If muscles did not generate opposing forces, then the contraction and relaxation of muscles leading to movement will be limited.
Explanation:
Basically skeletal muscles work in pairs of agonist and antagonist muscles which work together but with opposing forces to contract and relax respectively. These opposing forces help to facilitate movement. Like in a bicep curl, the biceps work as agonist and triceps work as antagonist. The muscular strength is the force that acts against the opposing force of muscles. This strength is regardless of age, sex, weight or size of an individual.

Answer:
<em>mutualism, parasitism, adaptive radiation).</em>
Explanation:
Some species of hummingbirds have different shapes of beaks that evolved to allow them to drink from certain flowers. the flower species have evolved to produce nectar that is tasty for the hummingbirds. this example is a type of (coevolution, convergent evolution, adaptive radiation). cuckoos lay eggs in the nests of other birds. the cuckoo lays eggs identical to the eggs of the host species, so the other bird takes care of it. this is an example of (mutualism, parasitism, adaptive radiation).
<span>Cell membranes protect the cells that is why they are called the gatekeepers of the cell. A cell membrane can be internal or external like that of the case of eukaryotic cells with internal cell membrane. It is mostly made up of glycerophospholipids. This compound like other lipids is also soluble in water however, their unique geometry allows them to aggregate into bilayers without too much energy input. Cholesterol can also be found in the cell membranes however, it is not as abundant as the glycerophospholipids.</span>
