Answer:

1. Submit your observations of the chicken leg dissection.

The first thing that I saw was the skin. This one has bumps on it. Underneath, when I carefully cut it, I could see a yellow layer which is fat. Under the fat, there is a thick pink tissue, the muscles. The muscle is in contact with the bones and attached to them by the tendons. They look thin and white and are at the muscles' ends since they attach them to the bones.

2. Were you able to determine how the chicken moves?

Yes, muscles work in pairs, so when I pull from a specific tendon, the leg bends since the muscle contracts to do this movement. Then this muscle will relax, another muscle will contract itself, and a tendon will pull the bone to return the leg to a straight position.

When one of these muscles contracts, the other relaxes to allow the bone's movement in a specific direction. Then this muscle relaxes and allows the leg's movement in the opposite direction since the muscle that was lax before now is contracting itself to extend the leg. There are a flexor and an extensor muscle.

3. What characteristics of muscles help you determine the direction of the movement?

The characteristics that help me determine the movement's direction were:

  • The position that the muscles have concerning the joints and the bones.
  • The tendons at the end of the muscles and bones.

By following the muscle, the tendon, and where it is in the joint, I could determine the movement's direction.

Explanation:

When we observe a chicken leg dissection, we can determine the components that it has and how all the elements work together to move the leg. Even though the mechanism and structure are not the same as in a human body, we can see how muscles, bones, tendons, and joints work not only in animals but also in humans to allow movement.

1. What do you notice about the angle of Earth?
Rufina [12.5K]

Answer:

1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.

2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.
