Answer:
The skeletal muscle fibres are of two types namely slow-twitch muscle fibres (type I muscle fibre) and fast-twitch muscle fibre (type II muscle fibre).
The slow fibres are slow contracting and help in developing endurance such as long distance running, maintaining posture etc whereas fast fibres are fast contracting and help in movements which require force such as sprinting etc.
Other differences are summarized in a tabular form attached below.
Nucleus – known as the brain of the
cell
Cell membrane – gives protection to
the cell and helps holding together the organelles
Cytoplasm – jelly-like substance that
holds together the organelles.
Endoplasmic Reticulum – consists of
smooth endoplasmic reticulum which lacks ribosomes, and rough endoplasmic reticulum
which has ribosomes.
Ribosomes – consists of RNA and
protein enzyme and helps in protein synthesis
Mitochondria – known as the powerhouse
of the cell and helps transport energy all throughout the cell
Golgi Apparatus – gather proteins and
lipids in the cell and distribute it.
Centrioles – releases spindle like
formations that is attached to the cell in one of the cell division stages
Lysosomes – helps breakdown larger
molecules to smaller molecules
<span>Vacuole – food and water is stored
here. It also store waste material
before it is transported outside of the cell.</span>

Rip currents are caused by breaks or changes in longshore currents.
Waves continually break upon the shore one after the other, they never stop.Water from previous waves runs underneath the waves currently breaking on the shore. This creates a gentle current that runs along the bottom of the ocean, which pull toward the ocean floor. That is mild than a rip current that doesn't present any danger.
