5 0

Answer:

The correct answer is - prokaryotic and unicellular.

Explanation:

Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.

These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.

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.

What type of rock does direct pressure make
natka813 [3]
I think it is called the METAMORPHIC ROCK.

It formed not only when the pressure changes but also with the heat. 

Good luck :)

Which describes oxygen content as Earth evolved over time? Oxygen levels sharply declined about 400 million years ago. Oxygen le
denis-greek [22]

Answer:

Oxygen levels stay above 15 percent starting 200 million years ago

Explanation:

Atmospheric oxygen levels are related to the evolution on Earth and changes in geochemical cycles that involve climate variations.

The presence of O 2 and evolution of oxygen gave new opportunities to the life on Earth. Oxygen levels in atmosphere have fluctuated between 15% and 35% of atmospheric volume, since the start of the Cambrian period.

So, form the starting 200 million years ago, oxygen level stay above 15 percent and the correct option is "B".
