When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal length.
<h2>Frequency of allele </h2>
Explanation:
Hardy Weinberg Equilibrium is used to calculate the allelic as well as genotypic frequency
Allelic frequency of dominant and recessive allele is represented by p and q respectively whereas genotypic frequency of dominant genotype is represented by 
and 
respectively
Given:
H allele (p) = hairy heffalump (dominant)
h allele (q) = hairless heffalump (recessive)
36% of heffalump population is hairless represents the % of recessive genotype, hh () =36%
Calculation of frequency of the h allele (q) :
Frequency of genotype hh () will be: 36/100=0.36 or 0.6*0.6
Frequency of h allele (q) will be 0.6
<span>Nervous System - Nucleus - control (responding to certain neurotransmitters by allowing transcription factors to be formed)
Respiratory System - Plasma Membrane (alveoli allow certain particles into the cells but want to keep contaminants out)
Reproductive System - Nucleus - DNA (determines in part the genome and developmental process of the offspring)
Digestive System - Mitochondria (want full redox reaction to occur in the organelle based on nutrients extracted from food)
Integumentary System - Cytoskeleton (for support as well as in the construction of the basal lamina)
Musculoskeletal System - Endomembrane System (think about the sarcoplasmic reticulum and the effect of increased surface area when calcium is released)
Circulatory System - Passive Transport (through capillaries especially)</span>
This would be because the grass that they eat are in the area that the zebra population is booming in.
