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

• 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

• A population is a localized group of organisms that belong to the same species and live in a specific geographic area.
• It is a unit of evolution, and its members share a common gene pool.

Explanation

• A spacecraft is a man-made object designed to perform specific tasks in space.
• Such as exploration, communication, or research. 
• Examples of spacecraft include satellites, space stations, and probes.

Explanation

• A Spectroscope is used to identify the chemical elements present in a star and determine its composition.
• By analyzing the light spectrum, astronomers can also determine the star's temperature, velocity, and distance from Earth.

Explanation

• A spectrum of light is the distribution of light into its individual colours.
• Typically displayed in the order of red, orange, yellow, green, blue, indigo, and violet (ROYGBIV).
• This is often seen in the form of a rainbow or produced through the use of a prism.

Explanation

A refracting telescope has two lenses:

1. A primary lens (objective) that collects and focuses light.
2. A secondary lens (eyepiece) that magnifies the focused light to form an image.

Explanation

• Silicon is an example of a Semiconductor.
• Semiconductors like silicon have electrical conductivity between conductors and insulators.
• It enabling them to control electrical current flow in devices and integrated circuits.

Explanation

• The electricity used in homes and schools is typically Alternating Current (AC).
• It is the type of electric current that periodically changes direction.
• This is the type of current provided by power plants and distributed through the grid.

Explanation

• Alternating Current (AC) is the flow of electric charge that periodically changes direction.
• This type of current is commonly used in power distribution systems and household electrical outlets.
