The population of the ground squirrels will be limited by the population of the hawks. The population of the hawks, thus, will be a limiting factor for the population of the ground squirrels. The Hawks are the birds of prey that feeds on squirrels. With the increased number of hawks in the same area as them will put these squirrels in danger. The population of the tree squirrels, however, will have no affect on the population of the ground squirrels. The genetic variability and breeding season are not limiting factors for their population either.
Hence, the correct answer is 'option B - a population of hawks'.
Answer:
tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.
Explanation:
The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.
According to scientists, most widely used modern systematic practice
depends upon the assumption that a change from character in one species
to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.
In this scheme, there are no independently derived parallel evolutionary changes,
nor convergences from a variety of states to a single one. Therefore, when two organisms share a
character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.
Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.
The higher-density liquid water shelters organisms from cold air better than the less-dense ice.
Geographical Isolation is the mechanism that might have led to the appearance of the Hawaiian honeycreeper.
Geographical Isolation is the term used that refers to a population of animals, plants, or other organisms that are separated and unable to exchange genetic materials with other organism of the same species.
Geographical Isolation may be a result of coincidence or accident.
Here are some factors of Geographical Isolation:
1) Isolation by barriers
2) Isolation by distance
3) Isolation after an Event
4) Isolation by separation
