Answer:
Ok, I am going to try my best to label all of this. It is quite a vague drawing, isn't it? lol, lets see:
A - Lysosome
B - Endoplasmic Reticulum
C - Golgi Bodies?
D - Cell Membrane
E - Nucleus
F - Ribosomes
G - Cytoplasm
H - Mitochondria
Thank you very much! If you need any more help or such, make sure to comment, and I'll try to help some more. Thank you!
It's the nucleus as it contain the DNA
Answer: Option E) polar
Amino acid-derived and peptide hormones are unable to diffuse across a cell membrane because they are polar
Explanation:
Amino acid-derived and peptide hormones such as serotonin, epinephrine, dopamine etc, are unable to diffuse across a cell membrane because they consist of several repeating units of amino acids with positively charged or negatively charged side chains.
Thus, the side chains make these hormones water-loving (hydrophilic), and impassable to the hydrophobic layer of the cell membrane.
Answer: A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.
