Answer:
CGUAUGUCA
Explanation:
Firstly, the strand in the question is a DNA strand because it contains the Thymine base, which is only found in a DNA molecule. The process of changing a DNA molecule into RNA molecule (specifically a messenger RNA) is called transcription. Transcription is done using the complementary base pairing rule, which states that Adenine (A) will always pair with Thymine (T), and Guanine (G) will always pair with Cytosine (C).
In the case of transcription, the Thymine bases will change to Uracil (U), since Uracil is only found in the RNA molecule. That is, A-U and G-C. Hence, a DNA strand that reads: GCATACAGT will produce a mRNA strand CGUAUGUCA.
The answer of the absolute refractory period is 3.5
This diagram seems to begin with Multicellularity. So, as you follow the line, the next is tissues, then three-germ layers, bilateral symmetry
So, right before 3 germ layers is tissues
So, the answer is D
