Explanation:
All animals are eukaryotic, multicellular organisms, and almost all animals have specialized tissues. Most animals are motile, at least during certain life stages. Animals require a source of food to grow and develop. All animals are heterotrophic, ingesting living or dead organic matter.
Answer:
A) A mutation in a single gene can result in a defective protein.
Explanation:
This hypothesis states that one gene codes for one protein-enzyme, so consequently, if mutation occurs in that gene, the enzyme will not work properly. This hypothesis was very important for the fundamental discoveries of molecular biology, but it is oversimplified meaning that relationship between genes and proteins is much more complex.
Compound microscope is commonly used in the schools and colleges. It has two lenses, the objective lens and the ocular lens. It provides a magnification of 1500X. Eyepiece lens is of 10X or 15X power. It is used to observe bacterial, protozoa, various cells, etc.
Dissecting Microscope It is also called stereo microscope. Its magnification power is less than the other microscope. It gives a 3 dimensional picture. Due to the low magnifying power they are used to observe little bigger objects than other microscopes. They are used in the surgeries, dissection, forensic science etc.
