Answer: The diagram attached is known as the nephron,it is labelled from A to E, the structure labelled E which is known as the COLLECTING DUCT can be influenced by hormones to change the concentration of urine.
Explanation: Antidiuretic hormone ADH is one of the hormones that is produced by the anterior lobe of the pituitary gland of the endocrine system,this antidiuretic hormone performs certain functions of which one is that it helps to increase the rate and amount of water that is reabasorbed in the distal convulated tubule of the nephron during the second stage of urine formation,when these water are reabsorbed,the urine being produced becomes more concentrated and there is a further reduction in the volume/quantity of urine produced.
When this volume of urine is decreased/reduced, plasma osmolarity increases in reaction to the decreased volume of urine.
Urine are also reabsorbed in the collecting duct.

Explanation:
Medulla oblongata controls consciousness and arousal (the reticular formation) and its three vital reflex centers control the blood vessels diameter, heartbeat and breathing rate (the involuntary actions). This makes option D correct. The lower part of brain stem forms the hind brain which comprises of medulla oblongata, pons and cerebellum. This makes option C incorrect as medulla is not part of forebrain. Cerebellum is the convoluted subdivision of brain stem and is associated with coordination of muscular movement, muscle tone and balance i.e. the voluntary actions. Option B is incorrect. Spinal cord, along with brain, forms central nervous system which serves to integrate the sensory inputs from internal and external environment as received by sensory neurons and process and finally transmit the nerve impulses to effectors (muscles and glands). This makes option A incorrect.
Answer:
True
Explanation:
Mental demands may be psychological or emotional and could lead to stress if not properly managed.
When stress takes its toll, it limits the individual's ability to perform efficiently on the job even with respect to tasks that are routinely carried out.
With the invent of technology, computers and other mobile devices may be used to reduce the need for memorization, as this involves a lot of mental energy.
