Please help!What are the roles of a decomposer? Check all that apply.
9966 [12]

Answer:

decomposer decomposes :) so it breaks down the organic matter into simpler compounds. it's very important process because complex compounds that build living organisms are not absorbable for other organisms, thus chemical cycling wouldn't be possible and the whole ecosystem would shut down. dead plants and animals would be everywhere and new organisms couldn't be born/grown. mold breaks down dead organic matter like dead trees. as the result simple compounds come into existence and can be assimilated by plants

In a standard monohybrid cross between purple-flowered and white-flowered peas, what fraction of the purple-flowered peas in the
Advocard [28]

Answer:

1/3

Explanation:

<em>A standard monohybrid cross is a cross that follows the dominance/recessive pattern from Mendel's experiment.</em>

It means the purple flower color is dominant over the white flower color.

Assuming the allele for purple flower color is P and that of the white flower color is p, a standard monohybrid cross will involve a true breeding PP and pp.

PP   x   pp: Pp, Pp, Pp and Pp. All the F1 offspring will have purple flowers with Pp genotype.

At F2: Pp   x   Pp = PP, Pp, Pp, and pp.

3/4 or 75% of the F2 offspring have purple flower color out of which 1 is true breeding for the trait.

Hence the fraction of the purple flowered peas in the F2 that is expected to be true-breeding (PP) is 1 out of 3.
