Answer:
Explained
Explanation:
No, Homeostatic regulation requires Three components namely, a receptor, a control center and an effector. Without a receptor, there cannot be homeostatic regulation. Even though it seems that heart rate varies and returns to some number, this is not technically homeostatic regulation. Blood pressure is homeostatically regulated - it has baroreceptors that monitor pressure, the brainstem that receives the information and nerves that then activate blood vessels to constrict or dilate to correct pressure (as well as other effectors) - but heart rate is not. Heart rate is not monitored by any neuron. Absolute water content of the body is not homeostatically regulated either - no neuron detects the number of water molecules, although neurons do detect the relative saltiness of the body.
First, scientists isolate the gene that controls insulin production. Then, they take that gene and insert into a plasmid (a circular ring of DNA found in bacteria). When the bacterium with that plasmid reproduces, it carries that insulin-producing gene. Then they can either mass-reproduce that bacteria or transfer the plasmid to another rapidly-reproducing bacteria. After some time, they harvest the insulin from the bacteria.
While it is a common belief to people in the ancient civilisations that the Earth is considered as "flat", the contrary idea that the Earth could be considered as "spherical" was first theorised by the famous ancient philosopher Aristotle when he observed that a circular shadow was cast by the moon during a lunar eclipse.
It’s C. If you search on google there is a whole quizlet that may answer some of your others questions too :)
