Just because that planet does not have the kind of gravity we have and the atmosphere can trap heat but to make a green house effect you will need time.
Answer:
crossing over, process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. Crossing over occurs in the first division of meiosis . At that stage each chromosome has replicated into two strands called sister chromatids. The two homologous chromosomes of a pair synapse, or come together. While the chromosomes are synapsed, breaks occur at corresponding points in two of the non-sister chromatids, i.e., in one chromatid of each chromosome. Since the chromosomes are homologous, breaks at corresponding points mean that the segments that are broken off contain corresponding genes , i.e., alleles. The broken sections are then exchanged between the chromosomes to form complete new units, and each new recombined chromosome of the pair can go to a different daughter sex cell. Crossing over results in recombination of genes found on the same chromosome, called linked genes, that would otherwise always be transmitted together. Because the frequency of crossing over between any two linked genes is proportional to the chromosomal distance between them, crossing over frequencies are used to construct genetic, or linkage, maps of genes on chromosomes. Mutations , temperature changes, and radiation all affect crossing over frequency. Under the microscope, a crossover has the appearance of an X and is called a chiasma.

To answer this question we need to remember quickly how the carbon cycle works, a part of the free carbon dioxide in the atmosphere is captured by plants through photosynthesis, other dissolves into water bodies, and some more remains in the atmosphere. This fixated carbon by plants passes to animals where can integrate into the soil or be released again into the atmosphere. The carbon that remains in the soul can form fossil fuels that are used by humans in the industry and released once more to the atmosphere. Therefore taking this into account we can say that that order is as follows:
Photosynthesis: Plants
Burning oil and coal: Factories
Respiration: Animals
Decomposers: Fossil fuels
Answer:
Both
Explanation:
A person's skin color, hair color, dimples, freckles, and blood type are all examples of genetic variations that can occur in a human population. Examples of genetic variation in plants include the modified leaves of carnivorous plants and the development of flowers that resemble insects to lure plant pollinators. Even though in artificial selection, you take which genes are desired it is still passing genetic variation through offspring.
