Microfilaments are thin strands of the contractile protein composed of myosin. Select one: True False
zzz [600]

Answer:

The given statement is false.

Explanation:

Microfilaments refer to the solid rods formed of a protein called actin. Microfilaments are also considered as actin filaments. It is found in all the cells of eukaryotes, the microfilaments are mainly structural in function and are an essential constituent of the cytoskeleton, along with intermediate filaments and microtubules.  

Microfilaments vary from 5 to 9 nm in diameter and are developed to withstand huge amounts of tension. With myosin, microfilaments assist in generating the forces used in basic cell motions and cellular contraction. The microfilaments also allow a differentiating cell to separate into two cells and also take part in amoeboid movements of some kind of cells.

Why do third level consumers gain was energy from their food
LenaWriter [7]

Third-level consumers, or tertiary consumers, are carnivores who eat primary and secondary consumers. This almost NEVER happens, but there is sometimes a level higher than the tertiary consumers that eats them. It rarely happens, so often the tertiary consumers do not get eaten. Also, as tertiary consumers eat the primary and secondary consumers, they receive 10% of their energy from the producers. What happens with that 90%? Well, the 90%, most of the time, is lost to the environment as heat. Anyway, there more tertiary consumers besides the red fox, like the eagle, for instance, but there aren't many of the tertiary consumers because there isn't enough energy to get to them, since only 10% is being transferred each time a predator eats a prey in the food chain.
