Answer: False

Explanation:

DNA sequences can be similar for organisms that are related to each other but through various steps of meiosis like crossing over and law of independent assortment we can get genetic variations that lead to slight differences. We can also get differences in DNA sequences due to mutations.

Komok [63]

Answer:

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = $\frac{(O - E)^2}{E}$ where O = observed frequency and E = expected frequency

Chamber O E Chi-square

A 18 10 $\frac{(18 - 10)^2}{10}$ = 6.4

B 2 10 $\frac{(2 - 10)^2}{10}$ = 6.4

Total Chi-square = 6.4 + 6.4 = 12.8

Degree of freedom = 2 - 1 = 1

Tabulated Chi-square (α = 0.05) = 3.8415

The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.

The correct option is c.

Which respiratory function describes the exchange of oxygen and carbon dioxide in the cells?.

9966 [12]

Answer:Cellular Respiration

Explanation:

Cellular respiration is the process by which cells produce energy, and is broken down into three more steps: glycolysis, Kreb’s cycle, and electron transport chain. Glycolysis requires glucose, two ATP, and NAD+, and two ADP, and produces two pyruvate, four ATPs, two NADH, and two H2O. The Kreb’s Chcle and thus the downstream electron transport chain require acetyl-CoA, one ADP, three NAD+, and one FAD, but pyruvate oxidation needs to happen prior to the Kreb’s Cycle, thus this is where the Oxygen is used and produced into two CO2.
