Answer:
I-3, II-2, III-2 are all definitely carriers
It is possible find the genotype of individual II-1 because the he inherited his father's y which does not carry the trait (because only x chromosomes have the trait) and his mother's x chromosome, but the mother is not a carrier.
In science, a theory is a hypothesis, and a law is a statement of a observed phenomenon proven to be true.
- A theory explains why a natural phenomenon occurs.
- Scientific laws summarize a set of observations about a natural phenomenon that was witnessed.
- Both can be revised, used to make predictions, and are based off of a hypothesis.
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.
