Answer:
In this lab, a visual representation of the process of DNA profiling was created by the process of gel electrophoresis. This process begins by using a restriction enzyme to cut the DNA into smaller fragments. The DNA fragments are placed in the holes of gel called wells. The gel is placed near the negative electrode. The DNA fragments travel toward the positive electrode because the DNA fragments are attracted to that side. The small molecules moved quickly through the gel and the large molecules moved slowly, creating a pattern of bands that can by analyzed.
Explanation:
DNA profiling can be described as a forensic technique which is using for comparing the DNA of different suspects with the DNA found at the crime site.
Gel electrophoresis can be described as a process through which different samples of DNA are separated based on their size and charge to mass ratio. The fragments of the DNA run on an agarose gel where they run from the negative terminal to the positive terminal depending on their size. The smaller molecules having a smaller mass will move faster than the larger molecules.
Answer:
animal like protists are called protozoa
Explanation:
this is because of the presence of single-cell, characteristics such as inability to produce food for themselves
Cells are the basic unit of life, which carries several cell organelles specialized in their functions. The cells function similarly as the factory would work.
Thus, the cell works similarly to that of the factory, in which each organelle is developed to carry out different functions.

Chemical breakdown processes in cells directly involve enzymes, which facilitate chemical reactions by lowering activation energy. Examples include cellular respiration and digestion.
All chemical breakdown processes in cells directly involve enzymes, which are specialized proteins that facilitate chemical reactions. Enzymes work by lowering the activation energy required for a reaction to occur, allowing chemical breakdown to happen more efficiently. Some common examples of chemical breakdown processes in cells include cellular respiration, where glucose is broken down to release energy, and digestion, where food molecules are broken down into smaller units for absorption.

Chemical breakdown processes in cells directly involve catabolic reactions, which form part of the cell's metabolism. Complex molecules are broken down into simpler ones, releasing energy. An understanding of this process is vital for understanding how cells, and biological systems more generally, function.
All chemical breakdown processes in cells directly involve a type of biochemical reaction known as catabolism. This is part of the cell's metabolism, which includes all chemical reactions that occur within the cell. Catabolism is the process through which complex molecules are broken down into simpler ones, with an accompanying release of energy.
For example, complex carbohydrates from food are broken down into simpler glucose units through catabolism. Furthermore, catabolic reactions also involve the breakdown of Adenosine triphosphate (ATP), the primary energy currency of cells. The energy released from catabolic processes drives different cellular activities and reactions.
The balance between catabolic and anabolic (building up) processes allows cells to harvest and efficiently use the energy necessary for their functioning. Therefore, energy is central to these cellular chemical processes. To understand any biological system, including cells and their biochemistry, it is crucial to understand how energy flows and is utilized within these systems.
