Answer:
Osmosis is the flow of a solvent into a solution through a semipermeable membrane. Osmotic pressure is the pressure that stops the process of osmosis. Osmotic pressure is a colligative property of a substance since it depends on the concentration of the solute and not its chemical nature.
What are some ways that your body may need to create new cells?
Answer:
Proteins give your body amino acids — the building blocks that help your body's cells do all of their everyday activities. Proteins help your body build new cells, repair old cells, create hormones and enzymes, and keep your immune system healthy.
The diagram below shows the relative concentration of molecules inside and outside of a cell. Which statement best describes the general direction of diffusion across the membrane of this cell?
(1) Glucose would diffuse into the cell.
(2) Protein would diffuse out of the cell.
(3) Carbon dioxide would diffuse out of the cell.
(4) Oxygen would diffuse into the cell.
HELP PLEASE
Carbon dioxide will diffuse out of the cell in the given picture. Option C is correct.
Diffusion:
It is the phenomenon in which a substance moves from its higher concentration to its low solute concentration.
Here,
The concentration of Carbon dioxide is higher inside, hence it will move towards the outside due to diffusion.
On the other side, the statements are showing oxygen, proteins, and glucose are moving against the concentration gradient.
Therefore, Carbon dioxide will diffuse out of the cell in the given picture. Option C is correct.

The anticoagulant in a gray-topped tube _________ when collecting specimens for alanine aminotransferase (ALT) or aspartate aminotransferase (AST).
The anticoagulant in a gray-topped tube destroys many enzymes when collecting specimens for ALT or AST. This grey-top tube contains potassium oxalate and sodium fluoride.
The gray-topped tube has potassium oxalate which acts as an anticoagulant that can destroy different enzymes, it is used for the determination of glucose in a plasma sample.
This tube also contains sodium fluoride, which enables the preservation of glucose in the whole blood during specific tests.
Sodium fluoride can inhibit the activity of enolase, which is a key enzyme involved in the last stages of glycolysis.

what is the term that is used to describe short-lived, local changes in the membrane potential in a neuron?
Graded potential is the term which is used top describe local changes which
are short-lived.
Graded potential are temporary changes that occurs in the membrane
voltage as a result of differences experienced in stimuli
Graded potential experiences a decrease with as more distance is covered
in the membrane and the magnitude has a direct relationship with the
strength of the signal/stimuli. They help to increase the functions of the
neurons and nervous system as a whole.

6. If you know the mass of an object, you can calculate its weight with the formula
a. F=mx9.8 m
b. F=mx9.8 m/s
C. F=mx9.8m/s2
d. F=mx0.98 m/s2
Answer:
4. 2 m/s²
5. Two of the above (both N and kg.m/s² are equivalent)
6. F = m×9.8m/s²
Explanation:
4.
Force = mass × acceleration
40 = 20 × a
a = 40/20
a = 2
5.
Force (in N) = mass (in kg) × acceleration (m/s²)
so the units are equivalent:
N = kg.m/s²
6.
Force = mass × gravity
This is an adaptation of:
Force = mass × acceleration
Gravity is an acceleration of 9.8m/s²
