I believe that what happens here is that when those cells carrying those intercellular signals do no pass through the connections, actually the signal is passed through or are transferred to adjacent cells for signal transmission, hence the answer is:

Explain what makes a cirrus cloud.
Ymorist [56]

Answer:

the answer is below

Explanation:

Cirrus clouds form from the ascent of dry air, making the small quantity of water vapour in the air undergo deposition into ice (to change from a gas directly into a solid). Cirrus is made up completely of ice crystals, which provides their white colour and form in a wide range of shapes and sizes.

Why is a phenol more acidic than a regular alcohol? Group of answer choices
Aleks [24]

Answer:

a.Phenols have the ability to spread out the negative charge that forms.

Explanation:

This happens because of  the aromatic ring the phenols have. When loosing the proton, the anion formed have different resonance isomers due to the double bonds in the aromatic ring. This resonance makes the anion more stable and prevents the reaction going backwards.

On the other hand, regular alcohol doesn't have resonace and the reaction of loosing the proton goes leftward and righward: is in equilibrium.

That equilibrium decreases the acidity of the alcohol.

When an arrhenius base is placed in h20 the only negative ion present in the solution is?
melamori03 [73]
According to Arrhenius theory of acid and base, Acids are those substances which when dissolved in water produces protons, while, Bases are those substances which when dissolved in water produces Hydroxyl Ions.

Example of Arrhenius Bases:

                         
NaOH ₍s₎ → Na⁺ ₍aq₎  +  ⁻OH ₍aq₎

                         LiOH ₍s₎ → Li⁺ ₍aq₎  +   ⁻OH ₍aq₎
Result:
           The only negative ion produced in water when Arrhenius Base is dissolved is ⁻OH (Hydroxyl Ion).
