Answer:
Increasing the surface area of a solid has no effect on the speed of dissolving. Hence, the correct answer is option B.
Explanation:
The increasing of surface area has no effect on the speed of dissolving at as it is irrelevant with the dissolving speed with the solvent. The dissolving effect air speed can be altered with the temperature and with the volume but is increasing of surface area has no relevance on the dissolving speed.
If the temperature is raised above the room temperature it helps in dissolving speed and dissolving quantity. The increase of surface area can we done by various ways such as expanding through mechanical method, etc.
Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.

The main difference between prokaryotes and eukaryotes is the presence of nucleus in eukaryotes and its absence in prokaryotes. Also, prokaryotes are unicellular, so one cell is a whole organism. On the other hand, eukaryotes are mainly multicellular, and thus more complex. More complex DNA is inside the nucleus in the eukaryotes which enables them to conduct a wider range of functions. Prokaryotes, as a single cell, have simple functions present.
