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

 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

Explanation

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

Explanation

• “Trout fish” is found in Northern Areas
• ***
• The trout fishery of Pakistan prevails particularly in the NWFP and Northern Areas,
• where two species of trout, though exotic in origin, have established themselves in rivers of this province.
• They are brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss).
• Three main rivers, Neelum, Sindh, and Jhelum (Lidder), have been the principal sources of Trout,
  

Explanation

A hydrogen-filled balloon expands as it rises and may even burst after rising very high in the atmosphere

As one goes high, the weight of the atmosphere above decreases and so does the pressure.

Thus for a balloon filled on the ground, the pressure inside the balloon exceeds that outside and thus it bursts.
