Answer:
Collagen fibers
Explanation:
Cartilage is the connective tissue found in the mammalian group of animals and is composed of the collagen fibre made by the chondrocytes which occur at the scattered sites.
The fibrocartilage is one of the types of cartilage present in the intervertebral disks and helps provide the tensile strength and help absorb the shock in the spine.
The extracellular matrix of fibrocartilage is enriched with the collagen fibres which provides toughness and great tensile strength to the cartilage.
Thus, Collagen fibres are the correct answer.
The correct answer is (c) They show which part of the brain are involved in specific activities.
The functional magnetic resonance imaging is used to measure the activity of brain by the detecting the change in the blood flow. This is done because the cerebral blood flow is associated with the neuronal activation. The functional area of brain has a higher blood flow that can be observed in functional MRI. The commercial application of functional magnetic resonance imaging is used in lie detectors. This technique is also used in research world and in some clinical trails. Physicians use this technique to see how risky a brain surgery can be. It is also used to learn how a normal, diseased, or injured brain functions.
The correct answer is the organ.
The multicellular species are formed of various parts, which are required for survival. These parts are differentiated into the levels of the organization. There are five different levels, which are named as cells, tissue, organs, organ systems, and organisms.
When two or more layers of tissue function together, they produce an organ. All the animals comprise vital organs, without which they cannot survive. These include the kidneys, liver, lungs, brain, and heart.
