Answer:
Actin depolymerizing factor binds F-actin cooperatively and induces a conformational change in F-actin that causes it to twist further and become more destabilized. This twisting causes severing of the bond between actin monomers, depolymerizing the filament.
Explanation:
Actin filament depolymerization ensures the turnover of actin filaments within these structures and maintains a pool of actin monomers that permits the continual restructuring and growth of the actin cytoskeleton. ADF/cofilin influences actin filament turnover.
<span>The presence of rigid cell wall that gives the block like structure to the plant cells which is not the case with the animal cells which has soft membranes. Another reason for this kind of maintenance of plant cell shape is that the network of fibers that are present in the cytoplasm called as Cytoskeleton.</span>
Answer:
Plants and trees are the primary sources of food for a food chain or a food web. If the population of the primary producers reduces than it affects the whole food web. If the deciduous trees are destroyed due to a fire, there will be less food available for the primary predators. As a result, competition will begin between them and their population will decline. Due to this, the population of other organisms which fed on the primary consumers will also decline.
