Answer:
I think the answer is A: Roots.
Answer: Her acceleration is -0.8 m/s²
Explanation:
The initial velocity of Sandra ( u) = 10 m/s
The final velocity of Sandra ( v) = 2 m/s
Time taken by Sandra (t) = 10 s
Let the acceleration of Sandra be 'a'
Using the equation of kinematics, we have
v = u + at
⇒ 2 = 10 + 10a
⇒ -8 = 10a
⇒ 
⇒ a = -0.8 m/s²
Hence, her acceleration is -0.8 m/s².
Answer:
It could change the DNA code resulting in failures
Explanation:
Answer: If this population were in equilibrium and if the sickle-cell allele is recessive, the proportion of the population susceptible to sickle-cell anemia under typical conditions should be 0.20
Explanation: Hardy-Weinberg law provides an equation to relate genotype frequencies and allele frequencies in a randomly mating population. The equation is;
p² + 2pq + q² = 1
For 2 alleles such as A and a, where
p² = homozygous dominant
q² = homozygous recessive and
2pq = heterozygous
From the question, it is said that the sickle-cell allele (SS) constitutes 20% (that is, 20/100) of the hemoglobin alleles in the human gene pool and it is also said to be the homozygous recessive allele.
Therefore, q² = 20/100 = 0.20
