Question

both polar bears and gazelles have internal and external structures that help them survive. what are two structures that both animals need to survive? select the two correct answers. (1 point) long legs to run away from predators thick blubber to stay warm fur that helps the animal blend in with its environment claws for hunting a digestive system to obtain energy and nutrients

Explanation:

Brief Explanations
  1. Analyze each option:
  • "long legs to run away from predators": Polar bears don't rely on long legs to run from predators (they are apex predators in their environment), and gazelles use long legs to run from predators, but polar bears don't, so this is incorrect.
  • "thick blubber to stay warm": Polar bears have thick blubber, but gazelles (being mammals of grasslands) do not have thick blubber, so this is incorrect (the original selection here is wrong as per the question's requirement of structures for both).
  • "fur that helps the animal blend in with its environment": Polar bears have white fur to blend in with snow/ice, and gazelles (e.g., some species have fur that blends with grasslands) also have fur that helps them camouflage in their environment. This is a valid structure for both.
  • "claws for hunting": Polar bears have claws for hunting, and gazelles do not use claws for hunting (they are prey animals, use legs for running), so this is incorrect.
  • "a digestive system to obtain energy and nutrients": All animals (including both polar bears and gazelles) have a digestive system to obtain energy and nutrients. This is a valid internal structure for both.

Wait, the question says "internal and external structures that both animals need to survive". Let's re - evaluate:

  • External structures: "fur that helps the animal blend in with its environment" (external) is correct for both (polar bear: white fur in arctic; gazelle: fur color matching grassland).
  • Internal structures: "a digestive system to obtain energy and nutrients" (internal) is correct for both (all animals need to digest food for energy).

But looking at the options, the two correct ones should be "fur that helps the animal blend in with its environment" and "a digestive system to obtain energy and nutrients". However, in the given options, maybe there was a mis - selection earlier. Let's check again:

Wait, the original selected options were wrong. Let's correct:

  • "long legs to run away from predators": Polar bears don't need this (apex predator), gazelles do. So no.
  • "thick blubber to stay warm": Gazelles don't have blubber. So no.
  • "fur that helps the animal blend in with its environment": Yes, both have fur for camouflage.
  • "claws for hunting": Gazelles don't hunt, so no.
  • "a digestive system to obtain energy and nutrients": Yes, all animals have a digestive system.

So the two correct answers are "fur that helps the animal blend in with its environment" and "a digestive system to obtain energy and nutrients". But in the given options, if we consider the choices:

Wait, maybe the question's initial selected options were incorrect. Let's re - assess the question's requirement: structures (internal or external) that BOTH polar bears and gazelles have for survival.

  • "fur that helps the animal blend in with its environment": External structure, both have fur that camouflages them in their respective habitats.
  • "a digestive system to obtain energy and nutrients": Internal structure, both are animals and need to digest food.

The other options:

  • "thick blubber to stay warm": Gazelles don't have blubber.
  • "long legs to run away from predators": Polar bears don't need to run from predators.
  • "claws for hunting": Gazelles don't hunt.

So the correct options are:

  • fur that helps the animal blend in with its environment
  • a digestive system to obtain energy and nutrients

But in the given checkboxes, the originally selected "thick blubber..." is wrong. The correct selections s…

Answer:

  • fur that helps the animal blend in with its environment
  • a digestive system to obtain energy and nutrients
