Answer: <span>A) Slow to repopulate
------
Genetic variation is an advantage of sexual reproduction. It increases survival and the ability to adapt in a species. Species with genetic variation can respond better to environment changes, since the genetic variability allows some to be immune to disease or adapt better to a change, and live to reproduce.
Slow to repopulate is a disadvantage because the species cannot recover quickly after a large disaster. It also means they cannot adapt as quickly to an environmental change.</span>

<h3>
How toilets can prevent spread of disease?</h3>
- Toilets save lives! Deathly infections proliferate quickly in an absence of restrooms. Every day, over 750 kids under five pass away from diarrhea brought on by contaminated water, subpar sanitation, and bad hygiene.
- Girls who attend schools without restrooms may fall behind in their studies. Many students are compelled to skip school while they are on their period because there are inadequate sanitary facilities.
- Toilets are an excellent purchase. According to data by the WHO, every dollar spent on cleanliness has a return of $5.50 USD.
- However, 892 million individuals practice open defecation, which involves going outside and defecating in bushes, on the side of the road, or in garbage piles.
- 90% of those who use open defecation live in rural areas, therefore it's frequently a question of where they are located.

Answer: C. Black snakes will not prey on cane toads in areas where cane toads have been present for 40–60 years.
Explanation:
Cane toad secret a toxin called bufotoxin which is a defense mechanism against predators. These defense mechanism is capable of killing black snakes if they eat cane toads. Within a period of 40 to 60 years, the black snakes in these area will be aware of the presence of a toxin capable of killing them in cane toads and will not prey on them. This phenomenon is termed learned behavioral adaptation.
