An 1815 volcanic eruption in Indonesia was followed by a three-year famine around the world. This was due to:
a.The eruption's ash and gas significantly dimmed the sun.
The volcanic ash and gases like the sulphur dioxde remained suspended in the atmosphere for years. This reduced the availability of sunlight and hindered the process of photosynthesis that the crops perform for their growth. This lead to the death of farm crops causing a global shortage of food production (famines).
e.The eruption contributed to global warming.
The volcanic gases like CO, CO2 and CH4 caused the warming up of earth in the later years. This changed the weather patterns in various parts of the planet leading to drought, floods and cyclones. Such drastic climatic changes harm the crops and lead to their shortage.
Low levels of water in the blood, causes more release of anti-diuretic hormone (ADH) into the blood. It causes increases in the retention of water in the kidneys, and thus, blood volume is increased. This may be caused by dehydration and leads to less volume of urine. It is released by the hypothalamus and stored in the posterior pituitary.
I believe the answer is C
Answer:
Explanation:
A.
The skeletal system reacted involuntarily and moved when acted upon by nerve impulse.
B.
The circulatory system worked to provide energy for the action to be completed and the respiratory system provided oxygen to the working muscle.
C.
The immune system had no immediate contribution to the action, but had been vital in preserving the body systems so thay they would be prepared to work in concert to produce the acton.
D.
The nervous system initiated the action. The nervous system transmitted the impulse need for the knee action.
E.
The doctor's nervous system and muscular systems worked together to produce the movement need to tap the patient's knee.
