The increase in size of the heart enables the left ventricle to stretch more and thus fill with more blood. The increase in muscle wall thickness also increases the contractility resulting in increased stroke volume at rest and during exercise, increasing blood supply to the body.

laiz [17]
The human eye has three types of cone cells. These cones respond to the light and its varying signals wavelengths determines how the brain will perceive the lights signals and determine the colors the person sees. 

Damage to any one of the types of cone cells doesn't cause total blindness because they have independent structure and are parallel to each other. Instead, damage to any one of the types of cone may cause COLOR BLINDNESS.

I had a room full of 666 cockroaches which included 24 albinos. These albinos were so scary looking that I squashed them with a
Aleks04 [339]

Answer:

Number of albino cockroaches = 486 cockroaches

Explanation:

Assuming that the population is in Hardy-Weinberg equilibrium and that albinism is recessive, the Hardy-Weinberg equation is used to determine the frequencies ofnthe different alleles in the population

According to the Hardy-Weinberg equation : p² + 2pq + q² = 1

Also p + q = 1

Where p² is the frequency of cockroaches having similar alleles for the dominant trait;

2pq is the frequency of individuals with the heterozygous allele, while q² is the frequency of the individuals having similar allele the recessive trait, albinism.

q² = 24/666

q² = 0.036

Since, the frequency of albinism in the population 0.036, number of individuals with the recessive allele, that is albino cockroaches in the next generation is obtained by multiplying the frequency with the number of individuals in the next generation.

Number of albino cockroaches = 0.036 × 13485

Number of albino cockroaches = 486 cockroaches
