Fluid mosaic is a term used to describe the current model of the cell membrane. Cell membranes are basically double layers (bilayers) of molecules called phospholipids.A mosaic is a structure made up of many different parts.<span> Mainly because of the way the plasma membrane is made up. It is fluid because it can wave and wobble like fluid, a bit sticky though. Due to the phospholipids sticking together. It is called mosaic because there are various proteins stuck inside the fluid creating a kind of patchwork or mosaic </span>
Answer: Biochemical engineers conduct studies on cells, proteins, viruses, or other biological substances to determine optimal conditions for growth or inhibitors that can stop or kill. They develop and conduct experiments to observe interactions of raw materials with each other and in specific environments.

Answer: By breathing out
Explanation: Breathing in oxygen and breathing out CO2.
(Cows also release CO2 by farting)

Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
