1. Explain how muscles work in pairs in moving limbs.
as one muscle contracts its opposite muscle relaxes, and to move that bone back to the prior position then the oposite muscle contract and the other muscle relaxes
2. Identify the structures that make up a skeletal muscle.
2. Identify the structures that make up a skeletal muscle.
muscle fiber, myofibrils, sacromere, thin filaments (actin), thick filaments (myosin)
3. Identify at least three organ systems involved in a handshake. Describe what each system contributes to the handshake.
3. Identify at least three organ systems involved in a handshake. Describe what each system contributes to the handshake.
skeletal system: support and rigidness
muscular: make the movement happen
nervous: controls the operation by controlling when and to where you move your hand
4. Explain how actin and myosin interact as a muscle cell contracts.
4. Explain how actin and myosin interact as a muscle cell contracts.
Atp is used to make them come closer or far away, as they move far away the muscle contracts and as the move close together the muscle relaxes
Hi Francisco! i liked how you made easy and concise answers, such as the one of the first question because you explain with easy vocabulary (contract, relax). Also,you were able to give a full explanation of it in a small sentence. Good job!
ReplyDeleteYour answers were really clear but however, in question number 4 i would have included the entire process and explain it in more detail for example how myosin heads interact with ATP.
ReplyDeleteI think answers are explained crearly, except in number 4, it is hard to understand how myosin and actin work together and how the process uses ATP for contractions and relaxations.

ReplyDeleteFraccisco you expressed your thoughts in a clear and consise way. in question 3 you needed to have one more organ and to explain a little more about each organ.
