Explanation

The renewable energy sources are:

• Water energy
• Wind energy
• Tidal energy
• Solar energy
• Hydroelectric
• Ocean energy
• Geothermal energy
• Biomass
• Biogas

The non-renewable energy sources are:

• Fossil fuels or Hydrocarbon fuel (Oil, Natural gas, Coal)
• Nuclear energy

Explanation

• A pair of unlike parallel forces (forces that act in opposite directions) with different lines of force produce a couple.
• It is also known as a moment or torque.
• This is a rotational force that tends to cause rotation around a pivot point or axis.

Explanation

• If the zero line of the Vernier scale coincides with the zero of the main scale, it means that there is no zero error.
• Zero error occurs when the zero of the Vernier scale is not aligned with the zero of the main scale, resulting in a systematic error in the measurements.

Explanation

To find the area of the chip wrapper, you multiply the length by the width:

Area = Length x Width

= 4.5 cm x 5.9 cm

= 26.55 cm^2

So, the area of the chip wrapper is 26.55 cm^2.

Explanation

• One atmospheric pressure, also known as standard atmospheric pressure.
• It is defined as 101325 Pascals (Pa).
• This is the pressure exerted by the weight of the atmosphere at sea level.
• It is used as a standard unit of pressure.

Explanation

• The diagram that shows atoms are bonded with the same electronegativity is: A -----:----- B.
• In this representation, the bond is shown with a symmetrical distribution of electrons.
• It suggesting that the atoms have the same or very similar electronegativity.

Explanation

• The Fats is Lipid or Fatty acid, not Starch.
• Starch is a type of carbohydrate.

Explanation

• Biophysics is an interdisciplinary field that applies the laws and techniques of physics to study the structure, function, and behavior of living systems, from molecules to entire organisms.
• It seeks to understand the physical principles underlying biological processes, such as energy transfer, transport, and signaling.

Explanation

• Plants store the glucose produced during photosynthesis in the form of starch.
• A complex carbohydrate made up of many glucose molecules.
• Starch is stored in the plants roots, stems, leaves, and seeds, and serves as a energy reserve for the plant.

Explanation

The active site is a small region on the surface of an enzyme where the substrate binds, allowing the enzyme to catalyze the chemical reaction.

It is a highly specific region that is shaped to fit the substrate, allowing for efficient binding and catalysis.
