Answer:
Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO
2
and H+ concentration and send necessary signals to the rhythm centre for remedial actions. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
Explanation:
In biopsychology, there is a system in the brain which is called the limbic system. The limbic system is responsible for one's memory, emotions and instincts -drives.
Many researchers suggest that the existence of emotions helped the animal kingdom to respond to sociality and survive better, emotion can also be translated into care and love. These traits also aid why infants, babies and other offsprings of animals are cared for which has a great influence on the survival of the species.
Amygdala, responsible for pain, aggression and grief which is anterior to the hippocampus factors why our memories have incorporated and is strengthened with emotions at that specific circumstance.

(A) a red brick reflects red light and absorbs blue and green light
Answer:
The most correct statement is d. Ganglia associated with afferent nerve fibers contain cell bodies of sensory neurons.
Explanation:
Ganglia are considered a group of nerve cell bodies and are responsible for carrying nerve impulses. The sensory nerve ganglion collects and modulates the sensory information, and constitutes the deposits of the neuronal somas of the primary afferent fibers of the sensory system. This consists of afferent nerve cell bodies, efferent nerve cell bodies, and neuronal axons. It acts by receiving signals from the periphery and sending them to the brain, that is, it has an afferent function. Afferent fibers transmit sensory stimuli from the skin, mucous membranes and deep structures, for this, ganglia are constituted by abundant distinctive neuronal connections, which are responsible for receiving these signals and fulfilling their afferent function.
