Answer:
Oxidize organic compounds AND use organic compounds as terminal electron acceptors. (Ans. E)
Explanation:
Anaerobes are the organism that does not require oxygen for their growth. The anaerobes are subdivided into three main classes:
1) Obligate anaerobes: These organisms use anaerobic metabolism to grow and killed in the presence of oxygen. Obligate anaerobe examples are Clostridium and Propionibacterium.
2) Facultative anaerobes: These organisms prefer to grow using aerobic metabolism processes and switch to anaerobic metabolism in the absence of oxygen. An example of facultative anaerobic bacteria is Lactobacillus.
3) Aerotolerent anaerobes: These organisms use anaerobic metabolism to grow and can survive in both conditions (oxygen and oxygen-free environment).
Anaerobic bacteria, oxidize organic compounds rather than oxygen & use organic compounds as terminal electron acceptors. Anaerobic bacteria release hydrogen sulfide gas as they decompose algae in the water. This process is also known as Anaerobic Respiration, in which formation of ATP without oxygen.
Explanation:
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.
“20.2 Graphical representation of vectors (ESAGK)
Vectors are drawn as arrows. An arrow has both a magnitude (how long it is) and a direction (the direction in which it points). The starting point of a vector is known as the tail and the end point is known as the head.”
