Fast-glycolytic muscle fibers are another name for Type IIb skeletal muscle fibers and are white in color. The skeletal muscle fibers are divided into three types: Slow-contracting muscle fiber (Type I), Fast-contracting muscle fiber (Type IIa) and Fast-contracting muscle fiber (Type IIb).
Fast-glycolytic muscle fibers Type IIb are abundant in muscles of the lower limbs that contract quickly and are oxygen dependent, prevalant in postural muscle of the back, generate lots of power and depend on lots of power and depend on anaerobic pathways to make ATP , have fewer but larger myofilaments and numerous mitochondria, have abundant myoglobin.
Fishes and bottom dwelling worms cope with the fluctuating salinity within estuaries over the tidal cycle with the use of transport system such as active and passive transport.
<h3>How active and passive transport system are used?</h3>
In salty water, fish and other marine organisms used active transport in which energy is used to remove salts from the body of these marine organisms because excess salts are harmful for them.
So we can conclude that Fishes use transport system such as active and passive transport to cope with the fluctuation of salt concentration.

Answer:
four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.
a air front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.
A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.
Stationary Front - a front between warm and cold air masses that is moving very slowly or not at all.
Occluded Front - a composite of two fronts, formed as a cold front overtakes a warm
