Answer:
See the answer below
Explanation:
<em>The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.</em>
The problem of transporting the messenger RNA is solved by two features of the cell:
- The presence of pores in the nuclear envelop
- The presence of transport proteins in the nucleus
<u>The mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP. </u>

A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to offspring. This particular individual has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease. They are referred to as genetic carriers. The chance of two carriers having an offspring with the disease or genetic disorder is 25%
Most climate scientists agree the main cause of the current global warming trend is human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.
Based on this exert, I'd say Option C
