Answer:
element Y and Z
Explanation:
Having on valence electron indicates that these elements are on the same column/group of the periodic table. Both these elements will bond with a -1 charge.
The concentration of Na+ is greater inside the cell, and the concentration of K+ is greater outside the cell.
The concentrations of Na+ and K+ are both greater outside the cell.
The concentrations of Na+ and K+ are both greater inside the cell.
The concentration of Na+ is greater outside the cell, and the concentration of K+ is greater inside the cell.
Answer:
It speeds up the reaction rate
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Answer: The correct answer is: C The are the same except osmosis specifically and only involves water.
Explanation:
Osmosis is the process in which a solvent moves across a semipermeable membrane in order to dilute a concentrated solution and it ends up equalizing the concentration of the solution at both sides of the cell membrane.
On the other hand, diffusion occurs when particles move from an area of higher concentration to an area of lower concentration and it ends up equalizing the concentration.
So the main difference is the presence/ Lack of water in the processes.
In conclusion the correct answer is : C.
When performing rescue breathing be sure to always tilt the head before performing breaths. It involves the following steps; place the person on their back, tilt their chin up to open the air way, Two fingers under the chin and one hand on the forehead, tilt the head back gently and open their mouth, pitch the nose and create a seal with your mouth around the other person's mouth , and then give the person 2 small breaths first, then continue by giving one breath every 5 seconds.
