The right answer is: neutral mutation.
Neutral mutation is a nucleotide change in the DNA of the leading to the replacement of one amino acid by another amino acid possessing the same physicochemical properties.
example: AAA to AGA (Lysine to Arginine).
both these two amino acids are positively charged, so the charge of the protein will not change
Answer: genetics, gregor mendel, they had easily observable traits, A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits to its offspring of many generations., He removed the anthers from the flowers of some of the plants in his experiments. a distinguishing quality or characteristic,
Explanation:
Answer:
- The solution is hyperosmotic to the body.
- What is the concentration of nonpenetrating solutes (NP) in the solution? 500 mosmol/L
- What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.) 300 mosmol/L
- When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same? increased
- Based on your answer regarding water movement, the solution was hypotonic to the body's cells.
Explanation:
A hyperosmotic (or hypertonic) solution is a solution with a greater solute concentration. If a cell is placed in a hyperosmotic solution the water will leave the cell and the cell will shrink. Conversely, a hypotonic solution is a solution that has a lower concentration of solute. If a cell is placed in a hypotonic solution the water will enter the cell through osmosis and the cell increases in size. In this case, the NaCl is a non-penetrating solute, and thereby the concentration in the body's cells maintains constant. Moreover, urea is a penetrating solute, thereby it will penetrate in the cells until the equilibrium is reached (i.e., the cells will increase in volume).
Answer:
1) the plasma membrane of cells
Explanation:
Phospholipids are made of a phosphate group and fatty acid chain. The phosphate group is hydrophilic (attracted to water), while the fatty acid group is hydrophobic (repelled by water). This is important to the membrane because it allows for the cell to interact with the water inside and outside the cell. Therefore, the answer is number 1.
Quantitative measurements are those that deal with a quantity, for example:
Mass of as sample
Length of a piece of wire
Molecules in a mole
Volume of a gas
Temperature of a sample
These types of measurements are called Extensive.
Qualitative measurements are those that deal with the quality, for example:
Color of a sample
Texture of a surface
Coarseness of a powder
Aroma of a reaction
Malleability of a metal
These types of measurements are called Intensive.
