Explanation

• The freezing point of a liquid can be affected by pressure.
• This is known as the "pressure melting point" effect.
• As pressure increases, the freezing point of a liquid can also increase.

Explanation

• Henry Moseley's famous work in 1913 showed that the chemical properties of elements are a periodic function of their atomic number (Z), not their atomic mass.
• This discovery led to the modern periodic table, where elements are arranged in order of increasing atomic number (Z), rather than atomic mass.

Explanation

• Osmosis is the movement of water molecules from an area of higher water potential (high concentration of water molecules) to an area of lower water potential (low concentration of water molecules) through a selectively permeable membrane.
• This process helps to equalize the concentration of water molecules on both sides of the membrane.

Explanation

• Phloem is the vascular tissue responsible for transporting organic materials, such as sugars, amino acids, and other nutrients.
• Produced by photosynthesis from the leaves to the rest of the plant, including roots, stems, and fruits.

Explanation

• The correct sequence of biological method is: Hypothesis → Reasoning → Theory → Law

This sequence represents the scientific method in biology, which involves:

• Formulating a hypothesis (a educated guess) to explain a phenomenon
• Using reasoning and logic to develop predictions and test the hypothesis
• Developing a theory (a well-substantiated explanation) based on the results of experiments and observations
• Establishing a law (a universal principle) that describes the phenomenon

Explanation

• Fisheries refer to the industry or practice of catching, breeding, and managing fish and other aquatic organisms.
• Increased quantity and quality of fish production is a result of improvements in fisheries management, aquaculture (fish farming), and fishing technologies.

Explanation

Never connect ohm meter on live circuits to avoid electric shock or damage.

Explanation

The Tetanus toxoid vaccine is typically injected into the muscle of the upper arm.

This intramuscular injection ensures effective absorption and immune response.

Explanation

The bond formed between water molecules (H2O) is a hydrogen bond.

The bond within the water molecule itself is a covalent bond

Explanation

• Red meat is a good source of protein and other nutrients.
• It is not a significant source of calcium.
