Answer: 1.9 million species
Explanation: I looked it up
I think it stands for Gap. Do you mean G1 and G2 interphases?
It seems that you have missed the necessary options for this question, but anyway here is the answer. Glaucoma has been one of the leading causes of blindness and a common form has been linked to three genes and more that 20 genetic loci. So the statement that best describes glaucoma is that, <span>a polygenic trait that is influenced by the number of alleles present. Hope this answer helps.</span>
In the endosymbiont theory, an engulfed prokaryote that could perform respiration evolved over the generations into mitochondria providing the cell with an efficient means of producing ATP from organic compounds.
Similarly, an engulfed prokaryote that could perform photosynthesis evolved over the generations into chloroplast providing the cell with sunlight-generated sugar.
Explanation:
Endosymbiosis is the mutual relationship between two organisms. The theory explains that eukaryotes have evolved from prokaryotic cell or organism.
The host eukaryotic cell engulfed bacteria or prokaryote as bacteria was once an independent entity which could perform cellular respiration and photosynthesis. Possibility of one more cell which engulfed other cells is there.
Mitochondria have its own DNA and is the centre of ATP production which suggests that mitochondria has evolved over the time by photosynthetic bacteria. Sequence analysis also suggest that mitochondria had evolved from eubacteria.
The bacteria integrated into plant cell able to perform photosynthesis has evolved in to chloroplast int the plant cells.
