possible gametes for each = EH / Eh / eH / eh

where,

EH Eh eH eh

EH EEHH EEHh EeHH EeHh

One eye One eye One eye One eye

One horn One horn One horn One horn

Eh EEHh EEhh EeHh Eehh

One eye One eye One eye One eye

One horn Two horn One horn Two horn

eH EeHH EeHh eeHH eeHh

One eye One eye Two eye Two eye

HELP FAST! PHYSICAL SCIENCE salt is added to a flask of water. the flask is sealed and shaken for several minutes.After being sh

densk [106]

Answer:the following can be done to allow more NaCl to dissolve;

1.) heating the mixture.

2.) Addition of extra water to the solution.

Explanation:

When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation. Now when the solution is heated, the rate of the dissociation between the two molecules increases leading to more dissolution of NaCl. Also in the absence of heating, more Water molecules can be added to the solution to decrease it's saturation thereby favouring the dissolution of more NaCl.
