Explanation

Silver nitrate (AgNO3) is a strong oxidizing agent and a caustic substance.

It is also known as "lunar caustic" due to its historical use to treat lunar burns (sunburn).

Explanation

In flowering plants, xylem is composed of four types of tissues:

1. Tracheids
2. Vessel elements
3. Xylem fibers
4. Xylem parenchyma

Explanation

Starch is a type of carbohydrate that is quickly digested by the body.

It is a complex carbohydrate made up of long chains of glucose molecules.

It found in foods such as bread, pasta, and potatoes.

Explanation

The cell cycle is also known as the cell division cycle.

It is the sequence of changes that occurs between one cell division and the next.

Explanation

• The odd one out is: Ratio
• Theory, Law, and Hypothesis are all related to the scientific method.

Explanation

Heat capacity is the amount of heat energy required to change the temperature of a substance by a given amount.

It is calculated as the product of the mass of the substance and its specific heat capacity:

Heat Capacity = mass x specific heat capacity

Explanation

Coal, gas, and oil are all examples of fossil fuels, which are energy resources formed from the remains of ancient plants and animals over millions of years.

Fossil fuels are non-renewable sources of energy.

Additional Information:

• Tidal energy is energy generated from ocean tides
• Nuclear energy is energy generated from the nucleus of atoms
• Biomass energy is energy generated from organic matter (plants, wood, waste)

Explanation

When a gas is heated in a sealed cylinder:

• The temperature of the gas increases (by definition of heating).
• The average kinetic energy of the particles increases (as the temperature rises, the molecules move faster).
• The pressure inside the container increases (as the molecules move faster and collide more frequently with the container walls).

Explanation

• Carbon-12 (C-12) is the most abundant of the two stable isotopes of carbon, amounting to 98.93% of elemental carbon on Earth.
• Carbon-12 is composed of six protons, six neutrons, and six electrons.
• The atomic mass of carbon-12 is exactly 12 Dalton's, by definition.

Explanation

Human plasma proteins consist of:

• Fibrinogen (A): involved in blood clotting
• Albumin (C): helps regulate blood volume and transport various molecules
