Explanation / Answer

1. c.

Rattlesnakes can see the infrared light- This statement is false. They can`t see it.

Rattlesnakes are ovoviviparous, which means that eggs incubate inside the mother’s body. Babies are born live, encased in a thin membrane that they puncture after being born.

Rattlesnakes are large, venomous snakes.

Their namesake rattle is a highly effective warning sign, signaling predators to stay away. “Rattles are segments of keratin that fit loosely inside one another at the end of the snake’s tail,”

2.c All tortoises and turtles are monogamous.

turtles are mainly monogamous, with females storing sperm from one male and using it to fertilise multiple egg clutches.

Paleontological and morphological studies place turtles as either evolving from the ancestor of all reptiles or as evolving from the ancestor of snakes, lizards, and tuataras.

Tortoises live on land. Turtles can live in water or land, with some species being almost solely aquatic.

Many turtles and tortoises lay more than a single clutch of eggs each year

4.b.Caecilians are tropical amphibians that look like large worms or slick snakes. They have no arms or legs, and sometimes it's hard to tell which end is the head and which is the tail.

5.c.Crocodilians and snakes are entirely carnivorous, and many of them can eat very large animals as prey.
