Murrr4er [49]

Answer:

Monomer: 2 - Amino acid

                 3 -Nucleotide

Polymer: 1 - Cellulose

               3 - Nucleic acids

Example: 1 - Carbohydrates

               2 -  Collagen

Function 1: Carbohydrates are a source of energy in the body.

Function 2: Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

Function 3: DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information

Explanation:

Monomers are single molecules that can bond with identical molecules to form polymers.

1. Glucose can combine with other glucose molecules to form starch or cellulose which results in formation of carbohydrates.

Carbohydrates are a source of energy in the body.

2. Amino acids can combine with other amino acids to form a protein chain which results in formation of collagen

Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

3. Nucleotides can combine to form nucleic acids resulting in formation of enzymes.

DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information

Sergeu [11.5K]

Answer:

A. = Shale

B = Granite

C = Sandstone

D = Limestone

Explanation:

Based on the weathering patterns, the rock type shown in each photo can be concluded to be as

A. = Shale: this is a form.of sedimentary rocks. It is formed from finely textured materials. Such as clay, quartz, and calcite minerals

B = Granite: this is derived from igneous rock. It has coarse texture features.

C = Sandstone: it is formed by a sand-sized grain of natural earth materials that form together

D = Limestone: it is also a form of sedimentary rock. It contains a large quantity of calcium carbonate it is formed from materials such as ancient corals and skeleton.
