Answer:
D Anaerobic respiration
Explanation:
The product of anaerobic respiration is the formation of either lactic acid (lactate) or ethyl alcohol as a waste product.
- Anaerobic respiration is a process that occurs in the absence of oxygen gas.
- When oxygen is lacking in cells, glcolytic process follows the anaerobic path way.
- This process produces very little energy for the body.
- During a period of intense exercise, anaerobic respiration usually occurs.
Answer:
b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake.
Explanation:
Plant cells have a rigid cell wall made of cellulose. Animal cells lack a cell wall.
When the plant cells are placed in a hypotonic solution, water enters into the cells and the cells expand. However, after a certain limit, the cell wall exerts wall pressure on the contents of the cell and does not allow it to take more water in. The wall pressure from the cell wall of plant cells protects them against bursting when placed in a hypotonic solution.
Animal cells burst out due to intake of water by osmosis when placed in a hypotonic solution. They do not have a cell wall to protect them from bursting.
That structure is called your DNA containing the chemical bases adenine, guanine, cytosine, and thymine.
Answer:
300% - 400%
Explanation:
The cardiac reserve is in the range of 300 to 400 percent (300% - 400%
) in normal young adults, while this percentage can be increased to 600% in trained athletes
