Answer:
B: They have half the normal amount of genes
Explanation:
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.
One of the most intelligent invertebrate animal is the octopus. These animals belong to the cephalopod class of molluscs. These animals demonstrate relatively complex reasoning especially when capturing prey. They also demonstrate their intelligence by their communicating skills and some even show signs of learning.
The cells have nuclei that vary in size and shape, termed pleomorphism.
Pleomorphism is usually defined in biology as the occurrence of multiple structural forms during the life cycle of an organism. In anaplasia, it represents multiple structural forms of nuclei. Pleomorphism is a characteristic feature found in malignant neoplasms, and dysplasia, but it can also be found in certain benign cell types.
