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

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.

Explanation

In plants, the cell wall is primarily composed of strong fibers of cellulose, a type of carbohydrate.

Cellulose is a polymer of glucose molecules that provides structural support, rigidity, and protection to the plant cell.

Explanation

• The cortex is the layer of tissue between the epidermis (outermost layer) and endodermis (inner layer) in plant roots.
• It's a region of parenchymatous cells that stores food, water, and nutrients.

Explanation

All three processes allow movement in and out of cells:

• Osmosis: Movement of water molecules from high concentration to low concentration through a selectively permeable membrane.
• Diffusion: Random movement of molecules from high concentration to low concentration until equilibrium is reached.
• Active transport: Movement of molecules from low concentration to high concentration using energy (ATP) to pump molecules across the cell membrane.

Explanation

• Tables and graphs are both essential methods for organizing and visualizing data, and they complement each other.

Tables are useful for:

• Displaying precise values and data points
• Organizing large datasets
• Performing calculations and data analysis

Graphs are useful for:

• Visualizing trends and patterns
• Displaying relationships between variables
• Communicating complex data insights effectively

Explanation

Leukemia is a type of cancer that affects the blood, bone marrow, and lymphatic system.

It occurs when there is an abnormal growth of white blood cells, which can crowd out healthy cells and platelets.

Explanation

The pancreas secretes pancreatic juice, which contains a variety of enzymes that help break down carbohydrates, proteins, and fats in the small intestine.

These enzymes include amylase, lipase, trypsin, and chymotrypsin, among others.

Explanation

A scientific law is a statement that describes a consistent and universal pattern of natural behavior.

It is often considered an irrefutable theory.

Examples of scientific laws include the Law of Gravity, the Laws of Motion, and the Law of Conservation of Energy.

Explanation

In the five-kingdom system, viruses are not placed in any of the five kingdoms:

1. Monera (bacteria)
2. Protista (eukaryotic organisms)
3. Plantae (plants)
4. Animalia (animals)
5. Fungi (fungi)

Viruses are considered non-living entities.

So, in the five-kingdom system, viruses are not classified in any of the five kingdoms.
