There was less of it, making it more possible for the species to be extinct.
The answer would be <span>B. Abiotic factors

Answer: The cell that is being observed under the microscope have flagellum and lysosomes. The function of flagella is to help in the movement of the cell. This is considered as the locomotory organ of the cells. The membrane bound cell organelles lysosomes contains hydrolytic enzymes that is used by the cell for the breakdown of food ingested by cell.
Conclusion is that the cell can perform locomotion and digestion of small molecules.
<span>The ribosomal RNA is especially useful for the study of phylogenetic relationships because ribosomal RNA are highly conserved.
It is very less that is why it is easy to compare. Ribosomal ribonucleic acid is the RNA component of ribosome which is essential for protein synthesis to all living organisms.
rRNA is widely used for the purpose of working out evolutionary relationships which are among organisms. </span>
The correct answer is C
<span>Erwin Chargaff's research found that there are two pairs of nucleotides in the DNA molecule, adenine-thymine, and guanine-cytosine.
Those two pairs of nucleotides are complementary and since they pair up in the DNA molecule, the amount of one nucleotide in the pair must be equal to the amount of the other nucleotide of the pair.
He also found that different species have different proportions of nucleotides, which proved that DNA is the carrier of genetic information, not the proteins.</span>
