Deforestation is the removal any plant from a given area. with the absence of plant life comes the absence of photosynthesis. This causes a drop in the production of oxygen. This is the most logical conclusion.
DNA is the reason why humans live its in the eyes and can be seen out in ur too

Answer:
The correct answer will be-hypothalamus
Explanation:
A tumor is the group of abnormal cells formed due to uncontrolled division of the cells. When it is present in the brain is known as a brain tumor.
When tumor is formed in the brain, it presses the part of the brain physically and thus disrupts the functioning of that part of the brain.
In the given question, since the patient experiences the disturbing hunger and thirst which is controlled by the hypothalamus of the brain therefore the tumor would have formed in the hypothalamus.
Thus, -hypothalamus is the correct answer.
Answer:
1.An action potential is conducted deep into the muscle fiber by the T tubule.
3.The membranes of the sarcoplasmic reticulum become more permeable to calcium ions.
4.Calcium ions diffuse into the sarcoplasm around the myofibril.
2.Calcium ions bind to troponin.
5.The troponin-tropomyosin complex moves exposing active sites.
Explanation:
The arrival of a nerve impulse at synaptic end bulbs stimulates the release of acetylcholine into the synaptic cleft. The acetylcholine binds to its receptors located on the motor end-plate followed by the opening of ion channels to allow the small cations such as Na+ to enter the muscle fiber and make it positive.
The change in the membrane potential triggers the action potential that propagates along the sarcolemma into the T tubules. The action potential stimulates the release of calcium ions from the sarcoplasmic reticulum into the sarcoplasm.
The released calcium ions combine with troponin. Binding of calcium ions to troponin stimulates conformational change in troponin that makes the tropomyosin to shift away from the myosin-binding sites of actin.
The myosin heads join the free binding sites to form cross-bridges leading to contraction of muscle fiber.
