Answers

Answer:

The liquid levels in the solution will become more dilute (have more water) due to Osmosis.

Explanation:

This is because Osmosis moves down a concentration gradient so the water outside the solution will become more concentrated and the solution will become more dilute.

4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!

Answers

Answer:

The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.

For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.

Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.

Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.

However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.

Explanation:

. B.9(C) For an enzyme to be able to catalyze a reaction, the active site must---- *
1 point
be occupied by an inhibitor
increase the activation energy level
have a complementary shape to the substrate
cause the enzyme to be destroyed in the reaction
go keilani

Answers

A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.

The correct answer is:

Option C. have a complementary shape to the substrate.

This can be explained as:

If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.

Activation energy is the minimum amount of energy needed for the reaction.

If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.

Therefore, the active site should have a complementary shape to the substrate.

In the diagram of the human digestive system, what organ is labelled 5?

Answers

Answer:

The large intestine

Explanation:

The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.

As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.

Hopefully that was helpful! :)
