Please help me with this east question asap What are the features of Class Demospongiae?
A. small and dull in color with a skeleton make of calcium
carbonate
B. can be up to 6 ft. in length and used as natural bath sponges
C. "glass sponges" made from silica

Please only respond if you know the answer

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

it is prolly d and c and f

b is dominant over the allele for the white fur.

a metamorphic rock would be formed.
