Answer:
50%
Explanation:
According to this question involving a gene coding for seed shape in pea plant, the allele for round seeds (R) is dominant to the allele for wrinkled seeds (r). This means that a heterozygous pea plant (Rr) will have a round seed shape.
If a plant that is heterozygous for seed type (Rr) is crossed with one that has only homzygous wrinkled seeds (rr), the following gametes will be produced by each parent plant:
Rr - R and r
rr - r and r
Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:
Rr, Rr, rr and rr
Rr = round seed offsprings
rr = wrinkled seed offsprings
Since 1 out of 2 offsprings has wrinkled seeds, 1/2 × 100 = 50% is the percentage of offsprings expected to have wrinkled seeds.
<span>Protected left turns are areas for turning that are controlled by a traffic signal or traffic sign. The traffic sign may be light.</span>
A green light means you may turn left. while <span>a red light means you must stop. Opposite to this, non protected left turns are not controlled by traffic sign.

Answer:
A. The brain could not monitor the expansion and relaxation of the aorta.
Explanation:
Baroreceptors are sensors present in the aortic arch and in the carotid sinus which are responsible to sense the blood pressure and brain the communicate this information to central nervous system for maintaining the blood pressure.
When baroreceptors stopped working or uring baroreceptor dysfunction, the blood pressure increases but returns to normal after an hour. In baroreceptor dysfunction, brain will be unable to monitor the expansion and relaxation of the aorta and results in the increase blood pressure. Soon the baroreflex occurs and helps in returning the pressure toward a normal level.
Hence, the correct option is A.
