To determine the aqueous layer-<span>The NaHCO3 solution is an aqueous solution (water is the solvent). Water is more dense than ether and sinks to the bottom, while the ether sits on top. Most organic solvents will be less dense than water, unless you're working with halogenated solvents like methylene chloride, chloroform, or carbon tetrachloride.</span>
Many cacti have roots that spread out widely, but only penetrate a short distance into the soil. In one case, a young saguaro only 12 cm (4.7 in) tall had a root system with a diameter of 2 m (7 ft), but no more than 10 cm (4 in) deep.
In other words they can't penetrate that deep.
Answer:
A) 
%
B) 
%
Explanation:
A) Given
Frequency of individuals in the population having recessive phenotypes 
%
Frequency of individuals in the population having recessive phenotypes is represented by 
Thus frequency of recessive genes is equal to 
frequency of dominant genes is equal to
Now,
% of genes exist in the heterozygous condition
B.
Frequency of individuals in the population having recessive phenotypes 
%
Frequency of individuals in the population having recessive phenotypes is represented by
Thus frequency of recessive genes is equal to 
frequency of dominant genes is equal to
Now,
% of genes exist in the heterozygous condition
Answer:
The correct answer is "yes it satisfies the definition of the scientific law"
Explanation:
The scientific theory states the verified explanation of the natural world. This things or the experiments can be determined by repeatedly testing by the given scientific methods. The cell theory also meets the definition of the very known scientific theory as it has also helped in determining it by various experiments as well as the observations. The cell can be studied under the microscope by the basic staining procedures that has already been mentioned in the theory.
Answer:
A hypertonic environment will result in cell shrinkage due to osmosis. However, this question is unclear because it's not the lack of water that causes shrinkage, it's the loss of cell water due to there being more concentrated aqueous particles outside of the cell vs. inside of the cell. I would still go with hypertonic though.
