Answer:
Yes, dynamic equilibrium is present in the cell.
Explanation:
In dynamic equilibrium, the concentration of solute remain the same due to equal flowing of solutes inside and outside the cell so there is no change occurs inside the cell, the cell maintain same concentration of solutes both inside and outside the cell. Dynamic equilibrium is a type of equilibrium in which the reactants and products formed at the same rate and no change occurs inside the reaction. In the cell, homeostasis is responsible for maintaining equilibrium in the cell so no change occurs inside the cell.
Could you take a better picture? I can not read that.
There are choices for this question namely:
a. Oil and water
b. Salt and water
c. Brass (and alloy of copper and zinc)
d. Granite (a type of rock with multicolor spots)
The correct answers are
oil and water, and
granite. Heterogenous mixtures are mixtures wherein the solutes can still be identified from each other. Homogenous mixtures are mixtures wherein solutes are completely mixed and cannot be identified. In oil and water, one can identify which is the oil and which is the water. In granite, it is a mixture of different rocks and these different materials can be identified due to the presence of multicolored spots.
<u>Answer:</u>
The “wheelchair belt” mechanism is the most important mechanism to have on the wheel chair.
<u>Explanation:</u>
- As the patient have very poor control over his trunk so a belt will be perfect to prevent him from falling out of the wheelchair anytime.
