Answer:
B. found in every living thing
Explanation:
Skin is the first line of defense mechanism of our immune system. It acts as a barrier for pathogenic and opportunistic microorganisms. However, skin itself has a microbiota that does not allow other microorganisms to invade or colonize. Any wound, cut or change in the pH of skin due to environmental conditions or any disease might lead to the entry of the opportunistic microorganisms inside the skin. This leads to several skin disorders such as dermatitis, eczema, cellulitis, warts, etc. Thus, it is extremely important to keep the skin hydrated and healthy to avoid any kind of microbial invasion.
Answer:
b- It is a spontaneous process.
Explanation:
Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously. There is no energy expenditure during passive transport because substances naturally move from the more concentrated to the less concentrated medium, ie in favor of the concentration gradient.
Substance transport occurs until concentrations inside and outside the cell are equalized.
According to this conceptualization we can conclude that the correct answer to your question is the letter B.
Answer:a hydrocarbon reacts with oxygen
Explanation:
About this much of the energy released from food molecules during catabolism is released as heat: adenosine triphosphate (ATP)
The Adenosine triphosphate (ATP) is the source of the energy for the use and the storage at the cellular level. The structure of the ATP is a nucleoside triphosphate, consisting of the nitrogenous base (adenine), and ribose sugar, and the three serially bonded phosphate groups
ATP is synthesized in the mitochondria is the primary energy source for the important biological functions, such as the muscle contraction, the nerve impulse transmission, and the protein synthesis
In general, the main energy source for the cellular metabolism is the glucose, which is the catabolized in the three subsequent processes—the glycolysis, tricarboxylic and acid cycle (TCA or Krebs
