Multiple Choice

In order for cross-pollination to be successful

1

the pollen from one plant must be transferred to different plant's stigma

2

the pollen from the same plant must be transferred to the same plant's stigma

Multiple Choice

The jellyfish alternates between sexual and asexual reproduction.


An advantage of the jellyfish reproducing sexually is that sexual reproduction

1

produces identical offspring

2

allows for less crossing over of genetic material

3

requires less energy to complete

4

provides genetic variation in the offspring

26

Multiple Choice

In the 1800's, the average sheep in Britain produced far more wool than did the average sheep at the beginning of the 1800s. This was most likely due to farmers choosing only the wooliest sheep as breeding stock.

artificial selection

2

natural selection

3

evolution

4

cloning
