Students observe woodchucks in their area. In the summer, students observe that woodchucks eat a lot of plants. In the winter, students observe that woodchucks live in their burrows and are seen less often. The picture shows a woodchuck in its burrow.
Which change that helps a woodchuck survive the winter did students observe?
O A Woodchucks migrate to survive the winter.
O B. Woodchucks hibernate to survive the winter.
O c. Woodchucks eat a different kind of food in the winter.
O D. Woodchucks grow thicker fur to keep them warm in the winter.

The correct answer is - B. Woodchucks hibernate to survive the winter.

Explanation:

Many mammals such as groundhog or also known as woodchucks hibernate during winter in order to survive winter. Hibernation is the process or state of minimal activity during a particular time of the year characterized by low body temperature, slow heart rate, and low metabolic rate.

Woodchucks are become less active and remain in their burrow and seen very little during the winter and stay like this till late winter or early spring.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
