1) Long loop of Henle so that reabsorption of water can takes place to a great extent.
2) Small glomeruli so as to reduce rate of ultrafiltration.
Answer:
Ventlation or breathing, is the movement of air through the conducting passage between the atmosphere and the the lungs. The air moves through passeng because of pressure gradients that are produced by contraction of the diaphragm and thoracic muscles.
Answer:
Option a
Explanation:
The front of the white paper packet of the OSL dosimeters may be color-coded to facilitate correct usage and placement of the badge on the body of occupationally exposed personnel.
OSL dosimeters are recently developed and are of high quality than thermoluminescent dosimeters. It is used to monitor patients health status. Furthermore, it is very sensitive to any change or drop in reading. it give accurate readings even at 1 mrem for both gamma ray photos and X-rays.

Answer:
Gene knockout is a technique used to determine the function of a gene that has already been sequenced, which is achieved by analyzing the phenotype of the individual carrying the knockout mutation(s). Moreover, gene sequencing is a technique used to determine the sequence of a given gene, which allows to determine how gene variants (polymorphisms) may be associated with the phenotypes of the target trait.
Explanation:
In genetics, gene knockout is a technique used to trigger mutations in a (already) sequenced gene in order to inactive its function and observe the resulting phenotype for a particular trait. This approach that starts with the inactivation of a given gene and ends with the phenotype is known as reverse-genetics. On the other hand, gene sequencing can be defined as the methodologies/techniques/tools used to determine the nucleotide base pair sequence of a particular gene. The gene knockout technique involves knowing a priori the gene sequence in order to obtain a gene knockout (gene KO). The combination of the information obtained from these techniques can be used to determine how variation (genetic variation) affects the expression of a phenotypic trait.
