Answer:
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.
A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.
An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.
In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.
A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.
A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.

1. No, cows don't get energy from sunlight.
2. 2 living parts are flowers and trees and 2 non-living parts are fences & houses
3. No, flies don't develop from garbage.
4. The populations in that living space will decline, because there won't be enough space.
5. A polar bear lives in a cold,arctic habitat.
6. A niche is the match of a species to a specific environmental condition.
Explanation:
DNA is the main type of genetic material found in a cell. In addition,
it is found in the nucleus of the cell, so (D) is correct. DNA in the
nucleus is used in replication (through mitosis and meiosis) via
daughter cells to continue cell growth.

Answer:
Principles by Mendel
Explanation:
The heritage principles of Gregor Mendel are at the core of modern genetic engineering. Mendel has created three heritage principles by conducting experiments with pea plant breeding, which described the passing on of genetic characteristics before anyone thought that genes did exist.Mendel referred to this components as "elementen" and suggested that, throughout sexual reproduction, each parent contributes a form of elementary elementen to the resultant offspring. This blend of parental elementen then defined what type of characteristic was noticeable in the descendants.
Genetic concepts are laws or guidelines regulating the biological heredity process, the transition of parents' to children's attributes by information that is biochemically transmitted by DNA, to gene units.
