Explanation

In 1969, Whittaker proposed a system of classification that divided all living organisms into five kingdoms:

1. Monera (bacteria and cyanobacteria)
2. Protista (protozoa, algae, and slime molds)
3. Fungi (mushrooms, molds, and yeasts)
4. Plantae (plants)
5. Animalia (animals)

Explanation

• As temperature increases, the heat energy of a substance also increases.
• This is because temperature is a measure of the average kinetic energy of the particles in a substance, and as temperature increases, the particles gain kinetic energy and therefore heat energy.

Explanation

• Marasmus is a severe form of protein-energy malnutrition that affects infants and young children, typically under the age of 5.
• It is characterized by wasting of fat and muscle, stunted growth, and developmental delays.

Explanation

Copper is an essential mineral found in various foods, including:

• Whole wheat
• Bananas
• Peas
• Prunes
• Oysters
• Liver
• Kidney
• Grains (quinoa, brown rice)
• Legumes (lentils, chickpeas)

Copper is Crucial for:

• Formation of red blood cells.
• Helps with the functioning of the nervous system.

Note: According to Sindh Textbook Board, Jamshoro

Explanation

• Peanuts are a legume and a good source of protein, containing about 20.5 grams of protein per 100 grams.
• Apples: 0.3 grams of protein per medium-sized fruit
• Watermelon: 0.6 grams of protein per cup
• Mango: 1.4 grams of protein per cup

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.
