Answer:
green house effect is trapping of heat.
Answer:
C. Hypothesis
Explanation:
Hypothesis is a proposed explanation for a certain occurrence and when the explanation is conclusive, then it becomes a theory.
The frequency of allele is illustrated as the ratio of that specific allele in the population. As one knows that as the humans are diploid, so the total number of alleles is double of the total number of people in the population.
In order to determne the allele frequencies for A and B, there is a need to know that the persons with type A blood are homozygous AA, the persons with type AB blood are heterozygous AB, and the persons with type B blood are homozygous BB.
The frequency of A is:
2*(number of AA) + (number of AB) divided by 2 * (total number of individuals)
Therefore,
{2 * (200) + (75)} / 2 (200 +75 +25)
This comes out to be 475/600 = 0.792. Thus, p = 0.792.
Since, q is 1 - p
Then, q = 1 - 0.792 i.e 0.208.
A wetland refers to a different ecosystem, which is flooded by water, either seasonally or permanently, where the oxygen-free procedures exist. The main element, which separates wetlands from the other water bodies or landforms is the characteristic vegetation of aquatic plants, amended with the specific hydric soil.
Swamp refers to a wetland ecosystem featured by mineral soils with poor drainage and by plant species dominated by trees. The swamps are found all through the world, most usually in low-lying regions with poor drainage adjacent to rivers that supply the swamp with water. Some of the swamps develop from marshes, which gradually fill in, permitting woody shrubs and trees to develop.
