Cells must use energy to move a substance against a concentration gradient i.e., from a compartment with a low concentration of

garik1379 [7]

Answer:

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

Explanation:

In general the concentration of sodium ion is higher outside the cell in the extracellular fluid and the concentration of potassium ion is higher inside the cell.

During an active transport, a cell uses energy to move molecules against the gradient as a part of primary active transport. In the secondary active transport, the molecules move as per the electrochemical gradient established by the primary active transport.

In primary active transport, sodium ion moves out of the cell and potassium ion moves into the cell through the assistance of sodium potassium pump. In order to maintain the stability, calcium ion from the sarcoplasmic reticulum is pumped out of the cell

Hence , the correct answers are

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

C) Binary fission and multiple fission <br> differentiate

padilas [110]

Answer:

Binary fission

1. Forms two daughter individuals

2. Divides only once

3. No residue is left

4. Takes place in favourable conditions

5. Immortality is present

Example: Amoeba reproduces by binary fission

Multiple fission

1. Forms many daughter individuals

2. Divides repeatedly

3. Residue is left

4. Takes place in favourable as well as unfavourable conditions

5. Immortality is absent

Example: Plasmodium reproduces through multiple fission
