Answer:A) proteins are useful as enzymes, hormones etc.
B) the building block of protein are amino acids
Further explanation below
Explanation: A) proteins are polymers formed by several chains of amino acids. They occur in living tissue and form 50 -- 60% of the total dry mass of the living cell. Proteins found in the membrane are used as structural integrity. Some proteins are catalytic in nature and are such are used as enzymes. They also occur as hormones. Proteins help in the transport of substances across the cell membrane, when they are found in the cell membrane.
B) the building block of protein are amino acids. They undergo condensation reaction to form proteins.
The structure of amino acid is in the attached photo.
R = the group that determine the name of the amino acid. It may be a hydrogen atom,an alkyl, an aryl, or carboxyl group.
H2N = the amino group
COOH = the carboxyl group
C = the alpha central carbon to which other groups are attached.
1) Eubacteria.

Answer:
Cohesion is an attractive force between same kind of molecules while adhesive force exists between different kinds of molecules. When water moves inside vascular tissue they contain cell sap. It is these two forces which keep materials in cells and water can easily move them to different parts where they are necessary.
Answer:
Elastic Fibre
Explanation:
Due to its ability to stretch and return to it's Normal size. It is one of the three main types
Explanation:
An organisms <u>genes </u>are located on threadlike structures called chromosomes.
Genes are a set of coded instructions in the form of DNA, which are crucial to cell regulation- these enable protein synthesis.
Further Explanation:
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and carry out protein synthesis.
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
