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.

how long does it take a skateboarder going 6.0 m/s to come to a complete stop if she slows down at a rate of 2.0 m/s^2
emmasim [6.3K]

Use the formula: v=v0+at

v is the final velocity

v0 is the initial velocity

a is the acceleration

t is the time


Plug in and solve for t:

0=6+(-2)t

<em>*Subtract 6 from both sides*</em>

-6=-2t

<em>*Divide both sides by -2*</em>

3 seconds=t


Hope this helps!!

During exercise, muscle cells release the protein ________ which can cause brite/beige adipocyte formation:
shepuryov [24]

Answer: Option "D".

Explanation: During exercise muscle cells release irisin protein is being released causing Beige adipocyte formation.

the secretion of Irisin leads to the improvement in muscle activity, bone mineral density, increasing the formation of brown like Beige adipocytes in the tissue.

Adipocytes are divided into two tissues namely white and brown. white tissues generally expand during excessive nutrition and brown adipocytes have mitochondria and burn the energy during exercises resulting into the break down of ATP  molecules increasing the body heat.  

Therefore, during exercise heat generated due to the formation of brown adipocyte tissue which are formed due to the release of irisin protein.
