Answer:
option C. permissive stimuli
Explanation:
The three major kinds of stimulus that triggers the endocrine glands to synthesize and release hormones are humoral stimuli, hormonal stimuli and neural stimuli. The humoral stimulus regulates the release of hormones with the changes in the concentration of extracellular fluids. For example, the increase of glucose concentration in blood causes pancreas to release hormone insulin.
The hormonal stimuli allows secretion of hormone only with the secretion of any other hormone. The hypothalamus gland secretions allows the anterior pituitary gland to secrete hormones. The release of thyroid hormone is an example of hormonal stimuli.
The neural stimuli allows the production of hormones directly from the glands. The production of epinephrine and norepinephrine hormones are the example of neural stimuli. Thus, option C is correct.
Answer:
The correct answer is option a. young adult.
Explanation:
Epstein-carr virus infects in the patient or people with weak immune system groups. Epstein-carr virus causes a different type of disease and also said to cause cancer. These viruses are common in childhood or early adults or weakened the immune system by the disease like HIV/aids. In young adults, symptoms are not visible by these viruses.
Thus, the correct answer is option A. young adult.
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.
