Explanation

The embryological stages of all vertebrates show similarities in anatomical features, reflecting a common evolutionary origin.

Explanation

λ (lambda) is indeed the decay constant. 

The decay constant, λ "lambda", the reciprocal of the mean lifetime (in s−1), sometimes referred to as simply decay rate
The mean lifetime, τ "tau", is the average lifetime (1/e life) of a radioactive particle before decay.

These are related as follows:

Explanation

Inductance ($L$) is primarily influenced by the following factors:

1. Number of Turns:

   The inductance increases with an increase in the number of turns in the coil. More turns create a stronger magnetic field, which enhances inductance.

2. Area of the Coil:

   The larger the cross-sectional area of the coil, the greater the inductance, as it can enclose more magnetic flux.

3. Length of the Coil:

   The inductance decreases with an increase in the length of the coil. A longer coil has a weaker magnetic field for a given current.

4. Core Material:

   The material around which the coil is wound (the core) affects inductance. Ferromagnetic materials increase inductance due to their higher permeability compared to air or non-magnetic materials.

Explanation

In an adiabatic process, when the volume of a gas decreases, the temperature of the gas increases.

• In an adiabatic process, no heat is exchanged with the surroundings.
  
• When the volume decreases, the gas is compressed, and work is done on the gas.
• This work increases the internal energy of the gas, which raises its temperature.

Explanation

The mantle is a feature of mussels and other mollusks, responsible for secreting the shell.

Explanation

When two waves of the same frequency and amplitude meet in phase, they align perfectly at their peaks and troughs.

This results in constructive interference, where the amplitudes of the waves add together.

Explanation

Enzymes catalyze reactions by lowering the activation energy required for the conversion of substrates into products.

Explanation

Humulin (human insulin) is produced using bacteria through recombinant DNA technology.

Explanation

Oxidation of a secondary alcohol results in the formation of a ketone.
