Normal flora can be a barrier to entry in several ways. The living bacteria that lives in our bodies wants to stay living there. If another organisim comes along it is going to protect it's territory, so to speak. They have defensive mechanisims to prevent other bacterial intruders from gaining entry to the body.
Lactic acid fermentation occurs due to the lack of oxygen in the the muscle cells Aerobic respiration requires oxygen as an electron receiver to complete the electron transport system, so without it, the cells will be unable to undergo normal respiration and will resort to lactic acid fermentation
A normal lactic acid test typically shows levels within the range of 0.5-2.2 millimoles per liter (mmol/L) in the blood. Elevated lactic acid levels may indicate conditions such as sepsis, liver disease, heart failure, or hypoxia. Conversely, low lactic acid levels are less common but may be seen in rare genetic conditions or certain types of anemia.
During vigorous physical activity, muscles may rely on anaerobic respiration to produce energy when oxygen supply is limited. This process produces lactic acid as a byproduct, which can build up in muscles and contribute to the sensation of cramping. Additionally, the accumulation of lactic acid can disrupt normal muscle function, leading to cramps.
Under normal circumstances, your cells produce the energy they need to move and/or resist loads by combusting sugars (aerobic). There are, however, circumstances in which the supply of oxygen to cells is insufficient to keep up with the demand. one example of this might be muscle cells in the legs of someone who is sprinting a long distance. the sprinting person cannot breathe in oxygen fast enough to supply the muscle. another example could be a pathological condition such as a heart attack. without proper blood flow - blood will not get oxygenated and as a result muscles will have to work in the absence of oxygen (even for someone "at rest" when cells must obtain their energy in the absence of oxygen, the metabolic by-product is lactic acid.
In normal, unspoiled milk, there are no acids found. As milk starts to spoil, lactic acid becomes the predominate acid.
yes.
The line perpendicular to a barrier is called the normal.
a normal
Lactic acid is not considered volatile at room temperature, as it is a non-volatile organic acid. Its vapor pressure is low, and it is unlikely to vaporize into the air at normal conditions.
the line is called the normal
Lactic acid is not considered flammable by GHS.
No.
nothing, its a normal component of gastric juice like HCl.

It's when your body doesn't have enough oxygen to perform the "normal" process of creating energy, or ATP. Without the oxygen, our bodies perform lactic acid fermentation, which still produces energy but not as much as the one with oxygen. That energy is stored in the form of lactic acid.
Yes, it is normal for boys to hang out with girls. Gender does not have to be a barrier for friendships. It is healthy and beneficial for individuals to have a diverse group of friends.
