A garden has a higher level of oxygen compared to a city road. A garden has plants and trees. Plants produce oxygen and sugars from carbon dioxide. A city road is composed of industrial buildings, vehicles, humans, and animals. They consume oxygen that is why the oxygen content is lesser on a city road.

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.

The stimulation of an inadequate number of sodium channels for the generation of a positive sodium channel feedback loop is cons
diamong [38]

Answer:

Sub-threshold

Explanation:

If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.

The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.
