D Correct answer
Explanation

The liver is the organ responsible for the production of bile, which is then stored in the gallbladder. The pancreas produces digestive enzymes and insulin, while lachrymal and salivary glands produce tears and saliva respectively.

C Correct answer
Explanation

When multiplying 0.1 by 0.1, we multiply 1 by 1 to get 1, then count the total decimal places (2) and place the decimal point accordingly, resulting in 0.01. This is fundamental decimal multiplication.

B Correct answer
Explanation

When adding 0.1 and 0.1, we simply add the numbers: 0.1 + 0.1 = 0.2. This is straightforward decimal addition where we align decimal points and add the values.

B,C Correct answer
Explanation

When subtracting 0.1 from 0.1, the result is 0. Both '0' and '0.0' represent the same numerical value of zero, with the latter showing the decimal explicitly. This is correct.

D Correct answer
Explanation

When dividing 0.1 by 0.1, any non-zero number divided by itself equals 1. This is a fundamental division property: a ÷ a = 1 for any non-zero a. Therefore 0.1 ÷ 0.1 = 1.

  3. negative infinity

  4. infinity

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The logarithm of 0 is undefined in real numbers. As x approaches 0 from the positive side, log(x) approaches negative infinity because you're asking "what power must I raise the base to, to get 0?" - no real number works.

  4. can not be determined

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The logarithm of 1 is always 0 in any base, because any number raised to the power of 0 equals 1. This is a fundamental property of logarithms: log_b(1) = 0 for all bases b > 0, b ≠ 1.
