The answer is Dichotomous Key.
A pure-breeding double-mutant (apricot, blunt) has aabb genotype, wild-type wasp has genotype AABB. If we cross them:
P: aabb x AABB
F1: all the genotypes would be AaBb
If we ten cross the F1 dihybrids with the double-mutant line:
AaBb x aabb
F2: (table)
The four phenotypes are: 1) wild-type, 2) wild type apricot-short, 3) pale orange-wild type blunt, 4) double-mutant.
The possible haploid genotypes of the gamete it received from the F1 dihybrid: AB, Ab, aB, ab. AB and ab are nonrecombinant (nonREC), like those from parents, while Ab and aB gamets are recombinant (REC) .
Answer:
a and c

I do not really have an explanation but I hope this helps :)

Answer:</h2>
Because a energy pyramid takes the shape of a pyramid.
<h2>
Explanation:</h2>
- Energy pyramids shaped the way they are this is because when an energy flow is observered in increasing order it takes a shape of a pyramid and in case for decreasing energy it take the shape of inverted pyramid.
- An energy pyramid's shape shows how the amount of useful energy that enters each level — chemical energy in the form of food — decreases as it is used by the organisms in that level. That's why energy flow is depicted in the shape of a pyramid.
Result: Pyramids is used to show a food chain.
