Explanation

The number of loops in stationary waves depends on the wavelength of the waves. 

A longer wavelength means fewer loops fit within a given length, and vice versa, so the number of loops is directly related to the wavelength. 

Explanation

Carbon Dioxide, Water, and Sand are common and effective methods used for extinguishing fires.

There are six types of fires, and different extinguishing materials are used to extinguish them.

The fire types are

1. Class A
2. Class B
3. Class C
4. Class D
5. Class E
6. Class F

Explanation

Yellow cytoplasm in Ascidian cells gives rise to muscle cells. 

In ascidians, a type of marine invertebrate, the yellow cytoplasm is a distinct region of the fertilized egg that contains specific molecules responsible for muscle development.

Cells that inherit this yellow cytoplasm during cell division will differentiate into muscle cells.

This is why the correct answer is c. Muscle cell. 

Explanation

 An autotrophic organism is an organism that produces its food, so the correct answer is Algae. 

Algae use photosynthesis to create their own food from sunlight, water, and carbon dioxide, making them a prime example of an autotroph. 

Explanation

• One parallel to the field (causes straight motion)
• One perpendicular to the field (causes circular motion)

Explanation

A cell counter is a device specifically designed to count the number of cells in a suspension.

This is crucial in cell culture experiments, as researchers need to know the cell concentration before seeding or performing other procedures. 

Explanation

Explanation

The percentage yield is the most common measure of efficiency in chemical reactions, comparing actual yield to theoretical yield.
