  1. Dogs are animals.

  2. Dogs are mammals.

  3. Dogs are reptiles.

  4. Dogs are birds.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The syllogism uses the logical rules of deduction to establish that dogs, being a subset of mammals, must also be a subset of animals.

Multiple choice

Multiple choice

Which group of microorganisms is known for their ability to survive in extreme environments, such as hot springs and deep-sea hydrothermal vents?

  1. Bacteria

  2. Archaea

  3. Fungi

  4. Protists
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Archaea are extremophiles, meaning they can thrive in extreme conditions that would be lethal to most other organisms.

Multiple choice

Which of the following is NOT a common type of injury treated by wildlife rehabilitators?

  1. Broken bones

  2. Lacerations

  3. Burns

  4. Poisoning
Reveal answer Fill a bubble to check yourself

Multiple choice

Which of the following is NOT an example of convergence?

  1. The wings of birds and bats

  2. The eyes of humans and octopuses

  3. The streamlined bodies of dolphins and sharks

  4. The opposable thumbs of humans and chimpanzees
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The opposable thumbs of humans and chimpanzees are an example of homology, not convergence. Homology refers to the similarity of structures due to shared ancestry, rather than due to similar selective pressures.

Multiple choice
