Andrea became highly aroused and alert when she was stung by a bee thanks to the activation of her reticular formation. Recticular formation is a nerve network of nuclei clusters found in the human brain stem. It has projection to the thalamus and cerebral cortex that allow it to exert some control over which sensory signals reach the cerebrum and the conscious of the body.

<em>B. One parent organism and no egg or sperm.</em>
Explanation:
In asexual reproduction, an organism can produce offspring with no gametes involved (eggs or sperm), and does not need to undergo meiosis.
If an organism produces offspring through asexual reproduction, all of the DNA from the parent will go to the offspring. Since there is only one parent, meiosis will not occur since there is no need for genetic differentiation.
All of the organisms produced by the parent during asexual reproduction will be identical to the parent. They will have the same DNA and genetic make up.
