The two types of currents are direct current, which is abbreviated DC. And alternating current, which is abbreviated AC.
Answer;
-In the smooth ER
In certain kinds of muscle cells, calcium ions are stored in the smooth ER.
Explanation;
-The smooth endoplasmic reticulum is the part of the endoplasmic reticulum (ER) which does not have ribosomes bound to it, thus not exhibiting the bumpy appearance shown by the rough endoplasmic reticulum.
-The smooth ER is important in the synthesis of lipids, such as cholesterol and phospholipids, which form all the membranes of the organism. In addition it is important for the synthesis and secretion of steroid hormones from cholesterol and other lipid precursors.
The answer is a. True.
The photosynthesis occurs in leaves, which absorb sunlight. But the amount of absorbed sunlight by leaves depends on both the leaf surface area and intensity of life. So, t<span>he leaf surface area is just as important as the intensity of light in photosynthesis. But, if we take into consideration other leaves' functions, such as gas exchange, then the intensity of light has no effect on it. Thus, in that case, the leaf surface area is more </span><span>important than the intensity of light.</span>
The best option would be the letter A. They supply freshwater to support life on Earth.
Freshwater is the ultimate source of water in the terrestrial biome. It is not only important in the terrestrial biome but also in the aquatic ecosystem as it helps in transporting nutrients (ex. river is connected to the ocean).
Orgainsm. This is the only word that makes sense. The statement is already talking about interrelated systems, so system wouldn't be the answer.
Tissue and Organ do not define a functional plant or animal either.
I hope this helps!
