Cancer cells divide endlessly
It’s characteristic is the need for energy
Answer:
See the answer below
Explanation:
<em>Obligate anaerobes are microbes that can only survive in oxygen-deficient environments. They are killed by the normal atmospheric level of oxygen and will only thrive in environments whose oxygen levels are lower than that of normal atmospheric level. </em>
Obligate bacteria such as <em>Clostridium botulinum </em>obtain their energy through <u>anaerobic respiration processes such as fermentation and anaerobic respiration.</u> During this process of fermentation, the lactic acid pathway is mostly used but other fermentation pathways such as propionic acid, mixed acid, acetogenesis, and methanogenesis pathways can be used.
Answer:Regulation of Digestive Fluids.
Explanation: The gastric phase of digestive secretion happens after you swallow food, when protein stimulates the release of stomach acid and digestive enzymes.
Answer:
At low Ts= Hopanoids increase membrane fluidity
At higher Ts= Hopanoids reduce the membrane fluidity
Explanation:
Bacterial membranes lack cholesterol but have hopanoids. Hopanoids are synthesized from the same precursor as the steroid. The hopanoids also have five fused ring structures like that of cholesterol. The amphipathic nature of hopanoids allows them to maintain the membrane fluidity under low and higher temperature conditions.
When the temperatures are higher, the hopanoids serve to reduce the membrane fluidity by their ability to interact with polar heads and non-polar tails of the membrane phospholipids. At lower temperatures, hopanoids insert themselves between the non-polar tails of phospholipids to increase the membrane fluidity.
