Answer:
C. Producers
Explanation:
Producers (plants) can turn the sun's energy into usable energy by photosynthesis. They are at the bottom of the food chain; all of our energy comes from them. :)
As a result of the non-selectivity of kidney's filtration of small molecules, useful substances must be selectively reabsorbed to the blood. Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered. Glomerulus lets fluid and waste products pass through it, however, it prevents blood cells and large molecules, mostly proteins, from passing.
The answer is (D), because none of the other answers make sense
There are many reasons are specific to the plant and our needs but remember this, without us modifying plants we would have been extinct thousands of years ago, everything you eat today does not exist in nature and if it does exist is either inedible, toxic, or too small to provide important nutrition.
<h3>What is grafting?</h3>
When the tissues of plants are joined together to let them continue their growth together as one, then such a practice is known as grafting.
Grafting is commonly practised in horticulture and agriculture for the growth of commercially important plants in an asexual manner.
In the process of grafting, the upper part of the combined plant is known as the scion and the lower part is known as the stock.
Thus, this could be the answer.
