What does a scientist observe in a chemical's reaction rate? the speed at which the reactants change to products over a given ti
kvasek [131]

Answer:

The speed at which the reactants change to products over a given time.

Explanation:

A chemical's <u>reaction rate</u><u> is the change in the concentration of a reactant or a product with time (in moles per second)</u>.

Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:

reactants → products

Therefore,<u> the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.</u>

According to the temperature and other parameters, the reaction rate can increase or decrease.

Power stroke (myosin head bends) coupled with the release of ADP and phosphate, ATP hydrolyzed to ADP and Phosphate and the Myos
svetlana [45]

Answer:

Power stroke (myosin head bends) coupled with the release of ADP and phosphate

Explanation:

Muscle contraction results from myosin heads adhering to actin and attracting it inwards. It uses ATP. Myosin adhers to actin at a binding site of its globular actin protein and adheres at another binding site for ATP (hydrolyzed ATP to ADP, Pi  and energy)

ATP binding prompts myosin to detach from actin, ATP is changed to ADP and inorganic phosphate, Pi by ATPase. The energy formed at this process orientates myosin head to a “cocked” direction.

The myosin head goes in the direction of the M line, holding the actin with it in the process causing the filaments to orientate nearly 10 nm in the direction of the M line--- power stroke (force is produced), the sarcomere reduces in length and the muscle contracts.

Note: The power stroke is seen when ADP and phosphate disattaches itself from the myosin head.

At the terminal point of the power stroke, the myosin head as low-energy, followed by ADP release.

The attached image shows the cross-bridge muscle contraction cycle, which is activated  by Ca2+ sticking to the actin active site. And how actin moves in relation to myosin.

The illegal poaching,trading, transporting, buying or selling something is called what?
LUCKY_DIMON [66]

<u>The illegal wildlife trade </u>or <u>wildlife trafficking</u> is the commercial process that involves the trade of non-domestic species (animals or plants), or in some cases certain parts of individuals. These species are rare and endangered and thus this practice is harmful and represents an increasing dangers of extinction.

This practice is highly illegal, but unfortunately, at the same time, due to the rarity of the species highly profitable. Efforts are made globally to stop this practice and to avoid the extinction of many endangered species.
