Explanation

As a rocket moves upward, its acceleration increases continuously. 

This is because as the rocket burns fuel and expels exhaust gases, its mass decreases.

According to Newton's second law of motion (F = ma), with a constant force (the engine's thrust), a decreasing mass results in an increasing acceleration. 

Explanation

The retention factor (Rf) in chromatography is a unitless value

Because it is calculated as a ratio of two distances (distance traveled by the solute and distance traveled by the solvent), the units of length cancel out. 

Explanation

The ion primarily involved in initiating and regulating muscle contraction is calcium (Ca²⁺).

While magnesium (Mg²⁺) also plays a role in muscle relaxation and overall function,

Calcium is the key player in triggering the contraction process. 

Explanation

Cinnabar is the most common ore of mercury, and its chemical formula is HgS (mercury sulfide).

It has a bright red color and is used to extract mercury.

Explanation

 The limiting reactant (or limiting reagent) is the reactant that controls the amount of product formed in a chemical reaction

Because it is the substance that is completely consumed first, thereby limiting the extent of the reaction. 

Explanation

Enterokinase cleavage is carried out at an enzyme/substrate ratio (w/w) of 1/20-1/200 for 1-24 h.

For each fusion protein pilot experiments should be done to find out suitable conditions.

The optimal pH for the reaction is between 7.0-8.0, but the enzyme can be used within pH 6.0-8.5

Explanation

 The trochophore larva is a characteristic larval stage found in several marine invertebrates.

Most notably within the phyla Annelida (segmented worms) and Mollusca (mollusks).

It is also present in other groups within the superphylum Lophotrochozoa, including entoprocts, nemerteans, echiurans, and sipunculans.
