Answer:
B
Explanation:
We never see short bristle males, suggesting some type of lethality. I.e. any males who inherit the mutation die before birth so we don't see the phenotype. This also hints that it could be X-linked.
Females can be short bristled, but males can't, as it is likely lethal. This suggests that having one copy of the short bristle trait without the long bristle trait is lethal (as males as XY and so only have one copy of the trait). The female then must be heterozygous for the short bristle trait (which also explains how in generation F2, long bristle males can be produced, as if she was homozygous males would all be short bristled, and therefore dead, so there would be no males.
Since the first short bristle female is heterozygous, the trait for short bristles must be dominant.
However, since evidence suggests the trait is X-linked, it cannot be autosomal, as suggested in B.
Antagonist, which is a drug that inhibits the production of a chemical in the body. This is the opposite of an agonist drug.
A. Snails and crayfish would not survive in Birch Lake at a pH of 6.2.
B. Once they die out, the walleye will disappear as well.
Answer:
Connective
Explanation:
Connective tissues are repeated arrangement of structure that binds and supports body parts and fit them into their organ shape. It component includes the cell and extracellular matrix (protein fibres and proteoglygans). They provides support and framework for the body, maintaining body forms and also mediate the exchange of nutrients between their circulation and other tissues.
A decomposition reaction occurs when ionic or covalent bonds are broken and elements and or ions or simpler molecules are formed.
