Answer:
1/4
Explanation:
Let the earlobe allele be represented by A. since the attached earlobe is the recessive trait, the genotype would be aa while the free earlobe would be AA. The heterozygous condition would be Aa.
Two individuals heterozygous for free earlobes mated:
Aa x Aa
AA Aa Aa aa
AA and Aa = Free earlobe = 3/4
aa = attached earlobe = 1/4
<em>Hence, the probability of the couple having a child with an attached earlobe is </em><em>1/4.</em>

The patient may have imbalance of the Thyroxine hormone, which is produced by the thyroid glands. It is known to have a significant effect of basal metabolic rates, as they stimulate the metabolic functions of tissues all over the body. An excess of thyroxine may cause BMR to spike up. This is most commonly seen in women after they have reached menopause. Women nearing menopause may also experience increased basal metabolic rate.
Answer:
Option (1).
Explanation:
Dual x-ray absorptiometry technique is used for the evaluation of the bone mineral density. The bone densitometry is normally used in this technique to estimate the mineral content of bone.
The radiation dose in the absorptiometry is considerable and only small or low amount of radiation dose is considered. The heavy dose may cause health problems in the individual. The photon energies are used for the bone and soft tissue. The treatment of osteoporesis can be done by this technique.
Thus, the correct answer is option (1).
