What is the “Distal Convoluted Tubule”?
Answer:
C
Explanation:
Whenever we lift weights, we are exerting force against the barbell. In physics, we measure force using Newton's Second Law of Motion via the equation f = ma, or put differently, force is equal to mass multiplied by acceleration. To generate more force, we must either increase mass or acceleration (or both).
Answer:
apply oxygen via nonrebreathing mask, start an IV with normal saline, and administer 1 mg of epinephrine 1:10,000 via IV push
The main components are the blood cells such as white blood cells, red blood cells, and platelets. The other components represent additional information about these cells including their size, color, function, and maturity.
Answer:
The answer to fill in the blank in this question: Some hormones act through cell membrane receptors that stimulate adenylate cyclase activity and production of:____, would be: cAMP.
Explanation:
In the process of hormonal regulation of cells there are two ways in which this can happen: direct activation of DNA inside a cell through steroid hormones, who do not need any kind of mediators to enter the cytoplasm of a cell and activate its genetic material, or indirect activation, which is the common way for non-steroidal hormones, such as epinephrine. In this second scenario a hormone will reach the cell and lock onto a receptor on the plasma membrane. The effect is that a G-protein, which is adjacent to the receptor, activates the second-messenger system, meaning that the activity the hormone came to initiate, will depend on these mediators. the G-protein will then activate adenylate cyclase, which in turn will activate ATP and transform it into cAMP. It is cyclic AMP (cAMP) which will finally relay the original message sent through the hormone, to the genetic material of the cell.
