In an ionic bond the atoms are bound together by the attraction between oppositely-charged ions for example sodium and chloride form an ionic bond 

In a covalent bonds the atoms are bound by shared electrons in a true covalent bond the electronegativity values are the same, although in practice the electronegativity values just need to be close if the electron is shared equally between atoms forming a covalent bond then the bond is said to be nonpolar. Usually an electron is more attracted to one atom than to the other forming a polar covalent bond. For example the atoms in the water H2O are held together by polar covalent bonds.

A red blood cell has been placed into three different solutions. One solution is isotonic to the cell, one solution is hypotonic
Dmitry [639]

The type of solution in each beaker based on cell's reaction are :

  • Isotonic solution : Normal reaction
  • Hypotonic solution : The cell becomes turgid
  • Hypertonic solution : The cell becomes deformed

<h3>Matching each solution to the cell reaction </h3>

When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.

Hence we can conclude that The type of solution in each beaker based on cell's reaction are : Isotonic solution : Normal reaction, Hypotonic solution : The cell becomes turgid, Hypertonic solution : The cell becomes deformed

allochka39001 [22]

Answer: Clearly his SYMPATHETIC nervous system has been activated.

Explanation:

The effects of the sympathetic nervous system dominate in times of EMERGENCY or STRESS. And its effects include:

- dilation of pupils to help Gabe see sharply as he investigate

- inhibition of saliva secretion as his mouth turns dry

- acceleration of heartbeat due to fear

- stimulation of sweat glands to produce sweat.

All these show clearly that Gabe's SYMPATHETIC nervous system has been activated.
