Answer:
Vitamin D is essential for strong bones,because it helps the body use calcium from the diet.
Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.
Answer: soil tests are most useful during the growing season to monitor plant nutrient uptake.
Explanation:
The nitrifying bacteria will convert ammonia to nirites in the nitrogen cycle. this will happen in first stage. correct me if im wrong
During cellular respiration, electrons are produced. The oxygen molecule accepts these electrons, then combines them with protons to make water. This outputs ATP, which is what the rabbit uses for energy. At the end of the process, carbon dioxide is released. From here, the carbon dioxide travels to one of the rabbit's favorite plants. This helps plants breathe. Sunlight penetrates the leaves of the plant, which are generating into sugar molecules within the chloroplast. The substance is known as chlorophyll. Electrons make the chemical process go more quickly. At the end, the plant releases oxygen back to the rabbit.
Can I get brainliest? I hope my answer suffices :D
