C . My teacher use to say ly because you lie you're going to hell going down so c is definitely the correct answer
The right answer is A.
Osmosis is a phenomenon that considers only the exchanges between two liquid solutions of different concentrations in liquid phases separated by a semi-permeable wall. Osmosis is a phenomenon of diffusion of matter, demonstrated when solvent molecules pass through a semi-permeable membrane separating two solutions whose solute concentrations are different; the overall transfer of solvent is then from the least concentrated solution (hypotonic medium) to the most concentrated solution (hypertonic medium) to equilibrium (isotonic media).
The diffusion of matter, or chemical diffusion, refers to the natural tendency of a system to render uniform the chemical potential of each of the chemical species it contains.
Chemical diffusion is an irreversible transport phenomenon that tends to homogenize the composition of the medium.
Answer:
The correct answer will be option-C
Explanation:
Lead is a metal found in the Earth's crust which through human practices like using it in paints and other products cause lead poisoning in humans due to accumulation of lead in the body.
Lead poisoning can affect the child above 6 years and adults and prove harmful as its increased concentration can cause severe health problems common of which are the development of anaemia due to large consumption, brain damage, reduced mental growth and severe stomach ache.
Thus, Option-C is the correct answer.
Answer:
Variation can be acted on by natural selection.
Explanation:
Variation are the difference that exist in the organism in terms of the body size and can be acted upon by natural selection.
Natural selection could act on the owl body size, favor the selection of owl with small body size especially when resources available are limited and can only sustain small number of individuals leading to availability of owl with small body size in such area and a gradual reduction in the number of owl with large body size.
<h2> The average height of people in different nations has has increased approximately by 10 centimeters.</h2><h3>It mostly comes down to nutrition and child-rearing styles. </h3><h3>Some scientists believe that the increase in teenage and out-of-wedlock pregnancies in the developed world may be an unanticipated consequence of improved nutrition.</h3>
Tobacco smoking greatly increased over the last hundred or so years, but the old wives' dictum was always that "Smoking will stunt your growth!"
Hope this helped have a good day = ) .
