What kind of control like scientific?

A control group in an experiment is very important. It is the group in an experiment that is separated from the rest of the experiment that’s being tested with the independent variable. It’s important for many reasons. The main reason is because using a control group, you can see the difference that an independent variable makes on the experiment. If we didn’t have a control group, you wouldn’t know how the group that is being tested is any different after the experiment than it was before. The control group gives you something to base it off. The control group is the group that doesn’t change. For example, in an experiment, if we want to test a plant fertilizer, we would have a control group and the group being tested. We would give the control group just water and no fertilizer. The other group that we are testing, we would give the plant fertilizer to. After a certain period of time, if the control group plants grow slower than or not as well as the group using the fertilizer, we know that the fertilizer works, if the opposite is true than the fertilizer doesn’t work.

Hope that helps u!

Which equation is used to help form the combined gas law? mc009-1. Jpg mc009-2. Jpg mc009-3. Jpg mc009-4. Jpg.

Luba_88 [7]

The combined gas law equation has been $\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$ .

The combined gas law has been assigned to the ideal gas. It has been stating that ideal gas are having negligible inter-molecular attraction and collision resulting in the absence of pressure and volume from the particles.

In an ideal gas the equation has been given as:

$PV=nRT$

Where, P has been the pressure of the gas

V has been the volume of the gas

n has been the moles of the gas

R has been a constant

T has been the temperature of the gas

The combined gas law has been given as the change in the pressure, and volume for a gas. It has been given as:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

Inside the stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down proteins to amino acids.

✤ So, Fill the blank with proteins.

<h3>Explanation:-</h3>

Inside the stomach, the digestion of proteins starts due to the action of pepsin enzyme.
But this enzyme remains inactive and is activated by the Hydrochloric acid(HCl).
The Hydrochloric acid also helps in killing the germs and microbes which entered along with food.
The mucous lines the wall of stomach to protect it from the harm caused by HCl because HCl is a strong acid.
In stomach, The partial digestion of proteins occur and rest is digested in the small intestine by Trypsin(Pancreatic enzyme) and Intestinal juices.
