Carnivorous mammals, on the other hand, usually have long, sharp teeth that help them grab prey and rip it apart. A group of herbivores called ruminants have specialized stomachs.
Explanation:
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:
The stem, which has two parts. The inner tissue is known as the xylem. It moves water and minerals from the roots to the leaves. The outer tissue is the phloem , which transports food from the leaves to the rest of the plant through a process known as translocation
The stem of a plant has two parts, Xylem (inner tissue) and Phloem (the outer tissue).
