2. DNA is important to carry genes or genetic materials of the parents
Answer:
Option C
Explanation:
Given ,
A1 allele is carried by 
% people
Let us assume A1 s dominant genotype
This means 
Thus, frequency of allele in the given population is 
It is also given that the population is in Hardy-Weinberg equilibrium thus
Frequency of fruit fly with genotype A2A2 will be
As per Hardy-Weinberg's second equation of equilibrium
Hence, option C is correct
Answer:
apply direct pressure to the injury site while manually stabilizing the stick in her arm
Explanation:
Spinal immobilization can generally be explained as the use of adjuncts such as cervical collar, that are being applied to minimize movement of the spinal column.
In this case, since the area where the girl is injured is the forearm, it has no direct connection with the spinal column, this means that, the cervical spinal immobilization is unnecessary.
Therefore, there should be direct application of pressure to the injury site while manually stabilizing the stick in her arm.
