Illnesses and conditions caused by factors in the environment are collectively called environmental diseases. Pesticides, chemicals, radiation, air pollution, and water pollution, are some of the manmade hazards that are believed to contribute to human illnesses.
Answer:
Competition on the same receptor binding site
Explanation:
Adenosine is a neuromodulator or chemical in nervous system that makes humans feel tired while caffeine act as adenosine antagonist of adenosine blocker that makes human feel fresh.
Adenosine and caffeine both binds to the same receptor and compete for the same binding site. When adenosine binds to its receptors, the neural activity slows down but when caffeine binds to the same receptor, it do not allow adenosine to bind the same receptor and do not slows down the neural activity.
Hence, the correct answer is "Competition on the same receptor binding site".
Answer: Emotional stability
Explanation:
Emotional stability can be defined as the ability of the person to be stable in any of the conditions emotionally. The person if emotionally stable can adjust in any of the conditions.
Out of Big five traits emotional stability is one of the most strongly related fact which is required at any stage of life.
The people with high emotional stability ensure more positive character and stay happy even in the worse conditions.
Answer:Some common synonyms of busy are assiduous, diligent, industrious, and sedulous. While all these words mean "actively engaged or occupied," busy chiefly stresses activity as opposed to idleness or leisure.
<u>Microglia cells </u>are glial cells that respond to injury or disease by multiplying, and then engulfing cellular debris or even entire cells.
<h3>Functions of microglia</h3>
Microglia cells are the immune cells of the central nervous system and consequently play important roles in brain infections and inflammation. Recent in vivo imaging studies have revealed that in the resting healthy brain, microglia are highly dynamic, moving constantly to actively survey the brain parenchyma.
These active microglia can rapidly respond to pathological insults, becoming activated to induce a range of effects that may contribute to both pathogenesis, or to confer neuronal protection.
However, interactions between microglia and neurons are being recognized as important in shaping neural circuit activity under more normal, physiological conditions. During development and neurogenesis, microglia interactions with neurons help to shape the final patterns of neural circuits important for behaviour and with implications for diseases.
