Answer: A tree grows taller.
Explanation: Cells divide for many reasons. They may divide for growth, death, or to replace something. The cells divide when growth is happening, to allow to produce more cells. For example: When a tree grows taller the cells divide so they can produce more cells. The places in trees where these cell divisions happen, are called “Meristems”. This is where all the activity happens.

Give two differences between the properties of iron and sodium
Answer:
Iron have 26 atomic and sodium have 11 atomic
Explanation:
The sodium is a non-transition metal. Its melting point is low and boiling points and is a soft metal, whereas iron is a transition metal with very high melting and boiling points, It is a hard metal.
What is transition metal ?The term transition metal is defined as any of various metallic elements such as chromium, iron, and nickel that have valence electrons in two shells instead of only one.
Between the s-block and p-block elements in the periodic table are transition metals. As a result, they are known as d-block elements.
Sodium is soft, has a much lower melting point than water, and reacts with it violently, producing heat and hydrogen or even exploding. Additionally, sodium and water react to create a hazardous compound.
Thus, these are difference between the properties of sodium and iron.

Explain why the name 1-propene is incorrect.what is the proper name for this molecule
Answer:
Explanation:
Explain why the name 1-propene is incorrect what is the proper name for this molecule
The name 1-propene is incorrect because;
It is not necessary to indicate the position of the double bond. Whichever way you decide to flip it, the double bond will always be at the first carbon.The proper name for this molecule is;
PropenePropene otherwise known as propylene is simply propane with a double bond at the first carbon.
When we get to the alkenes where the naming of organic compounds becomes more complex, the numbering system is used to indicate the position of the bonds.
With propene, there are three carbon atoms and the double bond will always appear in between two of the carbon atoms.
So, it is not important to use numbers to show that the carbon is at the first carbon. This becomes necessary from the next compound, butene, where there are more carbons.

A wave hits a wall as shown. A brick wall with a green arrow pointing to the wall from below and right at a shallow angle. Another green arrow starts where the first arrow touched the wall and goes up and left at the same shallow angle. As the wave interacts with a wall, which kind of wave interaction is shown?
Answer:
A wave reflection interaction (reflected by the wall)
Explanation:
In a reflection, the propagating wave is bounced off the reflecting surface because the medium of the surface prevents the propagation of the wave through it, such that wave is redirected at an angle equal to the angle of incident on the reflecting surface
Reflection takes place with the different forms of waves, such as sound wave, water waves, and light wave
The objects around us are seen with the aid of reflection of light from a light source such that the reflected light enters our eyes after being reflected on the surface of the object, and the object is seen.

A little boy places an ice cube in his hot bowl of stew and then walks out of the room. When he returns, the ice cube is gone.
Based on the law of conservation of mass, what happened to the ice cube in the scenario?
a. The extreme temperature difference between the stew and the ice cube caused the ice cube's mass to be converted into energy.
b. The extreme temperature difference between the stew and the ice cube caused the stew's mass to destroy the ice cube's mass.
c. The extreme temperature difference between the stew and the ice cube caused the ice cube to change state while its mass remains the same or constant.
d. The extreme temperature difference between the stew and the ice cube caused the ice cube's mass to shrink to a barely noticeable amount.
Answer:
It's actually C
Explanation:
The Ice's mass was never destroyed, just converted therefore it would be C, which states the mass never disappeared, just changed to water.

The Periodic Table is known to be an array of chemical elements that are organized in order of their increasing atomic number. That arrangement gives a recurring pattern known as the periodic law in their properties.
Periods are found in the horizontal rows (across) the periodic table, while groups are found in the vertical columns (down) the table.
The Periodic Table was discovered by D.I Mendeleev.
When ammonium chloride is dissolved in water, the beaker gets cold. Which type of reaction does this describe
O exothermic
O endothermic
O both exothermic and endothermic
O neither exothermic nor endothermic
Answer:
B
Explanation:
i think with exothermic reactions heat is released
this is what i looked up
hope this helps i took chem last year and think this is what i learned
Considering the definition of exothermic and endothermic reactions, the correct answer is second option: the reaction is endothermic.
Energy and chemical reactionsEnergy is the ability to do work or to produce heat.
Remembering that chemical reactions involve a reorganization of atoms between substances with breaking or formation of chemical bonds, this formation or breaking of chemical bonds is accompanied by changes in the energy of the system.
Exothermic reactionsChemical reactions that release heat are called exothermic. That is, an exothermic reaction is one where energy flows out of the system.
So, at room temperature, the heat released by a chemical reaction is enough to cause a rise in temperature.
Endothermic reactionsAn endothermic reaction is one that requires heat to take place. In other words, a chemical reaction is endothermic when it absorbs energy from the environment.
In this case, the heat is transferred from the outside to the inside of the system. By absorbing heat, the effect of an endothermic reaction is to lower the temperature.
This caseWhen ammonium chloride is dissolved in water, the beaker gets cold. That means the system is absorbing heat from the surrounding and the temperature does down.
So, the correct answer is second option: the reaction is endothermic.

(1) In an experiment for determining the density of water, the following results
were recorded.
-mass of an empty beaker = 65gm.
- mass of the beaker and water = 165gm.
the volume of water = 100Cm.
(Calculate the density of water)
Given parameters:
mass of an empty beaker = 65gm
mass of the beaker and water = 165gm
volume of water = 100cm³
Unknown:
Density of water = ?
Solution:
Density is the mass per unit volume of a substance;
Density = [tex]\frac{mass}{volume}[/tex]
To find the mass of the water ;
Mass of water = Mass of beaker and water - mass of an empty beaker
= 165g - 65g
= 100g
So input parameters and solve;
Density = [tex]\frac{100g}{100cm^{3} }[/tex]
Density of the water in the beaker = 1g/cm³
