Answer: Mitosis creates an exact replica of the parent cell, while meiosis shows genetic diversity.
Explanation:
I did the test too
The answer is; C
This phenomenon is called bottleneck effect and drastically affects small populations in comparison to large ones. The mudslide wipes off most of the population B at the base of the hill base. Due to their small population, a large proportion of the population is lost and the pollution loses most of its alleles leaving a small proportion to continue the population succession. Its diversity is hence reduced as it repopulates. The larger population is not greatly affected because it covers much of the hillside.
Humans can have very damaging effects on ecosystems. An example is if we cut down trees, not only does that disturb the vegetation and plant life, but it also disturbs the life of the animals who relied on those trees for food and shelter.
Options are:
A. a fish
B. an aquatic bird
C. a mosquito
D. a dragonfly
Answer: Fishes
Explanation:
A metapopulation can be defined as a small population that cannot itself make a large population that is stable.Many sub populations are connected intermittently to combine and form a population.
Small population of fishes would have been separated for most of the years and are joined by when floods occur and these populations are connected by kettle ponds.
Rest of the three organism like bird, mosquito and dragon fly cannot be separated so as to form a metapopulation.
