A man who heavily smokes has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, ma
nexus9112 [7]

Answer:

If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children

Explanation:

Even tho the cause of lung cancer is not very clear, a genetic predisposition is of a great influence, his smoking and therefore causing a lung cancer is not appliable to his children because of no connection, but in the sense of having a mutation which makes you predisposable to the cancer with or without the smoking, can lead to a high risk of gene inheritance and therefore inheriting the mutation with a high risk of getting lung cancer excluding the smoking.

red blood cells are placed in water that has been distilled so there are no solutes dissolved in the water. Are the red blood ce
makvit [3.9K]
Red blood cells will swell and burst. The reason behind this is that red blood cells are okay when they are in the plasma (the watery part of the blood) because the solutes in plasma are so  well balanced that plasma is rendered isotonic. An isotonic solution is a type of solution that has the same salt concentration as its surrounding environment and thus the substances around it e.g. cells neither gain nor lose water. In the blood plasma, the red blood cells neither lose nor gain water  and so they remain intact.<span>However distilled water is hypotonic (has less or no solutes) and therefore osmosis will take place when red blood cell which have a higher solute concentration are placed in it. Water molecules will leave the distilled water and pass into the red blood cells through the semi-permeable membrane of the cells in an attempt to equalize the difference in osmotic pressure on either side of the membrane. In so doing, water will accumulate in the cell which will then swell to capacity and ultimately burst.</span>
