Consider the following claim about how a female long-tailed sun skink can increase her
reproductive success:
Guarding the nest increases the chances that the female's eggs will hatch.
Which of the following observations best supports the claim?
Fewer eggs are eaten when females keep egg-eating snakes away from the
eggs in their nests.
Many egg-eating snakes attack and try to eat the eggs in female skinks'
nests.
Some females stay at their nest with their eggs for several days after laying
them.



Answer :

The observation that best supports the claim that guarding the nest increases the chances of the female long-tailed sun skink's eggs hatching is: 1. Fewer eggs are eaten when females keep egg-eating snakes away from the eggs in their nests. This observation directly connects the act of guarding the nest with a positive outcome, which is the protection of the eggs from predators like egg-eating snakes. By keeping these predators away, the female skink increases the likelihood that more eggs will survive and hatch successfully. This behavior enhances the reproductive success of the female skink by safeguarding her offspring.
