Answer:B. is false
Explanation:
Once RNA polymerase and its related transcription factors are in place, the single-stranded DNA is exposed and ready for transcription. ... Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA.
A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years. And if the star is very small, with a mass only a tenth that of the Sun, it can keep fusing hydrogen for up to a trillion years, longer than the current age of the universe.
Answer:
Half would have the genotype Aa.
Explanation:
Given that the genotype of both of the parents was "Aa"; both parents would make two types of gametes. The 50% gametes from each parent would carry allele "A" while the rest 50% gametes from each parent would carry allele "a".
The random fusion of gametes of two parents would give the progeny with genotype ratio 1/4 AA: 1/2 Aa: 1/4 aa.
All living things are made up of cells.
<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.
