Answer:
1. Character
2. Trait
3. Monohybrid cross
4. Alleles
5. Dominant allele
6. Recessive allele
7. Phenotype
8. Genotype
Explanation:
1. Character is an inherited feature passed through genes that varies in individual e.g flower colour
2. A trait is the variant form of a character e.g red and blue flower colour are variant forms of the flower colour character.
3. Monohybrid cross is a cross between two parents differing in only one character.
4. Allele is an alternate form of a gene e.g A and a alleles for gene A
5. Dominant allele is one of the allelic pair that expresses itself by masking the expression of the other allele in a heterozygous state.
6. A recessive allele is the allele that is masked or not expressed in a gene. It is covered up by the presence of the dominant allele.
7. Phenotype is the physical and visible trait of an organism e.g Tallness, colour
8. Genotype is the genetic constituent of an organism e.g AA, Aa etc.

There are several costs associated with using wind turbines to generate electricity.
<u>Explanation:</u>
Using wind turbines to generate electricity comes with the cost of installation of the turbines. A suitable site for installation has to be selected and windmills of the required height are installed. Cost of maintenance is another cost associated with the usage of wind turbines.
The windmills are subjected to several environmental factors like rainfall, sunlight etc. These can cause damage to the windmills. Thus a regular maintenance of the turbines is essential.
Cost of procuring appropriate land for installation of wind turbines is another associated cost. Locations apt for harnessing wind energy are limited. Moreover the windmills have to be set up across a large area to produce energy in a decent scale.
