Answer:
pathogens
Explanation:
pathogens may occur in various way e.g spread from a person to person by directly body contact
The formula for aerobic respiration in animals can be shown by the equation below. A glucose molecule is broken down by enzymes in the presence of oxygen to make carbon dioxide, water, and ATPs. Carbon IV oxide is expelled by the lungs.
C₆H₁₂O₆ + 6O₂ --> 6CO₂ + 6H₂O + 38 ATP
This process occurs in two stages. Glycolysis (that does not require oxygen) occurs in the cytoplasm of cells. The products of the glucose breakdown in this stage is pyruvate, CO₂ and 2 net ATPs. The pyruvate is then converted to acetyl-CoA that enters the second stage called Citric/Krebs cycle. This second stage happens in the mitochondria. The products are CO₂, H₂O and 34 ATPs

Answer: The immune system
Explanation:
The immune system is a complex network of proteins and cells that defends the body against infection or any invasion. The human defense system in the body is actually made up of entire organs and vessel systems like the lymph vessels. The immune system is made up of organs that control the production and maturation of certain defense cells.
Initially, all living things are subjected to attack from disease causing agents. Even bacteria, so small that more than a million could fit on the head of a pin, have systems to defend against infection by viruses. This kind of protection gets more sophisticated as organisms become more complex.
A generator converts mechanical energy into electrical energy, while a motor does the opposite - it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.Nov 6, 2014
