Answer: The correct answer is-

b. a gene has undergone a change in the organisms DNA.

DNA ( deoxyribonucleic acid) contains instructions for protein synthesis in the form of codons ( a sequence of three nucleotides), which code for particular amino acid. DNA is converted to mRNA ( through transcription), which is then converted to proteins ( through translation).

As per the question, a mutation in an organism has lacked the ability to make ( incorporate) one amino acid.

This means that there is a change in the codon ( that is change in the gene) in a manner such that now the mutated codon will not code for any amino acid.

Thus, option b) is the right answer.

PolarNik [594]

<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

Precision refers to the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.  

Accuracy refers to the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 32 kg and one person weighed 31 kg and another person weighed 29 kg. Then, the weight measured by first person is more accurate.

According to the question:

Mass weighed by Mary = 10.00 g

Mass weighed by Tommy = 10 g

As, mass weighed by Mary is reported upto 2 decimal places. Thus, it is more precise.

Hence, the correct answer is Option C.

Please help me How do the biotic factors vary within an ecosystem and why?
DochEvi [55]

Answer:

Biotic factors are just everything living (bio-) in an ecosystem. So they're bound to vary in every ecosystem, based on the biome, climate, other food sources available, et cetera.

Do you see flamingoes in the forest? No, you say? Well, they're living; they're biotic factors. They aren't in a forest or a jungle ecosystem because that's not their habitat and they don't thrive there.
