The immune system is spread throughout the body and involves many types of cells, organs, proteins, and tissues. Crucially, it can distinguish our tissue from foreign tissue — self from non-self. Dead and faulty cells are also recognized and cleared away by the immune system.
If the immune system encounters a pathogen, for instance, a bacterium, virus, or parasite, it mounts a so-called immune response. Later, we will explain how this works, but first, we will introduce some of the main characters in the immune system.
Roles of protein:
Hormone production
Enzymes- proteins bind to molecules to speed chemical reactions
Immune Function/immunity- anti bodies that bind to pathogens and inhabit their activities
Energy- protein is broken down to amino acids during digestion
Transporting oxygen
proteins can also blood clot, contract muscles, and they make up muscles,hair,and nails
<u>Answer</u>: Appear to function in similar ways across diverse groups of organisms.
<u>Explanation</u>:
- The <em>hox</em> genes are a subset of homeotic genes.
- The function of the hox genes is to control the development of the body plan of an individual during the embryonic stage.
- Thus, the basic body form of an organism is laid down with the help of these genes.
- <em>These genes are present in many different species from fruit fly to mice to humans</em>.
- The reason that they are present in different organisms is that there was a common ancestor that possessed the hox gene cluster and then the genes were passed on to different vertebrates. However, the slight changes that have occurred in these genes are due to duplication events.
