Explanation

A reflex action does not typically involve the brain;

it is usually mediated by the spinal cord, along with sensory and motor neurons.

Explanation

The standard hydrogen electrode (SHE) is used as a reference electrode with an assigned electrode potential of 0 V.

Explanation

 The addition of salt to water decreases the water potential, but osmotic potential will increase.

Explanation

 Carnivorous plants digest animals to supplement their supply of nitrites (nitrogen compounds), which are essential for their growth.

Explanation

The pKb of n-propyl amine is approximately 3.32, indicating its basicity.

Explanation

When an electron moves perpendicular to a magnetic field, the electromagnetic force (also known as the Lorentz force) acting on the electron is given by the formula:

F=qvBsin(θ)

Where:

• $F$ is the force,
• $q$ is the charge of the electron,
• $v$ is the velocity of the electron,
• $B$ is the magnetic field strength,
• $$θtheta is the angle between the velocity vector and the magnetic field.

When the electron is moving perpendicular to the magnetic field, $theta = 90^circ$ and $sin(90^circ) = 1$

Therefore, the force becomes:

$$F=qvB$$

This means the force is at its maximum value since both the charge and the velocity contribute to the force. Thus, the statement that the force acting is maximum is correct.

Explanation

Interferons are cytokines that help activate natural killer cells as part of the immune response

Explanation

Adding more SO₂ – This would increase the yield by shifting the equilibrium toward the product (Le Chatelier's principle).

Explanation

To find the moles, divide the mass of NaOH (60g) by its molar mass (40g/mol). 

Moles = 60/40 =1.5 moles

Explanation

Lenz's law is consistent with the law of conservation of energy because it states that the induced current will always oppose the change that produced it.
