Which describes an interaction within the musculoskeletal system?A.) When a muscle contracts, a bone will move.
B.) When a bone contracts, a muscle will move.
C.) When a tendon contracts, a ligament will move.
D.) When a ligament contracts, a tendon will move.

Answers

The option that describes an interaction within the musculoskeletal system is when a muscle contracts, a bone will move. Thus, the correct option is A.

What is the Musculoskeletal system?

The Musculoskeletal system may be defined as the system in the body that comprises muscle cells, tissues, and other linkages that bring out the movement of a specific organ.

Tendons are the part that connects muscles to bone and when muscle contracts, it will allow to move the bone as well.

Therefore, the correct option for is question is A.

#SPJ2

The correct answer is A.
Skeletal muscles are connected to the bones with various types of connective tissue like tendons. Bones and connective tissue lack the structural elements needed for contraction and movement, so the only way to move them is by moving the muscles.The complex structure of the muscle fibers enables the muscles to contract and move, moving the bones at the same time.

Which of the following continents was not covered by ice during the Pleistocene ice age? a. Europe
b. Asia

What is one advantage of their use as a green agricultural practice compared with conventional agricultural practices?

a. it prevents water pollution.

b. it prevents air pollution.

c. it prevents soil erosion.

d. it protects endangered species.

Answers

Answer:

A. It prevents water pollution

Explanation:

Conventional methods of agricultural pest control involves the use of pesticides. These pesticides are usually chemicals which are harmful to the organisms involved. However, since these chemicals are not easily degraded, they enter the runoff when rain falls, flowing into nearby streams and rivers, thereby polluting them.

However, with natural pest control methods like the use of ladybirds to destroy aphids, there would be no need for chemicals which will eventually pollute any nearby water environment.
