This dispersal reduces the likelihood that a sperm will find an egg. Many sperm and eggs die before achieving fertilization. The low success rate of external fertilization puts animals at a reproductive disadvantage compared to internal fertilization.
Answer:
i would say claws, larger sharp teeth, and some my have camouflage in order to hunt better.
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.
The primary function of cellular respiration is to break down food molecules and generate ATP.
<h3>What is cellular respiration?</h3>
Cellular respiration is the process by which living organisms obtain energy in form of ATP by breaking down food molecules in their cells.
Cellular respiration occurs in all living organisms because energy is required for their daily metabolic activities.
Therefore, the primary function of cellular respiration is to break down food molecules and generate ATP.
