Answer:
These cleaning products break apart the capsules of the viruses causing them to no longer be capable of infecting an individual.
Explanation:
Bleach oxidises organic molecules. This causes proteins to become denatured, or lose their shape. The viral capsule containing the DNA is a coat made up of proteins that is required for the virus to become infectious. Therefore, following bleach treatment, the viral protein capsule become oxidised, cause them to loses their shape, meaning the virus can no longer infect individuals.
Answer:
C. Slide A, plant cells; Slide B, animal cells
Explanation:
The slide A has some organelles that are unique to plant cells, and are mostly found in plant cells. Organelles such as a cell wall and chloroplasts are unique features of plant cells. They are normally absent in animal cells.
Therefore, slide A, which has these cell organelles can be rightly labelled as "plant cells", while side B, which has these organelles missing, can be labelled as "animal cells".
Lipids contain more energy that carbohydrates because they contain more carbon to hydrogen bonds to release energy when broken.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Answer:
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA
