Aleks [24]

Answer:

Edema occurs when blood pressure exceeds the counteracting force of the vascullar walls in the bloodstream, so fluid remains in the spaces surrounding cells and body tissue swells.

Explanation:

The intravascular hydrostatic pressure increases due to an increase in fluids, therefore the vessel walls begin to perceive this increase in pressure in their walls, generating fluid extravasion to areas of lower pressure.

Most of the food and oxygen in the environment is produced by the action of

Stolb23 [73]

The correct answer is (4) Autotrophic organism.

Green plants make their own food by the process of photosynthesis using sunlight. Most of the autotrophs use carbon dioxide, sunlight and carbon dioxide to produce glucose that is used by the plants to obtain energy. Most of the oxygen comes from these organisms and decrease in the number of green plants can lead to several problems due to decrease in the amount of oxygen. Example: green plants, algae, and even some bacteria. This food and oxygen is produced by the action of autotrophic organisms

How can some spores survive adverse conditions

ser-zykov [4K]

Answer:

In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa.

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.
