Answer:
mRNA: A-U-G-C-A-U-U-A
Explanation:
Given DNA template: T-A-C-G-C-T-A-A-T
Newly transcribed mRNA: A-U-G-C-A-U-U-A
Transcription is a process that uses DNA template strand to make RNA strands. The process occurs in nucleus. The nucleotide sequence of DNA template is always complimentary to its respective RNA sequence.
Here, thymine of DNA template strand pairs with adenine of newly formed RNA. Adenine of DNA template would pair with uracil of RNA. Guanine of DNA template pairs with cytosine.
Diatoms contain chloroplasts that have four membranes. These four membranes are evidence of secondary endosymbiosis (Option c).
<h3>What is secondary endosymbiosis?</h3>
Secondary endosymbiosis is a hypothesis used to explain why diatom chloroplasts have four membranes.
According to this hypothesis, diatoms received different genes from distinct photosynthetic and non-photosynthetic ancestors.
The acquisition of genes of different ancestors led to diatoms having chloroplasts with four membranes.

Correct answer - Frequency.
Why? - The frequency, is the number of waves that pass a certain point in a specified amount of time.
