Tear glands have vesicles that release their secretion by exocytosis. These are classified as ___________ glands. However, _____
Vilka [71]

Answer:

1. Merocrine

2. Holocrine

Explanation:

Merocrine glands are the exocrine glands that synthesize their secretions on ribosomes attached to rough ER. These secretions are packaged by the Golgi complex into the secretory vesicles and are released from the cell via exocytosis. Tear glands, salivary glands are some examples of merocrine glands.

The cells of holocrine glands do not have vesicles but accumulate a secretory product in their cytosol. The mature secretory cells rupture to release the secretory product. This results in the presence of large amounts of lipids from the plasma membrane and intracellular membranes in secretions of these glands. One example of a holocrine gland is an oil-producing gland of the skin.

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.

Match the following terms and descriptions. 1. cloning most controversial method of genetic engineering 2. hybridization breedin
Savatey [412]

Correct matches of terms and its descriptions:

1. Cloning (most controversial method of genetic engineering)

2. hybridization ( breeding organisms because of beneficial traits)

3. recombinant ( DNA DNA from different biological sources that have been combined and culture)

4. selective breeding ( breeding two different species to make a new individual)

Selective breeding is also called artificial selection. Hybridization.is mating organisms of different species to create a hybrid.  Cloning produces similar copy of genetically identical individuals.
