Answer: The presence of small amounts of heat-trapping greenhouse gases in the atmosphere warms Earth's surface, resulting in a planet that sustains liquid water and life. Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species. Changes in Earth's system affects the growth of life on Earth. ... Life on Earth includes all the living things such as plants animals humans microbes etc. All take part in different cycles such as carbon cycle and nitrogen cycle and can influence global climate by changing chemical composition of atmosphere.
Explanation:
If a rodent eats grasshoppers and if the falcon eats the rodent. The rodent food supply is being diminished so the rodent's population also diminishes, so the falcon as diminishes as well.
Novice, apprentice, master, mentor. Student examples will vary, but should follow the model.
Example : Driving a car
S1 - take a class, have someone teach you about the parts of a car, traffic laws etc.
S2 - practice driving with parent/teacher - learners permit
S3 - drive on own, accident free, follow all traffic laws - No tickets or accidents
S4 - teach someone else how to drive
Answer:
The frequency of the Y allele is 0.7
The frequency of the y allele is 0.3
The frequency of the YY homozygote is 0.49
The frequency of the Yy heterozygote is 0.42
Explanation:
According to Hardy-Weinberg Equilibrium,
p + q = 1
p² + 2pq + q² = 1
where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of dominant homozygous genotype
2pq = frequency of heterozygous genotype
q² = frequency of recessive homozygous genotype
Here,
yy = q² = 0.09
frequency of y allele = q = √0.09 = 0.3
frequency of Y allele = p = 1-q = 1-0.3 = 0.7
p² = YY = (0.7)² = 0.49
2pq = Yy = 2 * 0.7 * 0.3 = 0.42
