Explanation

In birds, gas exchange occurs in the lungs as air moves through small tubes (parabronchi) in one direction; in mammals, air flows tidally into and out of the alveoli.

Explanation

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

Explanation

Passive immunity is when an individual receives antibodies from an external source, such as from a mother's milk.

Explanation

The link reaction (pyruvate to acetyl-CoA), Kreb's cycle (citric acid cycle), and the electron transport chain all occur in the mitochondria.

Explanation

To find which body has the largest kinetic energy, we use the formula for kinetic energy:

Mass = 2M, Speed = 3V

$$$$K.E.d=12⋅2M⋅(3V)2

$$$$
=12⋅2M⋅9V2

$$text{K.E.}_d = frac{1}{2} cdot 2M cdot (3V)^2 = frac{1}{2} cdot 2M cdot 9V^2 = 9MV^2$$K.E.d​=1​/2⋅2M⋅(3V)^2=1/2​⋅2M⋅9V^2=9MV^2

Explanation

Explanation

When alcohol reacts with sodium, it produces alkoxide ions and hydrogen gas.

Explanation

Pyridine is a six-membered ring with nitrogen in its structure, which makes it a heterocyclic compound.

Explanation

Cutting trees can result in the loss of habitat for animal species, which can harm ecosystems.

Explanation

The brightness of the waveform on the screen of a Cathode Ray Oscilloscope (CRO) is primarily controlled by the potential of the cathode.

Here's why:

• Cathode Ray Tube (CRT)
• Electron Beam Intensity
• Potential of the Cathode
