Explanation

Protozoa are single-celled eukaryotic organisms (meaning they have a nucleus) and heterotrophic (meaning they cannot produce their food and must consume it).

These characteristics are also shared by animals. 

Explanation

The major inorganic component of vertebrate bone is Calcium phosphate. 

Calcium phosphate is the primary mineral found in bones, making it the predominant inorganic constituent. 

Explanation

Speed = 3000 RPM (revolutions per minute)

Step 1: Convert RPM to revolutions per second (RPS)

Step 2: Convert revolutions to radians

Since 1 revolution = 2π radians:

50 rev/sec×2π= 100π radians/sec

Explanation

Electric Flux Maximum (Φ = E·A·cosθ)  

   - When the area vector is perpendicular to the electric field, θ = 0°, so cosθ = 1.  

   - Therefore, Φ = EA (maximum possible flux). 

Explanation

Glass, iron, plastic, and paper are typically considered non-recyclable domestic waste;

They are generally accepted for recycling in most communities

Explanation

The reverse process of the photoelectric effect is the production of X-rays when electrons are decelerated.

In the photoelectric effect, light (photons) interacts with a material, causing electrons to be emitted.

Explanation

 The penetration of a virus into a host cell is facilitated by sugars on the viral surface interacting with specific receptors on the host cell membrane, allowing the virus to attach and enter the cell. 

Explanation

Electrostatics is the branch of physics that deals with the study of stationary electric charges, also known as static electricity.

It involves the study of electric charges at rest, their properties, and the forces that act upon them.

Explanation

Serum differs from blood in lacking clotting factors.

It is separated from the blood when a blood sample is allowed to clot

And further centrifuged to separate the red blood cells and the clot.

It does not contain any proteins required for the clotting of blood.

Explanation

Devonian Period is spanning between about 419.2 million and 358.9 million years ago 

It was In geologic time, an interval of the Paleozoic Era

It is sometimes called the “Age of Fishes”

Plants, invertebrates, and other vertebrate lifeforms also experienced major changes in the Devonian

Additional informational:

The name of the Devonian Period is derived from the county of Devon, Eng.

During most of the Devonian Period, North America, Greenland, and Europe were united into a single Northern Hemisphere landmass
