3. When two atoms are combined what do they make?
Answer:
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound.

In the first generation, the beetles with the dark spotted trait had a better chance of
survival. The beetles changed their color to better adapt to their environment, and the
species evolved to have a lighter color.
In the first generation, the beetles with the dark spotted trait had a better chance of

In the first generation, the beetles with the dark spotted trait had a lower chance of
survival. The beetles changed their color to better adapt to their environment, and the
species evolved to have a lighter color.
Answer:
In the first generation, the beetles changed to have light spots. The beetles with the light spotted trait had a better chance of survival causing the species evolved to have lighter spots.
Answer:
In the first generation, the beetles with the dark spotted trait had a better chance of survival. The trait mutated over time, causing the beetles with that trait to be darker.
Explanation:
In the picture that I had, it shows that some of the beetles in the first generation started to develop spots on their back or wings. It shows that later down the line, their backs start to get even more darker which means that is must be a trait that mutated over time that would allow the beetles with that trait to be significantly darker. They can't just change their traits if they want to so it would have to be something like mutation that caused it.
I need chemical properties of matter that can be classified.
Answer:
Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

why does the d block start in the fourth row of the periodic table
Answer:
Why does D-block start on the fourth row of the periodic table?
Explanation:
The require more energy to reach 3d than 4s, and they fill up 4p before 4d, and so forth. ... The energy is lower for 6s than 4f, and 4f and 5f are lower in energy than the final D level.

A teacher asks students to make a model of a transform plate boundary. The

Transform Plate Boundary

Plate
Which event can the student best demonstrate with their model?
Answer:
C Earthquake
Explanation:
I just took this test and it’s on Quizizz
The event which best describes the model is an Earthquake. Earthquake is
formed when two plate boundaries collide with each other.
The plate boundaries colliding results in them being stuck. Pressure then
builds up between them which results in the plates breaking loose as time
goes on.
The movement that results from the plates breaking loose is what results in
an earthquake being experienced.

Explanation:
If a substance is a bad conductor as a solid, but a good conductor as a liquid or when dissolved into water, which type of bond is holding the compound together?
The bond type in the substance is ionic bonding because, ionic compounds in their solid state are not conducting but the ions they furnish when dissolved in water conducts electricity.
What are ionic compounds ?Ionic compounds are formed between metals and nonmetals. Metals are electropositive and they can easily loss electrons to from cations. Metals donate electrons to the electron deficient non metals to achieve octet.
Ionic bonding is a strong electrostatic force between opposite charged ions. Hence this bond is stronger than other types of bond. This intact bonding make them bad conductors in the solid state.
However they are electrically conducting the molten state or when dissolved in water due to the presence of free ions and electrons in the solution.

How many cm3 are contained in 3.83 x 107 mm3?
Answer:
3.38 x 10⁴cm³
Explanation:
Given that:
Volume of the substance = 3.83 x 10⁷mm³
The problem entails use to convert from mm³ to cm³;
1000mm³ = 1cm³
So;
3.83 x 10⁷mm³ will produce [tex]\frac{ 3.83 x 10^{7} }{1000}[/tex] = 3.38 x 10⁴cm³
