 The non-protein part of an enzyme is called a cofactor. 

Explanation

Let's assume the maximum marks in each subject are 100. Then, the student's total marks in the three subjects are:

75 + 80 + 85 = 240

If the marks of another subject are added, the total marks become:

240 + x (where x is the marks obtained in the fourth subject)

The average percentage cannot be less than 60% because:

• If the student scores 0 in the fourth subject, the total marks would be 240, and the average percentage would be (240/400) x 100% = 60%.
• If the student scores any marks in the fourth subject, the average percentage would be higher than 60%.

Explanation

The kinetic molecular theory states that gases are made up of small particles called molecules.

These molecules are in constant random motion and collide with each other and the container walls.

Explanation

Explanation

The equation |-x| = 0 simplifies to x = 0 since the absolute value of any number is zero only when the number itself is zero.

Therefore, the solution set contains only {0}.

Explanation

Normal fasting glucose concentration in blood plasma is ~70–100 mg/dL.

It translates to ~0.1% (100 mg/dL = 0.1 g/dL = 0.1%).
