Mama L [17]

Answer:

-The three main types of muscle include skeletal, smooth and cardiac.

- Skeletal muscle – the specialised tissue that is attached to bones and allows movement. ...

Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries. ...

Cardiac muscle – the muscle specific to the heart.

-Skeletal muscles are attached to the skeleton by tough connective tissues called tendons

-Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.

-They are lightweight yet strong and hard, and serve multiple functions.

-The joints help attach bones to one another to provide flexibility & allow the muscles to help give the bones a way to move.

- The nervous system helps all the parts of the body to communicate with each other.

-Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body.

-homeostasis?

Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.

Is the DNA in the form of chromatin or chromosomes when a cell finished cytokinesis
Stells [14]

Answer:

Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.

DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.
