Answer:
<h2>(2) Thermoluminescent dosimeter</h2>
Explanation:
Entrance Skin Dose (ESD) is the measurement of radiation dose absorbed by the patient . ESD directly estimates the quantity of radiation dose of the patient by using the Thermoluminescent dosimeter. It is also known as the entrance surface dose. Body habitus contributes to an increase in the dose of Entrance Skin Dose (ESD). The estimated quantity radiation dose measured by the Thermoluminescent dosimeter can be calculated by Monte Carlo simulations upon several examinations of X-ray.
Answer:
elongation rate of strain of S.cerevisiae during transcription.
wild-type and experimental strain not treated with soultion of amanitin will be the control group. The elongation rate of mRNA of this group must be observed.
Explanation:
Dependent variable is one whose value depends on another value. Here effect of presence of mRNA polymerase enzyme and inhibtor on elnogatino rate of mRNA is being observed. So elongation rate is the dependent variable
Control group is one where independent variable whose effect is being observed can't influence the results. In experiment 2, the effect of inhibitor is being observed. So the control group must not have that inhibitor. Other conditions must remain same for experimentan and control group.
The answer ito the question is B
Explanation:
In the given question,
suppose allele A and a determines the color of the fruit whereas allele B and b determines the shape of the fruit.
The genotype for white, disc shape fruits is- AABB
the genotype for yellow, long fruits is- aabb
F1 progeny will be- AABB x aabb
AaBb
F2 cross- AaBb x AaBb
AB Ab aB ab
AB <em>AABB AABb AaBB AaBb</em>
Ab <em>AABb AAbb AaBb Aabb</em>
aB <em> AaBB AaBb aaBB aaBb</em>
ab <em>AaBb Aabb aaBb aabb</em>
The genotype of F2 cross are-
1. 9/16 A- B- disc-shaped (like F1)
2. 3/16 A- bb spherical
3. 3/16 aa B- spherical
4. 1/16 aa bb long.
