In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present.
Answer: Water will leave the cell and the cell will shrink.
Explanation:
Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. <u>However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment.</u> The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:
- <u>Hypotonic</u>: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell.
- <u>Hypertonic</u>: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell.
- <u>Isotonic</u>: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.
If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.
Answer:
Air is essential for almost all organisms.
Explanation:
Missense Mutation. A nucleotide was substituted for another- and most importantly- changes the final amino acid.
Poor blood circulation will likely reduce the contraction power of a person's myosin.
<span>Myosins are motor proteins and they play a major role in muscle contraction and in a wide range of other motility processes in eukaryotes.
They depend on the ATP and are also responsible for actin-based motility.
</span>They are also used to produce <span>mechanical energy that is </span>used in various body<span> functions such as muscle movement and contraction.</span>
