Explanation

The examples of inherited traits in humans, determined by an individual's genetic makeup:

• Colour of hair, skin, and eyes
• Blood group (A, B, AB, O)
• Shape of nose and lips (facial features)

These traits are passed down from parents to offspring through the transmission of genetic information.

Explanation

For two non-linked genes, the probability of obtaining parental-type offspring in the F2 generation is 6/16,

There are 6 possible combinations of the parental genotypes out of 16 total possible combinations.

Explanation

• Scientists who forecast weather by continuously tracking and predicting the path of tornadoes, hurricanes, or floods are called Meteorologists.
• Meteorologists use computer models, satellite data, and other tools to predict weather patterns and warn people of severe weather events.
• It helping to protect lives and property.

Explanation

• Physical quantities are attributes of the physical world, such as length, mass, time, temperature, and energy, that can be measured and quantified.
• Examples of physical quantities include the height of a building, the speed of a car, and the voltage of a battery.

Explanation

• Phenolphthalein is a pH indicator that changes color in response to changes in acidity or basicity.
• In an acidic medium, it is colorless, and in a basic medium, it turns pink.

Explanation

• There is no such nitrogenous base as "Tracil".

The nitrogenous bases are:

1. Adenine (A)
2. Thymine (T)
3. Cytosine (C)
4. Guanine (G)

Explanation

• Cats have a unique audible range that is adapted to their hunting and communication needs.
• They can hear sounds in the range of 45 Hz to 64,000 Hz, which is wider than humans and dogs.

Explanation

• Osmosis is the process where a solvent, typically water.
• It moves through a porous membrane from an area of lower solute concentration to an area of higher solute concentration.

Explanation

• Distillation is a process that removes dissolved physical and chemical impurities from water.
• By boiling the water and then collecting the condensed steam, which is free from many impurities.

Explanation

• The flash of light from lightning is a form of electromagnetic radiation, and as such, it travels at the speed of light.
• It is denoted by the letter c.

It is equal to:

• 3 x 10^8 meters per second (m/s) in scientific notation
• 300,000 kilometers per second (km/s) in metric units
• 186,282 miles per second (mi/s) in imperial units
