Kingdom family phylum class order? I learned this last year but I don’t remember fully
Answer:
The pituitary gland produces FSH which causes the development of a follicle in the ovary. As the egg develops inside the follicle, the follicle produces the hormone oestrogen. The oestrogen causes growth and repair of the lining of the uterus wall. Oestrogen inhibits FSH.

Answer: All of them seem to apply.
Explanation:
A., Its important to know if your car that is being collided is a small car or big truck, as they will end up effecting who gets hurt the most.
B., Same thing as A. but with the other vehicle.
C., The velocity matters a lot with a collision, since a slow crash won't have as much damage as a car going fast and hitting someone. Also it won't be as likely to be fatal if the car crashing into you is going slow.
D., This is the only one I'm not too sure on, but it seems like how fast the car can accelerate once collided with would be a big factor on whether it would come to a halt or skid across the road.
Answer:
the correct sequence of the events happened during nerve impulse is (d): 2,1,4,3
Explanation:
Originally K+ ions remains inward the membranes while Na+ ions remains outward to maintain a resting potential of membrane.
Upon stimuli Sodium channels open on membrane and Na+ diffuses inward leading to the depolarization of membrane that is it becoming more positive due to Na+ and K+ ions.
To regain it polarized state or in repolarization state Potassium channels open and K+ begun to diffuse outward while Sodium channels gets closed and Na+ ions remains inside the membrane.
Potassium channels are not efficient as compared to Sodium Channels, so an excess amount of K+ion move outward so Hyperpolarization state achieved.
As the both ions are on the wrong side and will not be available for the next nerve impulse. Hence in Refractory period by the help of Na+/K+ pum, both ions move back to their original place and membrane achieve its resting membrane potential state.
Answer:
Water's ionization property creates positive and negative ions, which are essential for chemical reactions.
