Answer:
1. First of all, a squirrel would make sure to stash lots of food before and during the winter.
2. The squirrel would claim its own tree hollow/burrow.
3. They wrap themselves into a tight ball and go into a state of torpor (Torpor is a state where their body temperature becomes about the same temperature as their surrounding hibernaculum. This causes their heart rate to slow and causes them to use less energy)
4. Squirrels get up after 20 or so days to rewarm themselves up, and perhaps eat something to regain their energy. After that they will head back to their hibernaculum to continue hibernation.
5. When spring approaches they will fully wake up, go eat, regain their energy, and prepare themselves for the mating season.
Hope this helps :)
Answer:
D
Explanation:
The rest of the options are learned, and are not adaptations.
Adaptations help an organism survive in an environment.

<span>The correct answer is that cholesterol is
steroidal alcohol.</span>
Cholesterol is an important organic molecule biosynthesized by all animal cells because it is an essential structural component of cell membranes. Its function in the membrane is to maintain membrane structural integrity and fluidity and to change cell’s shape rapidly. Cholesterol is a precursor for the biosynthesis of steroid hormones and vitamin D and bile acid.
Answer:
A
Explanation:
*Not sure about this answer
Cellular respiration included the metabolic pathways of glycolysis, the Krebs cycle, and the electron transport chain is described below.
Explanation:
1. Catabolism of glucose in glycolysis and pyruvate oxidation-Produces NADH for use in ETC.Produces acetyl-CoA for entry into kerbs cycle.Provides energy for phosphorylation of ADP.
2. Oxidation of intermediates in the Krebs cycle-Produces NADH or FADH2 for use in ETC.Releases high energy electrons for use in ETC.Provides energy to pump protons against their concentration gradient.Produces GTP for phosphorylation of ADP.
3. Formation of a proton gradient by the electron transport chain-The flow of protons through membrane-bound ATP synthase generates ATP.Provides energy for phosphorylation of ADP.
