Which of the following statements about muscles is false? Muscles typically work in pairs, with one contracting while the other relaxes. Muscles are responsible for maintaining balance Muscles can generate tremendous force but have little endurance The muscular system makes up approximately 10 percent of body weight.

-Muscles can generate tremendous force but have little endurance and,

- The muscular system makes up approximately 10 percent of body weight.

These statements are false about muscles.

Explanation:

Muscles can be referred to simply as the flesh mostly associated with bones to give shape to the bodies of humans and animals. There are three types of muscle which includes:

- unstriped muscle ( smooth muscle),

- striped muscle( skeletal muscle) and

- cardiac muscle ( heart muscle).

The general properties of muscular system includes:

-All muscular tissues are contractile which helps in body movement. Muscles typically work in pairs an example is the triceps and biceps. While the biceps contracts, the triceps relaxes to move the arm.

- muscles are effectors: that is, they are structure which respond directly or indirectly to structures thereby maintaining balance.

- muscles has the ability to generate force but intensity of training determines whether there will be increased muscular endurance or not.

- muscles account for about 40% of the total body weight of mammal not 10%.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
