the first species that colonize new environments or environments in which there is no biodiversity for example lands that have been affected by fire, lava, etc. These species are in most cases plants or small organism that are resistant and able to adapt to the harsh conditions of new land. Additionally, this concept differs from keystone and foundation species because these two concepts describe species that have an important role in the ecosystem rather than those that first live on new land. Therefore, the first species to live on new land are the pioneer species.
