Question 1

What are the general characteristics of organisms in kingdom animalia

Answer 1

Heterotrophic, Multicellular, No cell walls, Skeletal structure

Question 2

Answer 2

In a closed circulatory system, blood is contained in blood vessels. In an open circulatory system, blood flows around the body cavities uncontained.

Question 3

Answer 3

Endothermic animals maintain their own body temperatures through metabolic functions and body coverings. They also have involuntary mechanisms like panting, shivering, and sweating.

Question 4

How do ectothermic animals maintain their body temperature?

Answer 4

They live in habitats where conditions are fairly stable. They also use behavioral strategies.

Question 5

What kind of symmetry comes from different germ layers?

Answer 5

One germ layer: asymmetrical.
Two germ layers: radial symmetry.

Answer 6

2 atria
1 ventricle

Question 7

Three chambered septated heart

Answer 7

Similar to the three chambered heart, but oxygenated and deoxygenated blood don’t mix as much.

Question 8
