PLS help!!!!!! brainliest!!!! which activity produces an action potential in nerve cells?
A. mitosis
B. hormone secreation
C. release of neurotransmitters
D. exchange of ions
Answer:
Exchange of ions.
Explanation:
Release of neurotransmitters activity produces an action potential in nerve cells.
A depolarisation current causes an outburst of electrical activity, which is known as the electromotive force.
This indicates that the resting prospective moves toward 0 mV as a result of some activity (a stimulus).
A cell fires a nerve impulse when the depolarization reaches around -55 mV.

It affect the habitat of all living organisms, so that the ecosystem would become functionless in absence of keystone species.
On of the best example is prey-predator relationship.
Some important environmental influence of keystone species are, it affect organism's physical appearance.
There is an impact of parasites, diseases on prey and host population, act as a mutualist, absence of key stone species leads to domino effect.
For example in absence of carnivore, number of herbivores increased, hence the environment cannot support the infinite number of herbivore population.

what is cell cycle? in detail
Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

B. toward your lab partner.
C. toward another classmate.
D. away from all people.
Answer:
D
Explanation:
keep test tube away from all people
Always point the open end of the tube away from all people because the chemical is dangerous for human health and skin.
If we heat a substance or chemical in a test tube, we should hold it away from people because may be it can explode and the chemical split on the body that cause serious problems in people. We have to handle laboratory procedures very carefully because the chemicals are not good for health and can cause serious diseases in humans and can damaged the skin very badly so we can conclude that the open end of the test tube should be placed away from the people.

Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.

Which phrase best describes Earth's biodiversity?
a. greater in consistently warm areas
b. greater toward Earth's poles
c. greater according to energy needs
d. greater where temperatures are most variable
Answer:
A) greater in consistently warm areas
Explanation:
This best describes Earth's biodiversity because it is not greater toward Earth's poles, according to energy needs, or where temperatures are most variable. Consistently warm areas are where Earth's biodiversity tends to be greater.
In response to injury, cell fragments called platelets get activated to induce clotting. Activated platelets release factors that can in turn bind to specific membrane receptors on nearby cells. What type of signaling would this be considered
Answer:
Activated platelets express negative phospholipids on the exterior leaflet of their cell membrane, release vasoactive compounds, release cytokines, and release growth factors.
When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin.
Platelets contribute their hemostatic capacity via adhesion, activation and aggregation, which are triggered upon tissue injury.
