The anwer is attached in the form of a file read it.
Answer:
Well , I think the answer is B
This represents a closed system,and one benifit is that the risk of passing disease between other species is lower than in open system
But still I prefer you to check it out in your book
Family programmes help to reduce the rates of poverty, over population etc.
<h3><u>Explanation:</u></h3>
Family programming is a scientific approach to initiate a control over the reproduction of eligible couples in a particular population. Family plannings are initiated by the government as well as should be adopted by the couples in order to maintain a very healthy relationship as well a healthy population.
Family planning helps to reduce the poverty, hunger, epidemics, sexually transmitted diseases like AIDS etc and improves the maternal health, infant health, reduces maternal mortality rates, infant mortality rate, neonatal mortality rate etc. This uses the basic contraceptive methods as well as different other factors like when to take a baby and all.
Answer:
1. Allele frequency of b = 0.09 (or 9%)
2. Allele frequency of B = 0.91 (0.91%)
3. Genotype frequency of BB = 0.8281 (or 82.81%)
4. Genotype frequency of Bb = 0.1638 (or 16.38%)
Explanation:
Given that:
p = the frequency of the dominant allele (represented here by B) = 0.91
q = the frequency of the recessive allele (represented here by b) = 0.09
For a population in genetic equilibrium:
p + q = 1.0 (The sum of the frequencies of both alleles is 100%.)
(p + q)^2 = 1
Therefore:
p^2 + 2pq + q^2 = 1
in which:
p^2 = frequency of BB (homozygous dominant)
2pq = frequency of Bb (heterozygous)
q^2 = frequency of bb (homozygous recessive)
p^2 = 0.91^2 = 0.8281
2pq = 2(0.91)(0.9) = 0.1638
Cells because they are living things. Hope this helps! ;D
