Id say they stay with them and nurture them
Answer:
The SRP would remain bound to the SRP receptor on the ER surface.
Explanation:
Because Signal recognition particle (SRP) receptorl, is a dimer composed of 2 different subunits that are associated only with the rough ER in human cells. It functions mainly is to identify the SRP units. And it SRP binds to a hydrophobic N-terminal signal sequence as it emerges from the ribosome.
The olfactory epithelium is a specialized epithelial tissue inside the nasal cavity that is involved in smell. In humans, it lies on the roof of the nasal cavity about 7 cm above and behind the nostrils.
Answer:
The correct answer is option a, that is, it is a kind of natural selection.
Explanation:
A procedure of speciation in which the phenomenon of natural selection enhances the reproductive isolation amongst the population of two species is known as reinforcement. This takes place as a consequence of selection functioning against the generation of hybrid entities of low fitness.
The concept was developed originally by Alfred Wallace, also considered as the Wallace effect. Reinforcement signifies towards some of the circumstances in which selection can encourage an enhancement in prezygotic isolation, affecting the procedure of speciation straightforwardly.
Only small, uncharged molecules (like 02 for example) can go in or out of the cell by simple diffusion.
Since glucose is a relatively large molecule and ions (like Na+, Cl-) have an electric charge, they are unable to diffuse into or out of the cell.
However, since ions, glucose and other big or charged molecules are necessary for the functioning of the cell, there are special means of transport for them.
Integrated into the cell wall there are membrane proteins which serve as canals for transporting specific molecules like ions, glucose, etc.
