Answer:
They became closer to each other.
Explanation:
When skeletal muscles contracts the Z lines that are at the end of every sarcomere became closer to each other due to the fact that the I bands that are attached to the Z lines and contains the myosin filaments move closer to each other interacting with the actin filaments and shorten the the H zone that is in the middle of the sarcomere. In other words, It all becomes compact during a contraction.

Answer:
b) Tendon
Explanation:
Tendons are fibrous, thick, stiff and flexible structures, with a whitish color, present in different parts of the human body.
They are part of the striated muscle being made up of connective tissue (composed of collagen).
The main function of the tendons is to connect the muscles to the bones. In this way, it helps in the balance of the body and in the development of movements, distributing the forces in the muscles.
As it pulls the connecting bone with the muscle, the tendon creates the movement in order to transmit the force of the contraction to the bone.
In addition, the tendon provides stability to the joints (meeting point between two bones) of the body's joints.
There are choices for this question namely:
a. Oil and water
b. Salt and water
c. Brass (and alloy of copper and zinc)
d. Granite (a type of rock with multicolor spots)
The correct answers are
oil and water, and
granite. Heterogenous mixtures are mixtures wherein the solutes can still be identified from each other. Homogenous mixtures are mixtures wherein solutes are completely mixed and cannot be identified. In oil and water, one can identify which is the oil and which is the water. In granite, it is a mixture of different rocks and these different materials can be identified due to the presence of multicolored spots.
