2. When diffusion has reached equilibrium, we say that
madam [21]

Answer:

See Below.

Explanation:

The key word here is <em>net. </em>The net movement has reached zero when a system is in equilibrium but there are still motion's going back and forth due to statistics and just random brownian motion.

Think of it this way, if there are 100 people walking forwards in a crowd but 2 are moving against the crowd, the net movement is still forwards because the bulk of people are going in that direction. However, there are still 2 people moving against.

Same here, if we are talking about a diffusion, let's say in the case of osmosis, if most of the solute is moving across a membrane then we'd say its net direction is that way but that doesn't mean that there aren't processes happening in the other direction. Water molecules in osmosis mostly diffuse, chemically speaking (because you can say this biologically in a different way), from the probability of water molecules colliding with each other and passing the membrane so even if there is a net movement in a certain way their random motion can make them go to the other side just as well. If the fact that motion stops at equilibrium were the case a lot of systems, both chemical and biological, would not exist as we know it.

Think net = bulk <u>NOT</u> <em>total</em> or <em>entire.</em>

Kisachek [45]

Answer:

C. Cheaper than producing electricity from coal oil gas.

Explanation:

Nuclear plants and energy has been proven to be cheaper than most, Low fuel costs have from the outset given nuclear energy an advantage compared with coal and gas-fired plants. Uranium, however, has to be processed, enriched and fabricated into fuel elements, accounting for about half of the total fuel cost.

Mr. Whiskers, a cat that loves to eat, has a mass of 39 kg. Mr. Whiskers sees a mouse and decides to chase it, and accelerate at
Sphinxa [80]

Answer:

Force = 78 N

Explanation:

Given data:

Mass = 39 Kg

Acceleration = 2 m/s²

Force generate = ?

Solution:

Formula:

F = ma

F = force

m = mass

a = acceleration

Now we will put the values.

F = 39 Kg × 2 m/s²

F = 78 Kg.m/s²

Kg.m/s² = N

F = 78 N

Synthesis of an inducible enzyme requires Select one:
Leona [35]

Answer: B

Explanation:

Synthesis of an inducible enzyme requires the substrate bound to repressor.

In the synthesis of a specific inducible enzymes, a substrate on which the enzyme acts must bind to the repressor that prevents the synthesis of the inducible enzyme. Example of an inducible enzyme is β-galactosidase in Escherichia coli that degrades lactose and galactose.

The synthesis of β-galactosidase is regulated by a repressor protein, that binds to the region of deoxyribonucleic acid (DNA) that codes for the synthesis of β-galactosidase. If lactose or galactose (substrate) is present, it acts as an inducer which induce the repressor protein from binding to DNA. Hence the enzyme is synthesized
