Q5.

<span>The answer is A. In thermodynamics, the first law of conservation states that energy can never be destroyed or created but can only be transformed from one form to another. Therefore part of the electric energy was converted to light energy while the other dissipated as heat. However, the summation of the energy of these tow outputs in joules remains the same as initial electric energy.

Q6

<span>The answer is B. This is because the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they turn electromagnets that convert the mechanical energy into electrical energy</span>

1. In a population of 200 field mice, 98 mice are homozygous dominant for brown fur (FF), 84 mice are heterozygous (Ff), and 18
iVinArrow [24]
A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals. 
FF genotype frequency:
98÷200=0,49. There are approximately 5 <span>homozygous dominant mice in 10.
Ff genotype frequency:
84</span>÷200=0,42. There are approximately 4 <span>heterozygous mice in 10.
ff genotype frequency:
18</span>÷200=0,09. There are approximately 1 <span>homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
</span>\frac{(98*2)+84}{400}<span>=0.7
There are 7 F alleles in 10 random alleles.
f </span>allele frequency:
\frac{84+(18*2)}{400}=0.3
There are 3 f alleles in 10 random alleles.<span>
