Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Explanation:
Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.
The correct answer is B!
Why is this?
A mineral is a naturally occurring, inorganic solid with a definite crystalline structure and chemical composition. All minerals contain one or more elements, which are pure substances that cannot be broken down into simpler substances by chemical means.
Answer:
Please find the main difference in details between these two microscopes below
Explanation:
Compound microscopes and dissecting microscopes are two types of light microscopes. This means that both types of microscope uses light as a source of view. However, they are used for different purposes despite this similarity.
- The compound microscope is used to view the internal features of a small specimen by looking through it. This is due to the high magnifying power of its objective lenses (40x - 1000x).
- On the other hand, dissecting microscopes are used only to view the surface of a large specimen owing to its low magnifying power. It can be used to view a three dimensional object.
Perhaps the study of chemical reactions is not a central theme of biology, but of chemistry.
