The two essential functions performed by the vascular system, namely the delivery of resources (water, essential mineral nutrients, sugars and amino acids) to the various plant organs and provision of mechanical support are next discussed.
What is the function of a vascular system?
The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.
What does the vascular system do in plants ?
The circulatory system transports blood around the body. The vascular system has two parts. Xylem transports water and minerals up, and phloem transports sugar down and to all the cells of the plant.

Explanation:
Answer:
The correct answers are: b) "An amyloid fibril is stabilized by hydrophobic interactions between aromatic residues", c) "Soluble proteins that misfold and form amyloid fibrils become insoluble", and d) "Because most newly synthesized proteins fold correctly, the accumulation of misfolded proteins (or fragments) tends to occur slowly, thus explaining the slow onset of disease".
Explanation:
Amyloid fibrils are protein aggregates that can cause pathological conditions, for instance, they are found in brain tissue in people with Alzheimer disease. This disease, and other relates diseases, have a slow onset because most newly synthesized proteins fold correctly and the protein aggregates are made up misfolded proteins. This newly synthesized proteins are soluble, but once the proteins are misfolded, they form amyloid fibrils that are insoluble. The amyloid fibrils are stabilized by hydrophobic interactions between aromatic residues, which are formed within the complex of insoluble misfolded proteins.

Explanation:
Answer:
Vitamin C is an antioxidant and essential nutrient that has many functions. For example, it helps produce collagen, reduce oxidative stress, and enhance wound healing. Fresh fruits and vegetables are good sources of vitamin C.
Vitamin C, also known as ascorbic acid, has several important functions. These include: helping to protect cells and keeping them healthy. maintaining healthy skin, blood vessels, bones and cartilage.
People who get little or no vitamin C (below about 10 mg per day) for many weeks can get scurvy. Scurvy causes fatigue, inflammation of the gums, small red or purple spots on the skin, joint pain, poor wound healing, and corkscrew hairs
