Chargaff's rules state: adenine is complimentary to thymine and cytosine is complimentary to guanine. For this question, in order for polymerization of the growing complementary strand, guanine must bind with cytosine.

Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
if they are all part of the same species it would be a population
Answer: The complementary strand is TCC- GAT - TTG
Explanation: During DNA replication, each strand of the DNA serves as a template for the synthesis of a new strand, thereby producing two new DNA molecules, each with one new strand and one old strand. A template is a DNA strand that would allow nucleotide molecules to be lined up in a specific order and be joined to create another DNA with a unique sequence. This results in creation of a double stranded DNA in which each strand is complementary to the other. In nucleotide base pairing, Guanine pairs with Cytosine while Thymine pairs with Adenine.
G = C while T = A.
Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
