The answer is : b. Theoretically, noise pollution could be so great that it could kill a person. Noise pollution affect our sense of hearing... leading to hearing loss. It also disturb our sleep which could lead to fatigue. Long-term noise above a certain level can have a harmful influence on our health. Research shows that road traffic and aircraft noise increase the risk of high blood pressure. Noise pollution also affects wildlife, where animals depend wholly on their hearing for hunting.
Answer:
B because the diffusion gradient is steeper there
Explanation:
Oxygen moves in the cell through the process of diffusion which means it moves from its higher concentration towards its lower concentration. More the difference in concentration, concentration gradient will be more steeper and diffusion will take faster.
So in this case cell, B cell consumes oxygen at a faster rate because it is more metabolically active therefore as oxygen is consumed at a faster rate the concentration difference in B cell becomes high and the diffusion gradient becomes steeper so oxygen will diffuse more quickly in cell B.
Glycosylation is the reaction in which a carbohydrate, i.e. a glycosyl donor, is attached to a hydroxyl or other functional group of another molecule in order to form a glycoconjugate. In biology, glycosylation usually refers to an enzyme-catalysed reaction, whereas glycation may refer to a non-enzymatic reaction.
The answer should be 4) as it is known that uv radiation might have an effect on dna, thus causing mutations such as skin cancer in humans.
