b. life-cycle
c. intergenerational
d. structural
Answer:
a. intragenerational
Explanation:
Intragenerational mobility by definition: refers to a person's social movements throughout his or her lifespan. It wouldn't be structural or life cycle because those are remotely related to social mobility. Lastly it wouldn't be intergenerational because by definition is means: elating to, involving, or affecting several generations. Which is not related to social mobility at all.
B-it provides a narrow field of view and the images formed are virtual, upright,front back reversed, of same size, and at same distance
C-it provides a wider field of view and the images formed are virtual but smaller and upright
D-it provides a diminished view and the images formed are virtual, upright and bigger
Answer: Option 'C' is correct.
Explanation:
convex mirror is used to look under a vehicle during a security check because it provides a wider field of view and the images formed are virtual but smaller and upright.
As the image of convex mirror provides rear view in a small frame.
i.e. the images formed by convex mirror are virtual and as it covers wider range, the image is smaller than real but upright.
Hence, option 'C' is correct.
B. 25.5 percent
C. 72.25 percent
D. 12.75 percent
The answer is C. 72.25 percent.
The Hardy-Weinberg principle can be used:
p² + 2pq + q² = 1 and p + q = 1
where p and q are the frequencies of the alleles, and p², q² and 2pq are the frequencies of the genotypes.
The r allele (q) is found in 15% of the population:
q = 15% = 15/100
Thus, q = 0.15
To calculate the R allele frequency (p), the formula p + q = 1 is used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, p = 0.85
Knowing the frequency of the R allele (p), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225
Expressed in percentage, p² = 72.25%.
