Explanation: Factors Affecting the Rate of Osmosis
Temperature - The higher the temperature, the faster the movement of water molecules across the semi permeable membrane.
Osmosis is the passage of water from a low solute concentration area through a semi-permeable membrane to a high solute concentration area to equalize the solute concentrations on both sides. Meaning of the terms: solute, solvent and solution. A solvent is the base substance, where a solute is being dissolved and the result is the solution. Through osmosis, water is provided to the cells of your body; it plays a significant role in the preservation of life. It is this process that helps plants receive water and is even used in kidney dialysis.
The middle stone age and the later stone age corresponds to the middle and the late pleistocene.
Cultural evolution during the middle and the late pleistocene :-
In southwestern Asia as well as northern and southern Africa, personal ornaments in the form of perforated seashells are recorded from the early Late Pleistocene. In the Old World, Neanderthals and anatomically modern humans are linked to a range of personal ornamentation by about 40,000 years ago (Ka). These include fully created ornaments as well as organically modified things. The appearance of figurative art, mythical imagery, and other types of items, like as musical instruments, at various times in history suggest that completely modern behavior began to emerge more gradually towards the middle of the Late Pleistocene and most definitely no later than 40 Ka. Many, but not all, of the lengthy and rigorous history of study might well have helped to the relevant data come from Europe.

Answer: Point mutation is easily reversible, thus non-lethal
Explanation:
Point mutation is caused by exchange of a single nucleotide for another. These change is called
1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)
2) Transversion (when a purine base substitute a pyrimidine base).
However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate
