Which type of model is a way of imagining how something works?
Answer:
mental model is an explanation of someone's thought process about how something works in the real world. It is a representation of the surrounding world, the relationships between its various parts and a person's intuitive perception about his or her own acts and their consequences. Mental models can help shape behaviour and set an approach to solving problems (similar to a personal algorithm) and doing tasks.

A magnet is different from a piece of iron that is not magnetic because
Answer:
Under normal conditions, a magnetic material like iron doesn't behave like a magnet because the domains don't have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction.

1. Ammonia gas occupies a volume of 450. ml at a pressure of 720, mm Hg. What
volume will it occupy at standard pressure?
Answer:
720+450 = 1170 it's 1170
426.32mL (rounded)
The formula for finding V2 is P1 • V1/P2 and since standard pressure (1atm) is equal to 760 P2 would be 760.
720mmHg • (450mL/760mmHg) = 426.32mL
What is a poverty line?
Dylan is completing an experiment in science class. The teacher gave Dylan a raw egg that had the shell removed. The egg is surounded by a membrane. Dylan gently placed the egg into a solution. Below is a diagram of the concentration of water molecules in the egg and in the solution.
Based on the diagram, what will happen to the egg?
A.
It will shrink because water molecules will move out of the egg until all the water molecules are in the solution.
B.
It will swell because water molecules will move into the egg until the concentrations are equal.
C.
It will swell because water molecules will move into the egg until all the water molecules are inside the egg.
D.
It will shrink because water molecules will move out of the egg until the concentrations are equal. HELPPPPPPPPPPPPPPPPPP PLS

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.
Explanation: if this isnt want you need tell me in the comments
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.

What general trend applies to solubility?
(a) Temperature is not related to solubility.
(b) As temperature goes up, solubility goes down.
(c) As solubility goes up, temperature goes down.
(d) As temperature goes up, solubility goes up.
Answer:
Basically, solubility increases with temperature. It is the case for most of the solvents. The situation is though different for gases. With increase of the temperature they became less soluble in each other and in water, but more soluble in organic solvents.
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

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

Transform Plate Boundary

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.
