The pituitary gland secretes follicle stimulating hormone, which acts on the follicles and stimulates them to produce progesterone.
Answer:
to divide food cans from soft-drink cans
Explanation:
An electromagnet is based on the principle that current through a coil produces magnetic field. Magnetic objects such as Iron, nickel, cobalt or objects made from their combination are attracted by the magnet. This property is used to separate materials in recycling plant.
Steel (alloy of iron) would be attracted by the magnet where as aluminium would not be. Thus, steel food cans can be separated from the aluminium soft-drink cans using an electromagnet.
Answer:
i cant read that maybe type it out?
Explanation:
Nitrogen and Carbon make up amino acids, that create proteins.
Phosphates make up DNA and ATP energy which allows for the transport of proteins and lipids in and out of a cell.
Answer:
The correct answer is E. none of the above. The population will drops below 100 when t ≥ 38.
Explanation:
Given A= A0 e^kt. The population 10 years ago is A0, the population today is A(10), and we have to find the value of "k" and then the time when population drops below 100.
So, A(t) = 1700 e^kt ⇒ A(10) = 1700 e^k(10) ⇒ 800 = 1700 e^k(10) ⇒
800/1700 = e^k(10) ⇒ln (800/1700) = k(10) ln e ⇒ -0.754/10 = k ⇒
k = -0.0754.
Now you have all the parameters, so you can find the time at which the population drops below 100.
A(t) = 1700 e^kt ⇒ 100 = 1700 e^(-0.0754)t ⇒100/1700 = e^(-0.0754)t ⇒
ln(100/1700) = (-0.0754)t ln e ⇒ [ln(100/1700)]/(-0.0754) = t ⇒
t = 38.
So, the population will drops below 100 when t ≥ 38.
