Since the sun is only out during the day, the heat from the sun warms up the temperature, longer days means more sun time, more sun time means more heat
Answer:
the branch of science concerned with classification, especially of organisms; systematics.
Explanation:
Answer:
Water slips between cracks in rocks on earth this is called weathering but on the moon there is no water so this cannot happen.
Answer:
C. Beak size is an inherited trait in the finch population under study.
D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.
E. Beak size varies among the birds in the finch population under study.
Explanation:
The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.
If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.
Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.
Answer: They have both RNA and DNA
Explanation: Rickettsiaceae possess both nucleic acids RNA and DNA, this is a distinctive characteristics of the organism. They are pleomorphic organisms and are mostly gram-negative organisms.
Rickettsiaceae are infectious to arthropods therebygiving making them an intermediate host or carriers and human can be infected via biting from infected arthropods.
