What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..

Enolase is an enzyme that catalyzes one reaction in glycolysis in all organisms that carry out this process. The amino acid sequ

julia-pushkina [17]

Answer:

Explanation:

a) Ph that is below or above the optimal range will result in enzyme activity loss. if the pH changes above or below optimum range affects the charges that is present on the amino acid molecules. Amino acids presrnt in the active site of enzymes that attracted each other may no longer continue to be attracted. Again, the shape of the active site of the enzyme changes due to the substrate binding will be affected. conclusively, we can say that the enzymes are denatured.

b) researchers are most likely to use a negative control when measuring the rate of reaction in the presence of each organisms. enolase is controlled with no enzyme.

c) c) Since the C.aurantiacus grows best at 550C , we can say that the enzymes that they produce must be at this temperature and so they must be sensitive to this temperature ; hence they would show more activity at 550C temperature.
