1 2 and maybe 3 for sure 1 and 2 not 3 though
Answer:
D
Explanation:
Intestinal cell takes in glucose against Concentration gradient (uses energy in the form of ATP) to transport glucose into cell.
In blood cell, uptake of glucose occurs down concentration gradient. Hence, its facilitated diffusion (passive transport)
Glucose is a polar molecules due to presence of polar hydrophilic - OH group, hence carrier proteins are needed to provide a hydrophilic channel for glucose to enter the cell via facilitated diffusion.

<span>simple and complex
"complete and incomplete" are terms used for proteins in nutrition. "macro and micro" are terms used for nutrients in nutrition. And " saturated and unsaturated are terms used for fats also in nutrition.
The difference between simple and complex carbohydrates is related to the way they are digested. Simple carbohydrates are quickly absorbed and ready to be used, while complex carbohydrates take longer to be absorbed and supply energy through a longer period of time.</span>
Answer;
A) respiration of living organisms.
D)absorption of CO2 from the atmosphere by ocean water.
Explanation;
-The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion.
-Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms - including all plants and animals - release energy from their food using respiration. Respiration and combustion - burning - both release carbon dioxide into the atmosphere.
