N-type semiconductors have an excess of electrons due to the addition of donor impurities.

Doping silicon with phosphorus creates an n-type semiconductor due to the addition of extra electrons.

Molecular solids are composed of molecules held together by van der Waals forces and have a definite melting point.

Ionic solids have a definite melting point and are typically hard and brittle due to the strong ionic bonds between the ions.

Crystalline solids have a definite melting point due to their ordered structure, unlike amorphous solids which melt over a range of temperatures.

Raoult's Law applies most accurately to ideal solutions, where interactions between different molecules are similar to those in pure substances.

Muscle tissue is responsible for movement in animals.

Muscle tissue is responsible for the movement of the body.

Lymphocytes are a type of white blood cell that plays a key role in the immune response.

Vitamin D can be synthesized by the body when the skin is exposed to sunlight.

A deficiency in Vitamin A can lead to night blindness, as it is crucial for maintaining healthy vision.

A deficiency in Vitamin C can lead to scurvy, characterized by symptoms such as bleeding gums and fatigue.

Scurvy is caused by a deficiency of Vitamin C.

Vitamin B1 (thiamine) acts as a coenzyme in carbohydrate metabolism.

Vitamin E is known for its antioxidant properties, helping to protect cells from oxidative damage.

Vitamin B1 is also known as thiamine and is important for carbohydrate metabolism and nerve function.

Ascorbic acid is the chemical name for Vitamin C, which is important for immune function.

Vitamin B12 is crucial for the formation of red blood cells and the maintenance of the nervous system.

Vitamin K is essential for the synthesis of proteins required for blood clotting.

Vitamin D is essential for the absorption of calcium, helping to maintain bone health.

Vitamin B5, also known as pantothenic acid, is essential for the synthesis of coenzyme A, which is important in fatty acid metabolism.

Vitamin C is crucial for the synthesis of collagen, a key structural protein in the body.

Vitamin A is essential for the synthesis of retinal, which is important for vision.

Vitamin K is essential for the synthesis of proteins required for blood clotting.

Vitamin B6 is important for amino acid metabolism and the synthesis of neurotransmitters.

Vitamins B1, B2, and B6 all play important roles in the metabolism of carbohydrates and amino acids.

Vitamin B1, also known as thiamine, is important for carbohydrate metabolism.

Vitamin B5, also known as pantothenic acid, is important for the metabolism of fatty acids.

Vitamin A is crucial for vision, particularly in low-light conditions, and also plays a role in immune function.

Vitamin K is essential for the synthesis of proteins required for blood clotting.
