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 astronomical unit, otherwise known as AU is used to measure long distances in the universe.
In photosynthesis oxygen is released to the atmosphere which means the third option is correct.
