Answer:
In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.
In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.
Explanation:
B. Ribosomes, their function is to assemble Amino Acids into protein chains
Answer:
"Endocrine Organs and the Nervous system II. Nerves and hormones work together to regulate function of the human digestive system; they control muscular contractions and the rate of secretion from digestive organs. ... Several hormones coordinate digestive functions of the stomach, pancreas and gall bladder."
Explanation: :)
<span>An example of
chemical weathering is an acid dissolving limestone. This is because an acid is
a product of industrial and chemical processes that is used in a lot of
commercial practices. It can dissolve limestone because the main component of
limestone is calcium carbonate. Reacting
this with an acid produces a carbon dioxide gas. Water breaking rocks is an
example of physical weathering. Plant roots splitting rocks is an example of
biological weathering. Wind breaking own rock is an example of physical weathering.</span>
