Have you had the chance to watch a tree grow over a span of several years? Did you notice that the tree grew thicker and taller?

Deep in the roots of the tree and high in the growing shoots are meristem cells. Each year, the meristem cells help the tree continue to grow.
When the seed of a tree first starts to grow, what would happen if the cells did not differentiate?

The seed could form roots, but not leaves.

Other cells would differentiate.

The DNA would make new cells.

All of the cells would be identical.

AlekseyPX

Answer:

B. the resonance hybrid of all structures

Explanation:

The idea of resonance is used to explain bonding in compounds where a single structure does not fully account for all the bonding interactions in a molecule.

A number of equivalent structures are then used to show the nature of bonding in such a molecule. Such structures are called resonance structures or canonical structures. None of these structures individually offer a holistic explanation to the bonding interactions in the molecule under study.

However, a hybrid of all the canonical structures does explain the nature of bonding in the molecule.

andrey2020 [161]

Neutralization reaction is the reaction that occur between acid and base.

<h3>What is Neutralization reaction?</h3>

Neutralization reaction is the reaction that take place between acid and base to produce salt and water. For examples HCl react with NaOH to produce NaCl and H2O

Therefore, Neutralization reaction is the reaction between acid and base.

The question is not complete but the option are gotten from another website.

Here are the options.

  • an acid and a base
  • a fuel and oxygen
  • an acid and a metal

Reema took 5ml of Lead Nitrate solution in a beaker and added approximately 4ml of Potassium Iodide solution to it. What would s
Brrunno [24]

She would observe a yellowish  solid precipitate which is the lead iodide and a white solid precipitate which is the potassium nitrate.

This is because the lead nitrate solution which contains particles of lead will mix with the potassium iodide solution containing  particles of iodide. Upon mixing,the  lead particles  from the Lead nitrate solution combines with the  iodide particles from Potassium iodide and form two compounds, a yellowish solid precipitate called lead iodide and a white solid  precipitate called Potassium nitrate.

The formation of entirely two new compounds is known as the double displacement reaction and can be written in a chemical equation as  

2KI(aq.)+Pb(NO₃)₂(aq.)------>2KNO₃(aq.)+PbI ₂(s)
