Most animal cell membranes have proteins that pump ______ ions out of the cell and potassium ions into the cell.A) calcium
B) carbon
C) magnesium
D) sodium

Answers

Answer 1
Answer: The answer is D) sodium.

Most cell membranes have a sodium-potassium pump. It is an enzyme that pumps sodium ions out of the cell and potassium ions into the cell. It moves 3 sodium ions out and 2 potassium ions in. Both ions are transported against the concentration gradient. Thus, the sodium-potassium pump provides one positive charge carrier to the extracellular space.

Photosynthesis continues to increase with temperature. true true within limits not true

Answers

The answer is true within limits.

Photosynthesis occurs in the leaves of green plants. During photosynthesis, carbon dioxide and water are converted into using the energy of sunlight glucose and oxygen. Thus, the limiting factors for photosynthesis are carbon dioxide, light intensity, and temperature.
Temperature affects an activity of some enzymes characteristic for light independent reactions. It actually doubles the enzyme rate for every 10°C. So, if temperature increases, the rate of these enzymes will increase, as well as the photosynthesis rate. But, this is limited. After reaching optimum temperature, the photosynthesis rate will decrease because the enzymes will denature.

Answer:

true within limits

Which is the result of telophase 1 and cytokinesis

Answers

Answer:

The result of Telophase 1 and Cytokinesis is two haploid daughter cells that are genetically different from the original cell.

Explanation:

Telophase I. At each pole, during this stage, there is a complete haploid set of chromosomes (but each chromosome still has two sister chromatids). A cleavage furrow appears, and by the end of this stage the parent cell has divided into two daughter cells. This separation of the cytoplasm is called cytokinesis.
