Answer:
Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water is transported through the roots to the rest of the plant where it's used for different purposes: Photosynthesis

Answer:
The finding that Identical twins who are reared apart tends to have the similar IQ scores will support his argument most strongly.
Explanation:
According to the researches it has been found out that the Identical twins who are reared apart tends to have the similar IQ scores.
Here,
The twins have the same heredity i.e having the same genes and the similar environment for the birth and living.
Hence,
The finding that Identical twins who are reared apart tends to have the similar IQ scores will support his argument most strongly.
Answer:
The process of dissolving is endothermic when less energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because less energy is released than is used, the molecules of the solution move more slowly, making the temperature decrease.
Explanation:
Is temperature decrease endothermic or exothermic?
Image result for A substance is dissolved in water, and the temperature of the surroundings decrease. Is this process endothermic or exothermic?
There are two methods for distinguishing between exothermic and endothermic reactions. When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases.
Answer:
Primary
Explanation:
Ecological succession is the gradual change in the structure of a community or ecosystem. There are two types namely: primary succession and secondary succession. In primary succession, the change starts with no presence of life i.e. on a barren piece of land or rock. The pioneer species are organisms that have the ability to survive on bare rocks e.g lichens.
In the image attached, the succession starts with a BARE ROCK, and the first pioneer species are lichens before gradually moving into a climax community. Hence, this is an example of primary succession. Note that, in secondary succession, there is presence of SOIL.
