This system gives the body shape and support.
- A.
Muscular System
- B.
Nervous System
- C.
Skeletal System
- D.
Circulatory System
Correct Answer
C. Skeletal SystemExplanation
The skeletal system is responsible for giving the body shape and support. It provides structural support to the body, allowing us to stand upright and move. The bones in the skeletal system also protect vital organs and provide a framework for muscles to attach to, allowing movement. Additionally, the skeletal system produces red and white blood cells, stores minerals, and helps regulate calcium levels in the body. Overall, the skeletal system plays a crucial role in maintaining the body's shape and providing support for its various functions.Rate this question:

This tissue connects one bone to another.
- A.
Tendon
- B.
Muscle
- C.
Cartilage
- D.
Ligament
Correct Answer
D. LigamentExplanation
Ligaments are connective tissues that join one bone to another. They provide stability and support to the joints by preventing excessive movement and maintaining the proper alignment of bones. Unlike tendons that connect muscles to bones, ligaments primarily function to hold bones together and allow controlled movement. Cartilage, on the other hand, is a flexible connective tissue that covers the ends of bones and acts as a cushion, while muscles are responsible for generating force and movement in the body. Therefore, the correct answer is ligament.Rate this question:

These muscles control involuntary movements like breathing, digestion, etc.
- A.
Smooth Muscle
- B.
Cardiac Muscle
- C.
Skeletal Muscle
- D.
Fascial Muscle
Correct Answer
A. Smooth MuscleExplanation
Smooth muscles are responsible for controlling involuntary movements in the body, such as the contraction and relaxation of organs like the stomach, intestines, and blood vessels. These muscles are found in the walls of various organs and structures and are characterized by their smooth appearance under a microscope. Unlike skeletal muscles, which are under voluntary control, smooth muscles work automatically and are not consciously regulated. Therefore, smooth muscle is the correct answer as it accurately describes the muscles that control involuntary movements like breathing and digestion.Rate this question:

The brain center of a cell.
- A.
Cell Membrane
- B.
Cytoplasm
- C.
Nucleus
- D.
DNA
Correct Answer
C. NucleusExplanation
The nucleus is the brain center of a cell. It is a membrane-bound organelle that contains the cell's genetic material, DNA. The nucleus controls all the activities of the cell and is responsible for storing and transmitting genetic information. It regulates gene expression, cell division, and the synthesis of proteins. Without a nucleus, a cell would not be able to function properly or carry out essential processes. Therefore, the nucleus plays a crucial role in the overall functioning and survival of a cell.Rate this question:

Cartilage is replaced by bone through a process called:
- A.
Ossification
- B.
Calcification
- C.
Osmosis
- D.
Cancellous Formation
Correct Answer
A. OssificationExplanation
Ossification is the correct answer because it is the process by which cartilage is replaced by bone. During ossification, new bone tissue is formed, and the cartilage is gradually replaced by this new bone tissue. This process is essential for the development and growth of bones in the body. Calcification refers to the deposition of calcium salts in tissues, and while it is involved in the formation of bone, it is not the specific process by which cartilage is replaced. Osmosis is the movement of water molecules across a semipermeable membrane, and it is not directly related to the replacement of cartilage by bone. Cancellous formation refers to the formation of cancellous bone, which is a spongy type of bone, but it does not specifically describe the process of cartilage replacement.Rate this question:
