Answer: The release of inactive form of enzyme is important because when the enzyme will active on its release it can digest the organs and glands from where it had been released to support the function of the enzyme only when it is required to be released and promote its functioning at the target site the enzyme is required to be released only in an inactive state.
Explanation:
Pepsin is a an enzyme secreted by the stomach cells in the inactive form that is called as pepsinogen. The function of the pepsinogen is to digest protein in the food. The activation of pepsin requires an acidic pH maintained by the hydrochloric acid in the gastric secretion of stomach. The pancreatic cells secrete enzyme trypsinogen which is activated into trypsin when it enters into the duodenum of the small intestine by the enzyme enteropeptidase.

Answer:
22 mu
Explanation:
Since maximum number of flies are observed with +pb and s++ phenotype, they are the parental combinations.
Minimum number of flies are observed with +p+ and s+b phenotype hence they are the result of double crossover.
Gene order would be +bp and s++ since it is the only case which would lead to production of above mentioned double crossover. Hence gene b is in the middle of genes s and p.
Single cross over between genes s and b will give progeny +++ and sbp.
Map distance between s and b loci = recombination frequency =
(number of recombinants/ total progeny)*100
= [(single cross over between s and b + double crossover)/total progeny]*100
= [(102+106+7+5/1000]*100
=(220/1000)*100
=0.22*100
=22 mu
An adrenal gland can develop an uncommon, often benign (noncancerous) tumor called a pheochromocytoma.
- A (pseudo)hypoxic signature is seen in many solid tumors, such as paraganglioma (PGL) and pheochromocytoma (PHEO). It has been demonstrated that (pseudo)hypoxia encourages the development of tumors and therapeutic resistance.
- Hypoxia-inducible factors (HIFs) are the main mediators of the transcriptional hypoxic response.
- The transcription of hypoxia-responsive genes, which are involved in cancer, is induced by high levels of HIFs. Catecholamine-producing tumors called PHEOs and PGLs develop from sympathetically or parasympathetically generated chromaffin tissue.
- HIF signaling appears to be crucial for the growth and development of PHEOs and PGLs, which may point to novel therapeutic strategies for the management of these malignancies.
