Answer:
Secondary active transport by a symporter
Explanation:
Secondary active transport includes uphill transport of one substance against its concentration gradient coupled with downhill transport of another substrate. Glucose is transported against the concentration gradient into the cytoplasm and this active transport is driven by downhill transport of Na+ into the cells. This makes the transport of glucose a secondary active transport. Both glucose and Na+ are transported into the cell (in the same direction). Since both are moved simultaneously in the same direction, it is a symport.
Pollution would kill fish and other sea creatures. There would be no fish to catch and eat.
Plant cells
<span>There are several starting ingredients that are required for starting the process of photosynthesis. The most important are sunlight, water, carbon dioxide and certain minerals. Sunlight helps in building up the optimum temperature that is required to start the process of photosynthesis. Water is an important raw material that helps to absorb the carbon dioxide from the air. It also directly influences the opening and closing of the stomata. Carbon dioxide on the other hand is one of the most important raw material that helps to make glucose via the process of photosynthesis.</span>
