Answer:
B
Explanation:
B is the most likely consequence because of the following facts we are told:
- After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees
- Adult apple maggots will only mate on the type of tree on which they were born.
This provides a geographical isolation (because they are feeding and laying eggs on separate trees) and reproductive isolation (because they will only mate on the type of tree on which they are born).
These two factors increase the chances that apple maggots feeding on apple trees will only encounter those who have mated on the same tree, and continue to mate this way. Over time, the populations (i.e. apple tree vs hawthorn tree) will intermix less and less. This will mean the genetic pool will become distinct, and natural selection will be acting differently (different habitats and different genes), encouraging speciation.
The thick loess deposits in South Dakota, Nebraska, and Iowa come from the glacial sediments from the last ice age glacial period.
Answer:
c. Cellular respiration is affected by the availability of reactants.
Explanation:
No doubt the cell has less availability of oxygen (reactant). When the oxygen cannot be efficiently pumped to cells for proper cellular respiration to occur the respiration shifts to anaerobic that produces lactic acid as waste and soreness occurs. If cell has a sufficient amount of oxygen the cellular is no more effected.
The thalamus
Located in the central part of the brain, the thalamus processes and coordinates sensory messages, such as touch, received from the body.
