<span>The Food Safety Manuel dictates that you scrub your hands for about thirty seconds. Scrubbing refers to rubbing soap over your hands, not the entirety of handwashing. One must then place their hands under running water for a suggested twenty seconds. Dry your hands using a blow dryer or a paper towel. Do not touch the sink handle after scrubbing your hands!</span>
Unfortunately this question is incomplete as no options are provided. IN actual fact,<span> four muscles are involved in mastication. Three of these are responsible for biting down, namely the masseter, the temporalis and the medial pterygoid, whereas one, the lateral pterygoid, is responsible for opening of the jaw</span><span>. All four muscles help to move the jaw laterally.</span>
Answer:
Explanation:
The cell membrane separates the cell from the outer environment. The extracellular fluid contains the sodium ions (Na+), chloride ions (Cl-), while intracellular fluid contains potassium (K +) and negative anions.
The potential difference arises when the membrane is selectively permeable to some ions. The resting potential is -70mV.
When the neurons get excited, the sodium ions start to enter by sodium channels.
Now there are more positive ions inside the cell membrane. It disturbs the resting potential i.e. -70mV. This stage is known as depolarization.
When the inside environment of the cell is more positively charged, the potassium ions start to move out of the cell. It goes out by the voltage-gated channels. Thus resting stage is maintained and it is known as repolarization.
But the initial stability of the cell membrane has to be maintained. To restore the resting stage, the sodium ions start to move out of the membrane and potassium ions enter into the cells again. This is an active transport and has done by the Na+ - K+ pump. Here 3 sodium ions move out and 2 potassium ions pumped into the cell through the plasma membrane.
Thus the resting potential regains. The potassium ions come back into the cells against the concentration gradient and ATP provides the energy for this phenomena.
No, it is usually caused my moving water, such as heavy rain or rivers or oceans.
Answer:
Sunlight and water.
Explanation:
The sun is the plant's most important nutrient. Plants convert sunlight into sugars in order to grow. Water is needed in two ways, it serves as both a solvent for mineral salts that are carried inside plant cells, and it is an essential component of photosynthesis. The questioner might have asked "name one" so they don't have enough information to answer with any greater certainty - but the answer remains the same regardless of how many nutrients they ask about.
Minerals are also required by plants in order to function properly including calcium, potassium, iron, magnesium just to name a few minerals which are found in healthy nutritious produce!
