Explanation

• Taxonomy is the science of classifying living things, including animals and plants, into groups based on their characteristics, evolutionary relationships, and common ancestors.
• It involves the identification, naming, and classification of species, as well as the study of their relationships and evolutionary history.

Explanation

• Vitamin D serves as a hormone precursor, as it is converted into a hormone in the body.
• Cholesterol also serves as a precursor of vitamin D and steroid hormones.

Explanation

The force exerted on a charged particle by a magnetic field is perpendicular to both the magnetic field and the velocity of the particle. This is described by the Lorentz force equation: F = q (E + v x B)

Where:

• F is the force
• q is the charge
• E is the electric field
• v is the velocity
• B is the magnetic field
• x denotes the cross product

The cross product of two vectors results in a vector that is perpendicular to both of the original vectors.

Therefore, the force due to the magnetic field and velocity is at right angles to each other.

Explanation

• The graph of a linear function is always a straight line.
• Linear functions have the form: f(x) = mx + b
• Where m is the slope and b is the y-intercept. The graph of such a function is a straight line with a constant slope.

Explanation

• OSPF (Open Shortest Path First) establishes route adjacencies on point-to-point links, but does not perform the DR (Designated Router)/BDR (Backup Designated Router) election process on these links.
• This is because point-to-point links only have two routers connected, so there is no need for a DR or BDR.

Explanation

This is the formula for the tangent of the sum of two angles: tan(α + β) = (tanα + tanβ) / (1 - tanαtanβ)

Malic acid is a product of aerobic respiration.

Explanation

• Fastidious refers to someone who is meticulous, demanding, and difficult to please, especially in regards to food, taste, or standards.
• Inflammable: This word means capable of being easily set on fire or ignited, and has no relation to being hard to please.
• Incorrigible: This word means someone who is unable to be corrected or reformed, often in a playful or mischievous sense, but doesn't necessarily imply being hard to please.
• Deteriorate: This word means to become worse or decline in quality, and has no relation to being hard to please.
