Answer:
A. Conduct impulses faster.
Explanation:
Myelinated axons are called that way due to the myelin sheath that surrounds them. Myelin has an insulation property so electrical impulses cannot travel through it, except on certain sites called Nodes of Ranvier. In order for electrical impulses to be conducted on myelinated axons they must "jump" from one Node of Ranvier to the next, and thus conduction is faster. This is called saltatory conduction.
Answer:
Interactions between biotic and abiotic components regulate carbon dioxide and water levels.
Explanation:
Abiotic factors include temperature, water, humidity, etc; while biotic factors include all the forms of life. These factors interact in the ecosystem to maintain its homeostasis. For example, during the photosynthesis, plants use the energy of the sun water and carbon dioxide to produce food (carbohydrates) and this process converts carbon dioxide (CO2) to oxygen, which is critical for maintaining the homeostasis of the ecosystem.
I think True, sorry if i'm incorrect :(
Answer:
A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.
It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.
