Introduction:
For the regulation of other organs in the body, the endocrine system in response to internal signals secretes various hormones. The hormones are chemical signals secreted by the endocrine glands.

Answer to Problem 1DYKB
Correct answer:
Programmed cell death/destruction of aging cells is not a general process controlled by the endocrine system. Therefore, option d. is correct.
Explanation of Solution
Reason for the correct statement:
Option d. is given as “Programmed cell death/destruction of aged cells”. The endocrine system controls and regulates the growth, development, and
Hence, option d. is correct.
Reasons for incorrect statements:
Option a. is given as “development, growth, and metabolism”
Endocrine system stimulates the secretion of thyroid hormones that are responsible for growth, development of some tissues and organs and also involved in the metabolism of the body. Hence, option a. is incorrect.
Option b. is given as “control of reproductive activities”. Endocrine glands control reproduction by stimulating the secretion of testosterone, progesterone, and estrogen that controls the growth and development of male and female reproductive parts.
Hence, option b. is incorrect.
Option c. is given as “maintenance of homeostasis of blood composition”.
Endocrine controls the homeostasis of blood composition by stimulating parathyroid hormones, insulin, glycogen. Hence, option c. is incorrect.
Hence, options a., b., and c. are incorrect.
Endocrine glands are made up of epithelial tissues, which cause the release and production of hormones.

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA?

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
