We know that oil floats on water and do not mix
<span>
What happens to the oil when you first pour it in? It flows into the water, but then seperates.
Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same
What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans
Use a spoon to stir the oil for 30 seconds.
Answer the following questions:
What natural action stirs the real ocean? ocean currents caused by wind and the earth's roation
What happened to the oil? went back to the top
Even if you can’t see it, is all the oil still in your ocean? yes
Which animals in the ocean become affected after wave and current
action causes some of the oil to settle to the bottom, or be absorbed
into the water? bottom-feeders
Add a splash of dish detergent to the mixture and stir.
Answer the following questions:
What happened to the oil? it mixed with the water Is it all still in the ocean? yes
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done? to bond the oil to the detergent and the detergent to the water. so they can grab all the oil
What might be a negative effect of dumping the soap?</span> soap has chemicals that could upset the ballance of the ecosystem and kil some animals/plants
In test tube B i.e., egg, albumin, pepsin and HCl the digestion of protein will occur as HCl will breakdown protein into simple molecules.
- Pepsin will be activated by HCl to break down proteins into their simpler constituents.
- Some enzymes, like pepsin in this instance, are activated by HCl in a catalytic manner.
- Gastric juice is a mixture of lipase, other digestive enzymes, and the least amount of diluted hydrochloric acid required for digestion.
- Pepsin, a digestive enzyme found in the stomach that aids in the breakdown of dietary proteins, is also present in this gastric fluid.
- Foods like milk, beef, and other dairy products are high in protein, which is broken down into smaller molecules for digestion.
- The pepsin is activated by the HCl in gastric juice. The protein intake is then catalyzed by the enzyme pepsin, which causes it to be broken down into smaller peptide molecules.

A student sets up an experiment to study the role of enzymes in digestion of food. In test tube A, he added egg albumin and pepsin. In test tube B, he added egg albumin, pepsin and HCl. In which test tube, the digestion of protein will occur? *
Test tube A as pepsin will breakdown into simple molecules.
Test tube B as HCl will breakdown protein into simple molecules.
Test tubes A as pepsin will breakdown protein into simple molecules.
Test tube B as HCl will activate pepsin for breakdown of protein into simple molecules.
Answer:
198 organisms after the increase
Answer:
the decomposers do what their name says... they decompose
Explanation:
they decompose the dead animals and plants and turn them into nutrients that helps the plants grow
Because it is meant to be like that for animals , us humans dont need all the stuff that animals do.
