Answer:
Frequency of allele A1- 0.41
Explanation:
In Hardy weinberg equilibrium,
P refers to the dominant allele
q refers to the recessive allele
The allele frequency will be p+q=1
The genotypic frequency is- P²+q²+2pq=1
P²= genotype of dominant trait ( A1A1)- 77
2pq= genotype of heterozygotes (2pq)- 65
q²= genotype of recessive trait (A2A2)- 123
Total number of offsprings= 77+ 65+ 123
= 265
Now to calculate allele frequency of A1=
= 77/265 + 1/2( 65//265)
= 0.290+ 0.122
= 0.413
Thus, 0.41 is correct.
Answer:
Gills allow for gas exchange
Explanation:
C bc the key word is replaced
From the following items:
1. An atmosphere containing oxygen
2. wooden furniture
3.food, including vegetables, fruits, and meats
4.fibers to make cloth
5. drugs such as aspirin
6. fossil fuels such as oil, gas, coal and nutrient-rich soil
ALL of these things are one way or another, exist because of green plans. E.g. Oxygen is released by plans, while wood for furniture comes from trees.
All fruits and vegetables are grown on plans while even meat comes from animals who eat green plans.
Fibres such as wool also come from animals which eat plans, and fossil fuel is made from the remains from millions of years of old plans in the ground.
