Answer:
The Six Kingdoms. When Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals. But the use of the microscope led to the discovery of new organisms and the identification of differences in cells. Today the system of classification includes six kingdoms.
Explanation:
This scientific study revealed that predation is the dominant factor affecting prey population on cycling. Population cycles is the feature where populations rise and fall over a predictable period of time. For example there are some species where population numbers have reasonably predictable patterns of change. From the study depicted in the question; when snowshoe hares are scarce, many lynx leave their home range in search of food. An increased predation of the hare due to high populations of lynx and other predators increases the decline in the hare population.
The f1 generation may have genes for short plants just that the genes for long plants are dominant over the genes for short plants(recessive) so when cross pollination happen and that two f1 long plants which are homozygous cross pollinate, the recessive genes have a chance of being paired up in new offspring(F2 offspring) thus the possiblity of short plants in f2 generation
