Answer:
a. muscle contraction of sustained force resulting from repeated action potentials.
Explanation:
Tetanus is a symptom consisting of the constant contraction of one or more muscles. This can be caused by diseases or other physiological conditions that cause an increase in the frequency of action potentials that promote muscle contractions. Thus, the contractions overlap each other and consequently the muscle remains in a condition of constant contraction.
Answer:
the answer is parasitism
Explanation:
the parasite benefits by taking nutrients, and the other is losing it.
Answer:
- flippases translocate lipids from outer (extracellular) leaflet to inner (cytosolic) leaflet,
- floppases, move phospholipids from inner (cytoplasmic) leaflet to outer (extracellular) leaflet, ABC transporter, move phospolipids across the lipid bilayer down the concentration gradient
- scramblases Not ATP-dependent, Activation may result in increased membrane lipid symmetry, translocate phosphatidylserine, preventing apoptosis and engulfment by macrophages,
Explanation:
Flipases are transportes that require energy for their functioning (ATP dependent) beause they move phospolipids across the lipid bilayer against the concentration gradient (from extracellular side to cytosolic side).
Floppases are ABC transporters, opposite than flippases (move phospholipids from the cytosolic side).
Scrablases are bidirectional transporters, responsible for asymmetry formation. It also enables exposure of phosphatidylserineon the outer leaflet when it is necessary.
Oxygen - It is very important for all living to survive 'cause without it, cellular respiration can't take place....
Glucose - It is the simple food, it provides energy to the whole ecosystem, so that they can survive.
Without either of them, life is not possible!!!!!
