Due to global warming, some tree species bud and develop fruits earlier in the spring than before. In response, some bird popula

tions that migrate to reach this food source start their spring migrations earlier in the year. How might a gradual climate change cause a population of birds to stop migrating altogether?

It may make birds confused as to when the food source will be there, so they stop visiting because the food source isn't there when they thought it was going to be. So I think they would stop migrating because of confusion mainly.

Renal failure occurs when the Kidney's fail to function ar required.

<h3>What is renal failure?</h3>
  • When your kidneys are suddenly unable to filter waste from your blood, you experience acute renal failure.
  • Dangerous levels of wastes may build up when your kidneys lose their filtering capacity, and your blood's chemical composition may become out of balance.
  • Acute kidney failure, which is often referred to as acute renal failure or acute kidney damage, occurs suddenly, typically within a few days.
  • The majority of cases of acute renal failure occur in patients who are already hospitalized, particularly in severely ill patients who require intensive care. Acute renal failure is serious and needs aggressive care. Acute renal failure, however, might be curable.

What happens as a result of ion flow at a presynaptic terminal?
Anarel [89]

The correct answer is: Release of neurotrasmitters from the synaptic vesicles  

Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine), Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells.

Determine whether the following events occur during initiation, elongation, or termination. This is regarding protein synthesis.
erik [133]

Answer:

The provided events can be classified as:

Initiation

  • In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
  • In E. coli, mRNA binds to the 30S ribosomal subunit.

Elongation

  • In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
  • Initiator tRNA enters the P site.
  • In E. coli, EF-Tu hydrolyzes.
  • Translocation occurs

Termination

  • The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site

Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).

It is divided into three stages:

Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.

Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next  codon.

Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.
