Multiple Choice Questions

Given below is a table comparing the effects of sympathetic and parasympathetic nervous system
for four feature (a-d). Which one feature is correctly described

Feature Sympathetic nervous system Parasympathetic nervous system

a) Salivary glands Stimulate Secretion Inhibit Secretion
b) Pupil of the eye Dilate Constricts
c) Heart rate Decreases Increases
d) Intestinal peristalsis Stimulates Inhibits

Which one of the following animals is correctly matched with its one characteristic and the taxon

Animal Characteristic Taxon

Millipede Ventral nerve cord Arachnida
Duckbill platypus Oviparous Mammalia
Silverfish Pectoral and pelvic fin Chordata
Sea anemone Triploblastic Cnidaria

All mammals without any exception are characterised by

viviparity and biconcave red blood cells
extra-abdominal testes and a four chambered heart
heterodont teeth and 12 pairs of cranial nerves
a muscular diaphragm and milk producing
glands.

Which one of the following pairs of the kind of cells and their secretion is correctly matched

Oxyntic cells a secretion with pH between 2.0 and 3.0
Alpha cells of islets of Langerhans secretion that decreases blood sugar level
Kupffer cells a digestive enzyme that hydrolyses nucleic acids
Sebaceous glands a secretion that evaporates for cooling

Examine the diagram of the two cell types A and B given below and select the correct option
A B

Cell A is the rod cell found evenly all over retina

Cell A is the cone cell more concentrated in the fovea central is

Cell B is concerned with colour vision in bright light

Cell A is sensitive to low light intensities

Cell A is the rod cell found evenly all over retina

The retina contains two types of photoreceptors, rods and cones. The rods are more numerous, some 120 million, and are more sensitive than the cones. However, they are not sensitive to color. The 6 to 7 million cones provide the eye's color sensitivity and they are much more concentrated in the central yellow spot known as the macula. In the center of that region is the " fovea centralis", a 0.3 mm diameter rod-free area with very thin, densely packed cones.

Sternum, femur, tibia, fibula
Tarsals, femur, metatarsals, tibia
