Answer:Alllopatric speciation.
Explanation:
This is the type of speciation in which organisms of the same species are separated from each other by geographical barrier (isolated) to the extent that the selective pressures in individual environment affected their gene flow.
Therefore , if the these organism mated when reunited,they will not be able to produce offspring.
It is also known as Geographical speciation. Therefore new species of organisms have emerged.
This is speciation.
The answer is fertilization.
Fertilization is the process in which two gametes fuse which
first creates a zygote and then leads to the development of an embryo. Pollination is a transfer of male pollen to the female reproductive organ. By reaching there, male gamete and female gamete will fuse which represents fertilization. So, pollination is <span>an important step in the fertilization of flowering plants.</span>
Photic and aphotic I think?
Answer:
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...
