Answer:
see in explaination
Explanation:
Density (D) is a quantity defined as mass (m) per unit volume (v): D = m ÷ v. Since these three quantities are related, you can find one of them if you know the other two. This is more helpful than it sounds because density is often a known quantity that you can look up, assuming you know the composition of the material.
Calculations are straightforward for solid objects, but things get more complicated for liquids, where density changes with temperature, and for gases, for which density is dependent on temperature and pressure.
Answer:
7 % progeny will show wild type phenotype
Explanation:
Parent 1: Normal wings and small eyes : DDee
Parent 2 : Downward wings and normal eyes : ddEE
DDee X ddEE = DdEe ( All have normal wings and normal eyes )
When a F1 individual is test crossed:
DdEe X ddee =
De/de = Parental
dE/de = Parental
DE/de = Recombinant
de/de = Recombinant
Recombination frequency between the two genes is 14% hence DE/de and de/de will each have 7% frequency. Since DE/de ( DdEe ) will give wild type phenotype, it means that 7% progeny will have wild type phenotype.
It must be nervous system...

Answer:
False
