Answer:
a
Explanation:
if a cell is without water it has a high salinity while fresh water doesnt so the water rushes in and burst the cell
B.) a characteristic that helps an organism find food
C.) a characteristic that evolves
D.) a characteristic that helps an organism avoid predators
B. a = F – m
C. a = Fm
D. a = F divided by m
The answer is D. This means that is you have a determined amount of force (in newtons) being applied on an object of known mass (in kilograms), then to determine the acceleration of the object, divide the force by the mass (or multiplying the force with the inverse of the mass of the object). This behavior of objects is stipulated in Newtons/ second law. Increasing the force increases the acceleration while increasing the mass decreases the acceleration of the object. Acceleration is a vector quantity meaning it has magnitude and direction.
B. The enzyme reaction time would increase.
C. The enzyme reaction time would stay the same.
D. The optimal pH of the enzyme would change.
A. The enzyme reaction time would decrease as any pH level other than that of the optimal will lead to denaturing of the enzyme.
Answer:
A
Explanation:
Answer:
Polymers are made from a chain of one similar subunit bound together in sequence. Proteins are made from polypepetide chains which are sequences of amino acid subunits. Another example of polymer is DNA and RNA made of nucleic acid subunits.
However, lipids do not have one similar subunit but rather variable ways in which the lipid chains can form. For example phospholipid unit is made of a phosphate molecule bound to a fatty acid chain and glycerol. A triglyceride is a subunit of glycerol bound to three fatty acids chains. Cholesterol is also considered a lipid but is made of carbon rings rather than chains. Lipids therefore cannot be referred to as a polymer.
