Answer: B
One template strand can only serve to synthesise 1 new strand of DNA at a time.
Answer:
The chromosomes are pulled away from one another from the metaphase plate. Subsequently, all the chromosomes to 1 side are pulled one way, and all the chromosomes on the opposite side are pulled the other way. In the long run, every haploid cell would possibly contain either just maternal or fatherly chromosomes if traverse didn't happen.
The characteristic that relies is using energy
Answer:
they obtain their energy from the sun and water and pollen
Explanation:
Sorry if I'm wrong have a good one!
Answer:
C) The ancestral population probably had this type of blood pigment, but it was lost through genetic drift in the other 29 populations.
Explanation:
The presence of a blood pigment that is extraordinarily effective at carrying oxygen is a beneficial genetic trait and should be favored by natural selection. According to the given information, the organisms of only a single population of pupfish have this trait while the others do not have it.
This means that the trait was present in the ancestral populations of the pupfish but was lost in the other populations due to some accidental/chance event. Loss or fixing of an allele by a chance event is called genetic drift. It does not include any natural selection but results in a random change in the allele frequencies of a population. Therefore, loss of the trait by genetic trait might have occurred in the other populations.
