I would guess rainforest because it’s an reptile/amphibian it appears and those animals need water to survive. There isn’t much water in the dessert.
Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.
Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
Answer:
you already answered it I'm confused lol
Answer:
Rabbits are adapted to a certain type of environment and conditions, not certainly winter. So this effect the survival rate of the rabbits.
Moreover, their diet intake may be affected, for example, they are herbivores, so the plants they consume might not be present in this harsh season.
Then, competition with other animals increases as well, so the rabbits might have more predators.
