BRAINLIEST 1) What are the differences between artificial and natural selection?

2) What are the similarities between artificial and natural selection?

3 )How can environmental changes impact natural selection and adaptations?

4) When can extinction occur?

1. artificial is done by humans, doesn't result in evolution or speciation and is a faster process

natural is random changes in the genotype of an organism that increase the change of the organism surviving and procreating thus passing on their genotype to the next generation

2. both can result in genotype and phenotype changes within a population

3. the environment and organisms are in constant relationship, as the environment changes the individual organisms within that environment that are best suited in a heritable way will survive and procreate more thus increasing the suitability of the population to the current environment

4. anytime a species is not able to replace it's numbers successfully, could be caused by environmental changes, predation pressures etc

Explanation:

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
