the process by which the structure of a biological community evolves over time. Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. Secondary succession occurs in areas where a community that previously existed has been removed; it is typified by smaller-scale disturbances that do not eliminate all life and nutrients from the environment.
The adipose tissue is the particular type of tissue that is abundant with enzymes that engage in thermogenesis and do not particularly accomplish any other work. These enzymes are only stimulated through locomation and intentional movement of the muscles and can be classified into three:
a. Exercise-associated thermogenesis (EAT)
b. Non-exercise activity thermogenesis (NEAT)
c. Diet-induced thermogenesist (DIT)
Answer:
The genetic code only consists of 4 letters of A T C and G. That means it is a VERY simple language. Combinations of three of these letters (codons) are translated into functional information in the form of amino acids. Each three letters = one amino acid.
Although the code seems simple, the information that can be derived from it is highly complex, making an entire organisms.
Take for example a simple 4 letter sequence of letters. ACTG, AGTC, AATG, etc. There are 256 potential combinations, just in a sequence of 4. Imagine in humans where there are THREE BILLION letters! The possible combinations are essentially endless.
I believe its allostatic load which is the wear and tear on the body that accumulates when we are under a lot of stress
