Answer: A- Disruptive selection
Explanation: Disruptive selection increases genetic variation as the population begins to be more different when selection existing in nature chooses multiple phenotypes reaching the highest degree which each have particular benefits. However, they tend to make single-celled life form that has interposed characteristics to produce smaller offspring while allowing the organisms that have the highest degree of characteristics to produce more offspring.
Answer:
The correct answer is FtsZ is very similar to the tubulin subunit that form microtubules in eukaryotes.
Explanation:
FtsZ protein plays a significant role during bacterial cell division.FtsZ is a GTP binding protein and also contain GTPase enzyme that helps in the hydrolysis of ATP .
The principle function of FtsZ protein is to form filament in which the subunits are arranged in a specific manner.The filament then form a ring like structure which is called Z ring.
The movement of subunits of FtsZ generate force that helps the cell to divide.
It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.
Answer: Estuaries
Explanation:
Estuaries are areas where freshwater streams or rivers merge with the ocean. This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem. Microflora like algae, and macroflora, such as seaweeds, marsh grasses, and mangrove trees (only in the tropics), can be found here.
