Answer: The means for transmission of disease-causing microorganism is provided by the direct or indirect contact.
Microorganisms can cause disease only once they are transferred to the body. The disease causing microorganisms are termed as pathogens which are transmitted by several ways such as from skin to skin, by nuclei droplets, through blood and body fluids or via air. In vector transmissions the disease is carried by the parasitic insects via animals, air borne transmission occurs when microorganisms move through air or the dust particles, droplet transmission occurs by coughing, sneezing or talking by the person who is infected while indirect transmission occurs by physical contact or by touching contaminated objects.
Answer:
True
Explanation:
This statement is true, catabolism is a process where molecules that have a high content of energy in its bonds, are broken down to use the energy, on the other hand, we have anabolism, which is the building of molecules, and it requires energy to do this. The combination of these processes is called metabolism. In anabolism, and catabolism the energy, which is used for the function in the body, is in the molecules' bonds.
The most common molecule that has a high content of energy in its bond is ATP (adenosine triphosphate).
Because for each glucose molecule there are two pyruvic acid molecules entering the system, two ATP molecules are formed<span>. Also </span>during the Krebs cycle<span>, the two carbon atoms of acetyl-CoA are </span>released<span>, and each forms a carbon dioxide molecule.</span>
