Smooth muscles depolarize as a result of a transmembrane current of Calcium ions. When an action potential depolarizes the muscle cell membrane, it also travels into the body of the cell via the t-tubules. Unlike skeletal muscle, smooth muscle is dependent in two sources of calcium in order to intiate contraction. These two sources are calcium sequestered in the S.R. of the smooth muscle cell.
The answer would be C. because velocity describes the speed of an object in any given direction
Answer:
The answer is c, your welcome;)
Explanation:
Biotic:
Animals: animals are consider biotic because they are living things, they breath, walk, eat, sleep, reproduce, and drink water. and since biotic means living things, the animals are under the biotic category.
Plants: same as animals, but with plants they reproduce asexually meaning it requires only one organism to produce another life. Anything with cells in them are consider a living thing.
bacteria: same as plants and animals, they have cells so they are consider a living thing.
There are other types of biotic factors out there like producers, consumers and decomposes. Here are the ten things of biotic:
1. Bamboo plants (producers)
2. Banana Trees (producers)
3. orchids (producers)
4. Seaweeds (producers)
5. anteater (consumers)
6. Bears (consumers)
7.zooplankton (consumers)
8.bacteria (decomposers)
9. earthworms (decomposers)
10. termites (decomposers)
Those are the ten examples of biotic.
Abiotic:
Some of the examples include temperature, sunlight, soil, gases and atmospheric, these are consider the non-living things but here are 5 examples of abiotic factors in the ecosystem.
1. Altitude
2.pollution
3.soil
4.wind
5. Ph
Hope this helped :)
Have a great day
