Answer: it would be b. a biologist studying insects.
Answer:
When blood glucose level rises beyond the threshold levels, the pancreas secrets hormones insulin. The latter ensures entry of glucose into the cells through Glut transporters for cellular utilization, therefore reducing the blood levels., and promotes storage as glycogen in the liver and muscles.
How ever if the glucose levels drops below the set point, an hormone glucagon is also produce by the pancreas to cause the liver o withdrawal and breakdown glucose storage as glycogen back to glucose thus raising the blood glucose level back to the normal levels.
This is an example of negative feedback mechanism, because the increase in the input levels (blood glucose levels) brings about a counter mechanisms (insulin secretions)as output , to reduce the elevated levels by promoting entry into the cells,, thus bringing the levels to threshold levels.
Thus insulin is acting in a negative feedback mechanism to control blood glucose levels
Explanation:
Answer:
a parallel universe or multiverse?
Explanation:
There is a concept that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. The concept is known as a "parallel universe," and is a facet of the astronomical theory of the multiverse
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,
Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,
Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,
If V = 2V and p = 2P
Then,
Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
Answer:the cell membrane provides protection for a cell
Explanation: that some molecules can diffuse across the lipid bilayer but others no
