Answer:

When blended liver is exposed to hydrogen peroxide, the catalase enzyme in the liver reacts with the hydrogen peroxide to form oxygen gas, which creates the visible bubbles in this photograph, and water.

Describe the process of skeletal muscle contraction by assembling the following 10 events in the proper order in paragraph form.
balu736 [363]

5) muscle fiber is stimulated at the neuromuscular junction triggering an action potential  

7) APs travel down the T-tubules to the sarcoplasmic reticulum  

Released acetylcholine (due to action potential within motor neuron) from the motor neuron initiates depolarisation within the sarcolemma, which is spread through the muscle fibre via T tubules.

8) in response to an AP, calcium ions are released into the cytosol/space around the myofibrils

Depolarisation causes the sarcoplasmic reticulum to release calcium ions necessary for the contraction

3) calcium ions bind to the T and T system

1) T and T system undergoes a conformational change, exposing the myosin binding sites on actin  

6) myosin head/cross-bridges bind to actin

The binding sites for the myosin heads located on actin, are covered by a blocking complex (troponin and tropomyosin) that can be unblocked by the calcium binding

2) myosin heads/cross bridges bind to actin and flex, shortening the sacromere  

4) actin filaments are pulled toward the center of the sacromere, shortening the muscle fiber  

As the individual sarcomeres become shorten the muscle fibres as a whole contracts

10) myosin head continues to attach, flex, release, extend, and reattach as long as calcium ions are present

9) calcium ions actively transported into the sarcoplasmic reticulum  

Relaxation of a muscle fiber occurs when a Ca ions are pumped back into the sarcoplasmic reticulum .

These statements describe three different reactions.
Arte-miy333 [17]

Answer: 2 - The nucleus of an atom is split apart

Explanation: Any reaction involving the nucleus of an atom is called a nuclear reaction. It is different from ordinary chemical reactions that involve electrons because it involves the release of large amount of energy. Nuclear reactions can be classified as nuclear fission and nuclear fusion.

A nuclear reaction in which a nucleus of an atom is split into two smaller atoms with a release of large amount of energy is called nuclear fission. A nuclear reaction that involves the combination of lighter nuclei of elements to form heavier atoms that are more stable with the release of a large quantity of energy is called nuclear fusion.

photoshop1234 [79]

Answer:

$55,400

Explanation:

To determine the cash paid for salaries and wages during the year.

wages payable (beginning of the year) = $800

wages payable (end of the year) = $2600

Income statement on wages and salaries for the year = $57,200

cash paid for Salaries and Wages during the year = (Salaries and Wages Expense + wages payable at the beginning of the year) - wages payable at the end of the year

$(57,200 + 800) - $2600

$(58000-2600)

= $55,400
