Cellulose belongs to carbohydrates.
Cellulose is classified as a carbohydrate, a polysaccharide, as they are formed of the glucose monomers chain. It is the prime component in the walls of the cells of plants, assisting the plants to remain upright and stiff. Humans cannot digest cellulose due to the absence of cellulase, however, it is essential in the diet as fiber.
However, the animals like sheep, cows, and horses can digest cellulose that is why they can acquire nutrients and energy they require from the grass.
Answer:
A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains
Explanation:
Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.
Nucleic acids tend to form linear chains from the monomers called nucleotides. Nucleotides have three components: nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.
Hence, the correct option is "A
. proteins can take a variety of shapes, and nucleic acids tend to form linear chains".
The right and the left halves of the cerebrum are called CEREBRAL HEMISPHERE. There are two types of cerebral hemisphere; the left cerebral hemisphere and the right cerebral hemisphere. The left cerebral hemisphere controls the right side of the body while the right cerebral controls the left side of the body. The left cerebral hemisphere is responsible for the controls of tasks that has to do with reasoning and logic, it is the seat of intellect while the right hemisphere is responsible for tasks that has to do with creativity, imagination and intuition.
