The green house effect is when their is too much pollution in the air. Cars, factories and industries cause a lot of pollution in the air which then causes the ozone to thin out which causes it to get hotter because the ozone is a layer that keeps the temperature not too hot or cold
Answer:
51.84%
Explanation:
p² + 2pq + q² = 1 and p + q = 1
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
p = 0.72 => p² = 0.72² = 0.5184
=> Percentage of the rats are normal sized: 51.84%
Value of pi = 3.14
Radius of the semicircle = 6 cm
Diameter of the semicircle = 6 * 2 cm
= 12 cm
Perimeter of a semicircle = pi * Diameter *(1/2)
= 3.14 * 12 * 1/2
= 3.14 * 6
= 18.84 cm
From the above deduction, we can conclude that the perimeter of the semicircle in question is 18.84 cm. I hope that this is the answer that has come to your desired help.
The chemical substance in adult male pig's urine, which can also be found in other mammals, is called Puberty Accelerating Pheromone. It is also found in boar's saliva, and was said to be responsible in inducing early puberty in young female piglets.
Answer:
Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution while Artificial selection is Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
