Sexual reproduction involves the fusion of two gametes – male and female gametes during fertilization to form a zygote which develops into a new organism. It involves organisms of the same species.

Sexual reproduction is the fusion or joining of male and female gametes or nuclei from different individual to form a zygote which later develops into an embryo or organism.

(i) biceps (flexor)

(ii) Triceps (extensor)

– When one touches a hot object, the sensory receptor in the skin receives the stimulus

– An impulse is transmitted from the receptor to the spinal cord, via the dorsal root/sensory neurone

– The intermediate neurone in the spinal cord passes on the impulse to the motor neurone

– The motor neurone then sends the impulses to an effector organ (muscle) via the ventral root

– All the neurones are linked by synapses across which impulses are sent

– The muscle upon receiving the impulse contracts causing the hand to be withdrawn from the hot object

(Pick Any Three)

– The semi-circular canals in the inner ear are responsible for the maintenance of balance with respect to circular motion.

– There are  three semi-circular canals and each is found in one of the geometrical planes (right angle to each other)
