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

The cell membrane is also known as the plasma membrane.

It is composed of a double layer of lipids, specifically phospholipids.

Explanation

Each mole of ATP (Adenosine Triphosphate) stores energy equivalent to:

• 7.3 kilocalories (kcal) per mole (approximately)
• 17.3 kilojoules (kJ) per mole (approximately)

Explanation

Fish is an excellent source of protein.

It is essential for building and repairing muscles, organs, and tissues in the body.

Explanation

Metabolic reactions are both constructive (anabolic) and destructive (catabolic) reactions.

Explanation

Chloroplasts contain various pigments like chlorophyll, carotenoids, and phycobiliproteins, which absorb light of different wavelengths.

This allows plants to capture a broad spectrum of light energy and use it for photosynthesis.

Explanation

The presence of an enzyme does not affect the nature or properties of the end products of a chemical reaction.

Enzymes only speed up the reaction, they do not change the final result.

The end products are the same, regardless of whether an enzyme is present or not.
