A certain species of desert lizard digs tunnels in which to lay its eggs. The eggs must incubate inside the tunnel for several w
eeks before hatching, and they fail to hatch if they are disturbed at any time during this incubation period. Yet these lizards guard their tunnels for only a few days after laying their eggs. Which of the following, if true, most helps explain why there is no need for lizards to guard their tunnels for more than a few days?(A) The eggs are at risk of being disturbed only during the brief egg-laying season when many lizards are digging in a relatively small area.(B) The length of the incubation period varies somewhat from one tunnel to another.(C) Each female lizard lays from 15 to 20 eggs, only about 10 of which hatch even if the eggs are not disturbed at any time during the incubation period.(D) The temperature and humidity within the tunnels will not be suitable for the incubating eggs unless the tunnels are plugged with sand immediately after the eggs are laid.(E) The only way to disturb the eggs of this lizard species is by opening up one of the tunnels in which they are laid.
a. The eggs are at risk of being disturbed only during the brief egg laying season when many lizards are digging in a relatively small area.
Explanation:
Lizards work like this, some species have egg to reproduce the babies, in this case, the lizard just stay some days to watch that there are no possible risk for the eggs. If the animal is completely sure that is a safe and a good place to leave the eggs, the lizard continue to do its own life.
After some months, the baby lizard need to figure out how to survive in this new world, as his/her mother did. They need to use its instinct.
