Explanation:
This is the only one that is true.
I am a guy, but I know a lot about girls and how they work, the hormone is called endometrium. It prepares the female body for pregnancy and so on.
Answer:
Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.

Trypsinogen is split by the enzyme enterokinase to form an activated molecule of the protease trypsin. Which of the following would confirm that the activation of trypsin is an example of how a positive feedback mechanism can amplify a biological process?
A. The activated trypsin enzyme can use enterokinase as a substrate
B. The trypsin produced by the reaction is capable of splitting and activating additional trypsinogen molecules
C. If levels of trypsin were to get too high, the trypsin molecules would inhibit the enzyme enterokinase
D. Each mRNA molecule that codes for trypsinogen can be translated repeatedly to form many peptide molecules
<h3><u>
Answer:</u></h3>
Trypsinogen molecules are first split into the active enzyme Trypsin by enterokinase. Then the Trypsin being a protease itself, works on Trypsinogens and converts them to Trypsin. Thus this is a positive feedback.
Option B
<h3><u>
Explanation:</u></h3>
Trypsinogen is a proenzyme which is secreted by pancreas into the duodenum. Enterokinase is a intestinal enzyme that is secreted from the small intestinal glands. Enterokinase works on the Trypsinogens to convert them into trypsin by splitting a peptide chain from the proenzyme. This trypsin then digests a variety of proteins and peptides from diet.
Trypsin is a protease and the proenzyme Trypsinogen is a protein. So trypsin works on the secreted trypsinogens too and amplify the production of trypsin from the trypsinogens to enhance the digestion process. Thus, a positive feedback chain is seen here.
Answer:
Your answer is Molecular pharming.
Explanation:
Molecular pharming -It is defined as the production of active pharmaceutical substances in genetically modified organisms (GMOs). - Plants are preferred as plants do not carry pathogens. Hope this helped :)
