an asteroid impact
Explanation:
The asteroid that formed a crater located on the edge of the Yucatan peninsula thought to be responsible for the mass extinction of dinosaurs.
Serotonin and n<span>orepinephrine.
Serotonin decreases appetite by activating </span>5-HT2C receptors<span> on dopamine-producing cells which will cause dopamine release to stop. Dopamine is responsible for the increase of appetite, therefore, serotonin decreases appetite.
Norepinephrine by increasing the production of glucose it also causes the body to feel satiety and, therefore, decreases the appetite.</span>
Explanation:
Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!
When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.
When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.

If the cell treated with a chemical that inhibits DNA synthesis is treated to undergo the process of the cell cycle, the phase that will be affected is the S-phase of interphase.
<h3>What is interphase?</h3>
The interphase stage of cell division is the resting stage between two successive divisions.
The interphase is further grouped into three phases namely:
- G1 phase
- S-phase or synthesis phase
- G2 phase
The synthesis phase of interphase is the stage where new DNA strand is synthesized, hence, if the cell treated with a chemical that inhibits DNA synthesis is treated to undergo the process of the cell cycle, the phase that will be affected is the S-phase of interphase.
