Classify each label into the correct category of human red blood cell.
Mazyrski [523]

Classifying each label into the correct category of human red blood cell

A) Human red blood cell shrinks    

  • Cells placed in hypertonic solution
  • More water moves out of cell

B) Normal Human red blood cell

  • Cell placed in isotonic solution
  • Water enters and leaves at the same rate

C) Human red blood cell swells

  • Cell placed in hypotonic solution
  • More water moves into cell

<h3>Types of solution</h3>

A hypertonic solution is a solution with a higher concentration to its surroundings ( i.e contains more solutes like electrolytes than its surroundings ). when a cell is placed in such solution is shrinks gradually and dies off through a process known as plasmolysis. while a hypotonic solution is a direct opposite of a hypertonic solution. Also An isotonic solution is a solution with the same concentration with its surrounding solution.

Hence we can conclude that the classification of each label into the appropriate category are as listed above.

Which reaction will most likely take place based on the activity series? li &gt; k &gt; ba &gt; ca &gt; na &gt; mn &gt; zn &gt;
Ivenika [448]

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃

<h3>Activity Series</h3>

From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.

Let us look at each of the given options;

A) Ag + FeCl₃

From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.

B) Zn + CaO

Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.

C) Ba + Na₂CO₃

Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.

D) Cr + KNO₃

Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.

Complete question is;

Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt

A. Ag + FeCl₃

B. Zn + CaO

C. Ba + Na₂CO₃

D. Cr + KNO₃

DochEvi [55]
<h2>Answer with Explanation </h2>

To discover average you include the scores from each subject and afterward separate them by what number of various numbers you have.  An example is shown below, like if there were three subjects who got different scores. The next step would be to add the score of all subjects.

Example

- 1+2+3=6  

After adding the total sum will be divided by the number of students.

- 6/3=2  

When you have the midpoints of all subjects over the 4 years, the one that is most noteworthy will be answer.
