Concentration of NAD+ (umol/L) 4 8 12 16 20 Concentration of Lactic Acid (mmol/L) OHHHHHHHHHHHHHHHHHHHH 4 8 12 16 20 Time (weeks) Figure 2. The concentration of NAD* (top) and lactic acid (bottom) in the blood of a representative treated individual (a) Describe the pattern of inheritance that is most likely associated with a mutation in the MT-ND5 gene. Explain why individuals are not typically heterozygous with respect to mitochondrial genes. (b) Identify a dependent variable measured in the researcher's experiment. Identify one control that the researcher could use to improve the validity of the experiment. Justify the researcher analyzing blood samples at many intermediate time points instead of at only the beginning and the end of the 20-week period. (c) Describe the relationship between the concentration of NAD in the blood and the concentration of lactic acid in the blood during the first 5 weeks of treatment with the vitamin. Based on Figure 2, calculate the average rate of change in blood NAD concentrations from week 5 to week 17. (d) The researcher performed a follow-up experiment to measure the rate of oxygen consumption by muscle and brain cells. Predict the effect of the MT-ND5 mutation on the rate of oxygen consumption in muscleand brain cells. Justify your prediction. The researcher had hypothesized that the addition of the vitamin that is similar in structure to NADH would increase the activity of the mutated NADH dehydrogenase enzyme in individuals
I believe that the answer is Cells or carbon.
Answer:
a. a very cold ecosystem, because they would lose too much body heat
Explanation:
<em>Ectotherms would be l</em><em>east common in very cold ecosystem, because they would lose too much body heat.</em>
Generally, ectotherms are organisms whose internal physiological temperature requirement depends on external sources. They generate very little heat internally and as such, rely on heat sources in the environment for the necessary physiological heat for their bodies.
Consequently, ectotherms live in environments where temperature are more or less constant or constantly seek out external sources of heat for their bodies.
<u>In a very cold environment, the opportunity to seek out external source of heat would not be possible for ectotherms, and body heat would be lost to the environment in the process of maintaining constant body temperature. Hence, they are least likely to occupy this kind of environment.</u>
<em>The correct option is </em><em>a.</em>
