The answer is C DNA and that is the answer
Microscopes are one of the laboratory tools used to maximize the visual acuity of a certain specimen, it maybe a living or non-living organism or object. Thus, microscopes are widely used in these laboratories to increase microscopic observation with entities that cannot be perceived thru the naked eye. However, for scientisits to determine such specimen is a living thing if there's a presence of cell. Cell cannot be viewed via the visual organs alone but with the microscope a living specimen can be discerned with its characteristics such as cellular structure, slight and fidgety movement and other particular details..
The correct answer is natural selection. C is the answer!
Bacteria has a stronger resistance that usually produces even more resistant bacteria, and the cycle just repeats itself, making more and more resistant bacteria. This process is called Natural Selection.
Hope that helped!

The diastolic pressure refers the two values are recorded during the measurement of blood pressure.It is the number or the bottom number indicates the pressure in the arteries when the heart rests between beats.
Less then 80 are the normal diastolic blood pressure. Prehypertension which is indicaated by the blood pressure between 80 to 90. The first, systolic pressure, which represents the peak arterial pressure during systole. The second, that represent minimum arterial pressure during diastole.
the force the heart exerts on the walls of the arteries in between beats can be easily measured by the diastolic blood pressure .Diastolic blood pressure is mainly determined by the total arterial peripheral resistance which majorly influence Arterial elastance and compliance.

Answer:A) The ocean is hypertonic to the erythrocytes.
Explanation:cells shrink when placed in an hypertonic solution.
This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.
The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
