marysya [2.9K]

Answer:

(d) None of the above

Explanation:

The pH of your stomach must be highly acidic, because the optimum pH for pepsin, the chief stomach enzyme, is 1.5.

(a) and (b) are wrong, because both conditions are basic.

(c) is wrong, because pH 7 is neutral.

Le châtelier's principle states that if a stress is applied to a system in dynamic equilibrium, the system _____ to relieve the
iris [78.8K]

Answer:

Le châtelier's principle states that if a stress is applied to a system in dynamic equilibrium, the system changes to relieve the stress.

Explanation:

This principle shows that when we change a system in equilibrium, it will seek to acquire a new state that nullifies this disturbance. Thus, there is a displacement of equilibrium, that is, a search for a new equilibrium situation, favoring one of the senses of the reaction. If it favors the direct reaction, with formation of more product, we say that the equilibrium has shifted to the right. However, it is said that it shifted to the left if the reverse reaction was favored, with formation of reagents.

When a gummy bear shrinks, is that considered hypertonic or hypotonic?
raketka [301]

Answer:

Hypertonic

Explanation:

In hyper-tonic solutions, the cell will shrink and crenate. The mass and volume of a gummy bear that is placed in a salt solution will decrease due to the effect of osmosis. When placed in water, a hypo-tonic solution, the gummy bear will expand in size and volume due to the water entering it.

Content practice a acceleration lesson 3 answers
sdas [7]

Acceleration is defined as the rate of change in the speed of a moving body or vehicle typically.

<u>Explanation:</u>

In the branch of mechanics, the aspect of acceleration is considered to be a property of the vector. And acceleration always occurs in a specific positive direction.

The formula for determining acceleration is change in the rate of velocity over a specific time, and is therefore measured as the ratio of delta velocity by delta time unit.

  \text {acceleration}=\frac{\text {velocity}}{\text {time}}=\frac{\left(\frac{\text {distance}}{\text {time}}\right)}{\text {time}}=\frac{\text {distance}}{\text {time}^{2}}\left(\mathrm{m} / \mathrm{s}^{2}\right)

The unit of acceleration is distance per time unit squared or m / second squared.
