In year 1, suppose a new predator that could not differentiate between the light green and dark-green lizards was introduced on the west side of the stream. this was the only predator of lizards on this side of the stream. how would the introduction of this predator affect the population ratio of dark green to light-green lizards? a. the proportion of light-green lizards would increase drastically in the following year. b. the ratio would gradually increase every year. c. the ratio would not show any changes in the following year. d. the proportion of dark-green

C. The ratio would not show any changes in the following year.

Explanation:

Since the introduced (and only) predator can not differentiate between the tone of the lizards (dark and light), you can assume it will feed from them in an equal proportion, so the ratio between dark green and light green lizards will not be affected.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

the electromagnetic energy from the sun arrives in the form of visible and invisible light.
