Answer: mRNA moves through pores in the nuclear membrane
Explanation: nuclear membrane pores permit the passage of mRNA, but only after processing within the nucleus. The non-coding parts of the RNA are deleted (introns), the 5’ end capped to prevent premature degradation, and a string of A nucleotides added at the 3’ end (improves stability).
It is not c or d. I think it is a.
Answer:
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Botox blocks signals from the nerves to the muscles. The injected muscle can no longer contract, which causes the wrinkles to relax and soften. It is most often used on forehead lines, crow's feet (lines around the eye) and frown lines. Wrinkles caused by sun damage and gravity will not respond to Botox.
Complete question:
Which survivorship curve best describes most marine organisms (few adults produce a large number of eggs and larvae).
- Type I
- Type II
- Type III
- None of the above
Answer:
<em>Type III </em>
Explanation:
There are three survivorship curves, each of them corresponding to different species according to their reproductive strategies.
- <u>Type I</u><u>.</u> Organisms do not tend to die when they are young or middle-aged, but they do when they are old. These species, in general, have a few descendants and parents provide much parental care to ensure their progeny to survival.
- <u>Type II.</u> Organisms that have more or less the same probabilities of dying in each age interval. These organisms can also have a few descendants and they can provide significant parental care.
- <u>Type III</u>. Only a few individuals survive their first period of life or their firsts years. However, the lucky ones to reach a certain age generally have a long life. These organisms have a lot of descendants at the same time, but they do not provide much parental care. This is the case of most marine organisms that produce a large number of eggs and larvae when they are adults, but they do not provide parental care.
