Answer:
The correct answer would be the slide should be almost in focus when changing to higher magnifications.
A parfocal lens is a type of lens which stays in focus when focal length or magnification is changed.
Parfocal microscopes are those in which objectives remain in focus even when magnification is changed for example, when it is switched from 10x to 40x, the object or slide remains at the focus.
Chemical features like 3 dimensional structure and chemical bonding are responsible for diversity in biomolecules although they are made from simple monomers.
In the case of carbohydrates, both starch and glycogen are made up of glucose monomers yet they differ in the functions which they perform in our body. This difference is because of the chemical bonding and the 3 dimensional structure.
Similarly in protein biomolecules, amino acids act as the monomers but they differ in function due to their 3 dimensional structure. Nucleotides are the building blocks of both RNA and DNA. RNA and DNA perform different functions in the body. DNA stores ad transfers genetic information while RNA is responsible for directly coding for amino acids.

Answer:
cartilaginous joints
Explanation:
The joint system is formed by the joints, which can be defined as the joining region between two or more bones. All bones in the body except the hyoid bone are articulated with at least one other bone. There are several types of joints, among them, the cartilage joints, those that have cartilage between the bones. If this cartilage is hyaline, the joint is called synchondroses; if the cartilage is fibrous, the joint is called symphyses.
The joints are responsible for holding the bones together and allowing the skeleton to move.
