Answer:
All organisms that have life, both plants and animals.
Explanation:
You didn't provide an illustration, but I guess I can still help. Biotic factor means that it has life, abiotic means it's not alive (hence the a- at the beginning.) Some biotic factors of a pond ecosystem include: earthworms, fishes, frogs, plants and insects.
Answer:
To produce wood and paper products.
Explanation:
Water is used in factories to make both wood and paper products.
I hope this helps!
Answer:
The answer is very likely C.
Explanation:
This becomes easy once we remember that DNA and RNA are not identical - which is why they have different names, RNA = 'ribo', DNA = 'deoxy.' This eliminates choice (A). While they are different, they are not incredibly different - DNA and RNA are both made up of nucleotides - they are not however, made up of Amino acids. Amino acids are what they can <em>code</em> for, and subsequently create proteins during protein synthesis. This helps us eliminate (B). Finally, we know that in order for something to have base <em>pairs</em> it needs to be double stranded - which RNA is not. Which means that because RNA is not double stranded (its singly stranded) that the answer cannot be (D). Leaving us with the only plausible option; (C).

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
Answer:
Let's assume curly hair is the dominant trait and trait hair is the recessive trait.
Therefore, our cross is AA x aa. Drawing a Punnett square will then give us all heterozygous individuals.
there for all offspring with have wavy hair
