Since D and E are siblings, and no other children are mentioned, E is the youngest.

C is the cousin of D, as D is A's sister and A is C's parent.

G is H's niece or nephew, as H is E's brother and E is G's parent.

The order of age is Mother > Son > Daughter. Therefore, the Daughter is the youngest.

The mother is the oldest as she is older than the father.

The order of ages is Y < V < W < X < Z. Therefore, Z is the oldest sibling.

C is D's cousin as they are children of siblings.

C is the child of B, and D is the sibling of B, making C and D siblings.

C is the grandchild of A, making C the grandnephew of D.

D is the sister of C, who is married to B's father, making D the daughter-in-law of A.

D is the sister of A, making her the sister-in-law of C.

C is the niece of D as D is the sister of A, the grandmother.

The grandfather has 2 sons, so he has 2 children.

The other son must also be a lawyer, as he is the brother of the father who is a doctor.

The eldest child is studying engineering, so he is an engineer.

The youngest child is likely unemployed as they are not mentioned to have a profession.

The profession of the youngest child is not specified.

The third child must be a student, as stated in the question.

The children are siblings to each other and children of the parents.

Ethanol produced per kg of glucose = 1.5 kg / 2 kg = 0.75 kg. For 8 kg of glucose, ethanol produced = 0.75 kg * 8 kg = 6 kg.

Yield percentage = (yield of product / amount of substrate) × 100 = (80 g / 1000 g) × 100 = 8%.

An inode is a data structure that stores metadata about a file, such as its size and location.

Using the first-order rate equation, k = (ln[A₀] - ln[A]) / t. Here, k = (ln(0.8) - ln(0.2)) / 20 = 0.0347 min⁻¹.

In a first-order reaction, the half-life is independent of the concentration of the reactant, so it remains the same.

In a first-order reaction, the half-life is constant, which indicates that the rate constant remains constant.

t₁/₂ = 0.693 / k = 0.693 / 0.03 = 23.1 min.

The pressure at a depth h in a fluid is given by P = ρgh, where ρ is the fluid density and g is the acceleration due to gravity.

In a fluid at rest, the pressure at a point depends on the depth of the fluid above that point.

In a fluid at rest, the pressure at a point depends on the height of the fluid column above it, as described by hydrostatic pressure.

Laminar flow refers to fluid motion in parallel layers with no disruption between them.
