Since Australia is located in the Pacific ocean, extremes of weather and climate happen throughout a season. El Niño is traditionally defined as a dry climate with reduced rainfall; in this happens to be more extreme in Australia because of its location. La Niña on the other hand is traditionally defined as a wet or cool climate with lots of rainfall; and this is indifferent as La Niña in Australia tend to be more extreme too.
A) platelets aggregate at the wound site, and the fibrin mesh forms
Although the blood vessels do constrict, that's during homeostasis
Answer:
40x, 100x, and 400x
Explanation:
The ocular lens (closest to your eye) usually has a 10x power.
The objective lenses (closest to the object) usually have powers of 4x, 10x, and 40x.
Combined, they give magnifications of 40x, 100x, and 400x.
Complete question:
A sample of butterflies contained 50% yellow-winged individuals and 50% black-winged individuals. In this species, wing color is determined by a single gene with two alleles, and the allele for black is dominant. Which of the following statements about the allele frequencies in the sample would most likely be true? Do not assume that this sample was obtained from a population in genetic equilibrium.
a)The frequency of the yellow allele is greater than that of the black allele.
b)The allele frequency of yellow is 3 times the allele frequency of black.
c)The allele frequency of yellow is twice the allele frequency of black.
d)The allele frequencies of black and yellow are equal.
e) The allele frequency of black is greater than the allele frequency of yellow.
2.Now assume that the population of butterflies sampled in question above is in Hardy-Weinberg equilibrium. Also assume that the sample is random and large enough that the allele frequencies in the sample equal the allele frequencies in the population. What is the frequency of the allele for a) yellow wings in the population? Assuming Hardy-Weinberg equilibrium in question 1, what would the correct answer be and why?
Answer:
- a)The frequency of the yellow allele is greater than that of the black allele.
- f(b) = q = 0.71
