B. Using fewer fossil fuels, such as gasoline for a car, reduces the emission of harmful pollutants into the air
Answer:
3.dominant alleles more frequent than recessive alleles
Explanation:
To achieve hard-Weinberg equilibrium, certain conditions must be made.
These conditions are:
1. There is noo mutation,
2. Existence of random mating,
3. There should be no natural selection
4. There is the infinite population size
5. No migration
Hence, in this case, the correct answer is option 3, which is not a condition to be made for Hard-Weinberg equilibrium
Answer:
The phenotypes are as follows
Purple, full- 9
Purple, constricted- 3
White, full- 3
White, constricted- 1
Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.
Explanation:
This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).
In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1
Purple color, full pod- 9
Purple color, constricted pod- 3
White flower, full pod- 3
White flower, constricted pod- 1
A sarcomere is the basic contractile unit of muscle fiber. Each sarcomere is composed of two main protein filaments—actin and myosin—which are the active structures responsible for muscular contraction. The most popular model that describes muscular contraction is called the sliding filament theory.
Answer:
correct option is a. more realistic
Explanation:
we know that marriage is legally relationship between a husband and a wife
and some for of marriage are
1 Arranged marriage
2 Civil marriage
3 Common law marriage
4 Boston marriage
5 Berdache marriage
and in second marriage
age and experience will be more
so as they age, they have gained experience from their past life
so we can say that in second marriages old couples tend to be more realistic
so correct option is a. more realistic
