Question

Accepted Answer

### Sub - question 1
# Brief Explanations:
To answer this, we recall mammal - specific traits. Mammals have three middle ear bones (malleus, incus, stapes), which not all vertebrates have. They have hair or fur (unique to mammals among vertebrates in a defining way) and females have mammary glands to nurse young (not all vertebrates have this).
# Answer:
Three characteristics common to all mammals but not all vertebrates: 1. Presence of hair or fur. 2. Presence of mammary glands in females to produce milk for offspring. 3. Having three middle ear bones (malleus, incus, stapes).

### Sub - question 2
# Brief Explanations:

### Sub - question 9
# Brief Explanations:
The tallest living animal is the giraffe (Giraffa spp.). Giraffes have long necks and legs, which make them the tallest land animals.

# Answer:
The four stomach chambers of a ruminant are the rumen, reticulum, omasum, and abomasum.

### Sub - question 11
# Brief Explanations:
Three groups of even - toed ungulates (Artiodactyla) are deer (family Cervidae), cattle (family Bovidae), and pigs (family Suidae).
# Answer:
Three groups of even - toed ungulates: 1. Deer (family Cervidae). 2. Cattle (family Bovidae). 3. Pigs (family Suidae).

### Sub - question 12
# Brief Explanations:
