If the two groups involved in an experiment are not equivalent,
it cannot be ascertained that the independent variable caused the results.
The experimental group, also known as the treatment group, receives the treatment whose effect the researchers wish to study, while the control group does not. They should be identical in all other respects. We know that if we two groups participate in any kind of experiment, we know that the study of that experiment is not equivalent, nor that the experiment cannot be determined with certainty in which independent variable produces, arises, or causes results and outcomes. . Therefore, this option is true.

They have to describe the characteristics of life hope this helps.
Everyone’s body is made of the same basic stuff. All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms. Water makes up about two thirds of the weight of cells.
Cells are very small; most cells can only be seen through a microscope. Cells are the smallest living units that are capable of reproducing themselves. Each cell in your body was made from an already existing cell. All plants and animals are made up of cells. In this article, we will talk about the cells that make up You.
pre All the parts of your body are made up of cells. There is no such thing as a typical cell. Your body has many different kinds of cells. Though they might look different under a microscope, most cells have chemical and structural features in common. In humans, there are about 200 different types of cells, and within these cells there are about 20 different types of structures or organelles.
Answer:
Circular and Radial muscles.
Explanation:
The pupilarry response is the variation of pupil's size due to a variety of causes (exposure to light, sexual stimulation, drugs) and it consists of two movements, constriction and dilation.
<em>The constrict response occurs thanks to the circular muscle and the dilations is triggered by the radial muscle, both of them are smooth muscle.</em>

Answer:
<em>Basically enzymes are biological catalysts. They speed up chemical reactions. Enzymes are required mostly of the chemical reactions that happen in organisms . These reactions happen in the breakdown of chemical molecules. That is what we see in our digestive system .</em>
