| # | Question | Ans |
|---|---|---|
| 21. |
In mammalian males, the excretory and reproductive systems share the A. Ureter B. vas deferens C. Urethra D. Testes |
C |
| 22. |
Metabolic production of urea is carried out in the A. urinary bladder and kidney B. Liver C. Pancreas D. Kidney and malphigian tubule Detailed SolutionAll the metabolic wastes are excreted in a form of water solutes through the excretory organs (nephridia, Malpighian tubules, kidneys), with the exception of CO2, which is excreted together with the water vapor throughout the lungs. The elimination of these compounds enables the chemical homeostasis of the organism. Urea is produced in the liver and is a metabolite |

 The structure can be found in the A. Sympathetic and parasympathetic nervous systems B. Peripheral and central nervous system C. Peripheral nervous system only D. Central nervous system only |
B |
| 24. |
 The point marked I is referred to as A. myelin sheath B. dendrites C. axon D. node of Ranvier |
D |
| 25. |
Homologous pairs of chromosome separate during A. Cytolysis B. Cleavage C. Mitosis D. Meiosis |
D |
| 26. |
An example of a caryopsis is A. Guava B. Maize grain C. Coconut D. Tomato |
B |
| 27. |
The response of plants to external stimuli in a non-directional manner is known as A. Tactic movement B. Phototropism C. Geotropism D. Nastic movement Detailed SolutionPlant movements that are independent of the direction of the stimulus or that are caused by non-directional stimuli are called nastic movements or nasties |
|
| 28. |
The most important hormone that induces the ripening of fruit is A. Ethylene B. Indole acetic acid C. Gibberallin D. Cytokinin |
A |
| 29. |
