Accepted Answer

Zygomycota

Question 3

Lichens are best described as:

Accepted Answer

A symbiotic relationship between a fungus and a photosynthetic organism

Question 4

Which of the following is NOT a defining feature of animal body plans?

Accepted Answer

Mode of nutrition

Question 5

During early animal development, which process results in the formation of a hollow ball of cells?

Accepted Answer

Blastulation

Question 6

Which equation correctly represents the relationship between surface area ($$A) $$and volume ($$V) $$for a spherical animal, and why is this important for gas exchange?

Accepted Answer

$$A = 4\pi r^2$ and V$$ = \frac{4}{3}\pi $$r^3$$; a higher surface area to volume ratio increases efficiency of gas exchange.
