Reason(R): Transfer RNA move out of the nucleus and after attaching on the ribosomes, form the template.

Detailed Solution for AIIMS Biology Mock Test - 10 - Question 17

tRNA is synthesized in the nucleus as a DNA template. Only 0.025% of DNA codes for tRNA. tRNA is an exception to other cellular RNAs in that a part of its ribonucleotide sequence (-CCA) is added after it comes off the DNA template tRNA is formed from only a small part of DNA molecule. Therefore, it does not show any obvious base relationship to DNA.

AIIMS Biology Mock Test - 10 - Question 18

In the following question, a statement of Assertion(A) is given followed by a corresponding statement of Reason(R).
Read the statements carefully, and mark the correct answer.
Assertion(A): Algae and fungi are classified as thallophytes.
Reason(R): They both are autotrophs.

Detailed Solution for AIIMS Biology Mock Test - 10 - Question 18

Eicher classified plant kingdom into two subdivivsions-Cryptogamae and Phanerogamae. Cryptogamae is again divided into 3 divisions thallophyta, bryophyta and pteridophyta. Thallophyta is divided into 2 classes, algae and fungi. They are called thallophyta because they have thallus likeplant body, which is not differentiated into true root, stem and leave, and they are non vascular plants. Algae are chlorophyllous and hence show autotrophic mode of nutrition i.e. they can prepare their own food. But fungi are non-chlorophyllous and cannot prepare their own food. So they are heterophic in nature.

AIIMS Biology Mock Test - 10 - Question 19

AIIMS Biology Mock Test - 10 - Question 21

In the following question, a statement of Assertion(A) is given followed by a corresponding statement of Reason(R).
Read the statements carefully, and mark the correct answer.
Assertion(A): Rhizobial aggregates have been observed at distinct sites on curled root hairs.
Reason(R): The infection thread is formed by a process of invagination of the hair cell walls in the region of curling.

Detailed Solution for AIIMS Biology Mock Test - 10 - Question 21

The accumulation of soil bacteria occurs because plant roots excrete certain growth factors into the soil. Then the bacteria either penetrate the relatively soft root hair tip or invade damaged or broken root hairs and progress in an infection thread through the cortex tissue to the immediate area of the endodermis and pericycle. Cell divisions commence in the endodermis and pericycle area and the nodule grows rapidly and pushes its way to the surface of the root.

AIIMS Biology Mock Test - 10 - Question 22

In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason(R) just below it.Read the Statement carefully and mark the correct answer-
Assertion(A): Plants mostly transpire through stomata.
Reason (R): Lenticular transpiration is found only in the woody branches.

AIIMS Biology Mock Test - 10 - Question 23

In the following question, a statement of Assertion(A) is given followed by a corresponding statement of Reason(R).
Read the statements carefully, and mark the correct answer.
Assertion(A): The final reabsorption of water from urine into blood occurs through the collecting duct of a mammalian nephron, resuliting in the production of hyperosmotic urine.
Reason(R): The loop of Henle is responsible for the formation of a sodium gradient across the depth of the cortical interstitium of a mammalian kidney.

Detailed Solution for AIIMS Biology Mock Test - 10 - Question 23

The effect of collecting duct depends on the prescence of vasopressin. This hormone increases the permeability of the collecting duct to water. Gradually the rate of reabsorption from the filterate increases and it becomes hyperosmotic.
Loop of Henle is a U-shaped tubular part which lies in the renal medulla, which has a thin walled permeable descending limb and thick walled impermeable ascending limb.Na+, K+ and Cl- are transported out of thick segement of ascending limb.
