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:
b) there are 56 deer in 1000 acres of area.
Explanation:
If a person has 1000 aces of land and a local wildlife biologist tell him that on every 18 acres only one deer is present so in 1000 acres there are 56 deer are present.
calculation;
1 deer ------ 18 acres
x --------- 1000 acres
by cross multiplication, we get
18 x = 1000
both side divided by 18, we get
x = 55.5
by rounding off we get
x = 56
