(Initial individuals + newborn individuals) - dead individuals = total individuals
Growth rate = (total individuals/initial individuals) * 100
Population growth rate = new percentage minus 100%
Calculations
(1000 + 500) - 200 = 1500 - 200 = 1300
Growth rate = (1300/ 1000) * 100
= 1.3 * 100
= 130%
Population growth rate = 130% - 100%
= 30% per year if it is uniform
Answer:
Nitrogen
Explanation:
The nitrogenous bases of the two separate polynucleotide strands are bound together, according to base pairing rules (A with T and C with G), with hydrogen bonds to make double-stranded DNA.
I'd say first question, "life changes over time".
Second question, "when there are physical similarities in the early stages of embryonic development, it suggests that each of the modern organisms once had a common ancestor".
Third, appendix.
Fourth, "they are evidence that all came from a common ancestor and that life changed over time for all these organisms to exist".
Fifth, "they all share at least 50% of the same DNA arrangement".
I might be a little late but hopefully this helps!
Covalent bonds are formed when two non metal atoms share an electron. The atoms either give up or gain an electron, due to the outer shell being unstable.
C.they separate atria from ventricles, and ventricles from the large arteries that leave them.
