Answer:
If a cell has salt concentration of 1 % and it is placed in the solution where the concentration of salt is 10 % so Osmosis will occurs.
Explanation:
Osmosis is a type diffusion in which molecules moves from a region of higher concentration to the region of lower concentration through a semi-permeable membrane of the cell. This membrane only allows small molecules such as ions, salts, carbondioxide and oxygen gas etc. In the solution, salt concentration is very high so the salt particles moves into the cell through semi-permeable membrane.
Answer:
They are all multi cellular

Wind dispersion of reproductive cells allowed in seedplants to colonize
land away from water supplies. If water is needed to
passively transport gametes to each other and protect them from desiccation
plants were limited to densely inhabited space near water sources.
Bryophytes & ferns (seedless) are dependent on moist environments
for reproduction but the first seed plants developed an alternate
delivery system allowing independence from water- assisted reproduction.
Conifers produce pollen that can survive by carrying water and
nutrients along. Wind can now carry these male gametophytes to female
gametophytes under the scales of a cone. Fertilization produced a
diploid seed. The seed is protected and can survive dry conditions for a
period of time before growing. Pollen and seeds transferred a conifer’s
water dependence for their reproduction to wind dependence. </span>
The correct answer is A.
I hope I've helped!
Answer:
they absorb heat from the sun
explanation: plants in the tundra tend to have dark-colored leaves and stems that help them absorb solar heat faster and keep warm for longer periods.
