Answer:
During their childhood, kids learn about the world that surrounds them when going through 3 different phases regarding their body parts, and taking contact with their family and school; when puberty strikes, the learning shifts towards the teen's peer group and their chosen role models to create new patterns in behaviour and find themselves (adolescence). Once the individual enters adulthood and establish his/her personality, can form strong and intimate relationships with friends and romantic partners (transitional adulthood). When reaching the middle years, the person needs to contribute to society in some way to feel productive, like raising children or helping his/her community. Finally, during the older years, humans tend to reflect on their lives and accomplishments to develop a sense of either integrity or despair.
Answer:
The correct answer is providing structure, regulating cell processes and creating movement.
Proteins are large molecules consisting of one or more polypeptide chains. They perform many important functions in the body such as:
- Structural base: they are the building blocks of the cell.
- Movement: They help in locomotion of a cell. For example, actin and myosin present in muscle cells.
- Hormones: Many hormones are protein in nature and help in the control and coordination of the body. For example, insulin and growth hormones are protein in nature.
- Enzymes: Most of the enzymes are protein in nature. Enzymes are biological catalysts which regulate the biochemical reactions taking place in an organism.
- Defense: Antibodies are protein in nature.
- Transport: Proteins form channels across the plasma membrane which facilitate the transport of molecules across the membrane.
In contrast, DNA acts as the genetic material which forms the blueprints of an organism as well as the bases of heredity. They are transcribed into different types of RNA which together synthesize the proteins.
