Write a paragraph comparing protons, neutrons, and electrons. Be sure to include mass, location, and electric charge.
Answer:
Explanation:
Dalton's Atomic Theory explained a lot about matter, chemicals, and chemical reactions. Nevertheless, it was not entirely accurate, because contrary to what Dalton believed, atoms can, in fact, be broken apart into smaller subunits or subatomic particles. We have been talking about the electron in great detail, but there are two other particles of interest to us: protons and neutrons. We already learned that J. J. Thomson discovered a negatively charged particle, called the electron. Rutherford proposed that these electrons orbit a positive nucleus. In subsequent experiments, he found that there is a smaller positively charged particle in the nucleus, called a proton. There is also a third subatomic particle, known as a neutron.
Protons, neutrons, and electrons are fundamental particles that constitute the building blocks of atoms.
Protons and neutrons are found in the nucleus, the central core of the atom, whereas electrons are located in electron shells surrounding the nucleus. Protons carry a positive electric charge and have a mass of approximately 1 atomic mass unit (amu).
Neutrons, on the other hand, are electrically neutral, meaning they have no electric charge, but they also have a mass of about 1 amu. Electrons, which are much smaller than protons and neutrons, have a negligible mass of approximately 1/1836 amu and bear a negative electric charge that exactly balances the positive charge of protons, resulting in an overall neutral charge for the atom. The combination of these three particles determines an element's chemical properties and behavior in chemical reactions.

Answer: I don't understand the question.
Answer: The completed sentences of the Question are as follows:
The Cell-wall supports and protects a plant cell. It gives the cell its rigid structure.
Turgor pressure helps the plant stand upright. It is caused by the movement of water into a plant cell.
Plants are composed of cells that contain nuclei, which make them eukaryotic cells.
Plants make their own food using sunlight, which makes them autotrophs.
Explanation:
The cell wall is a rigid covering that protects the cell. It also provides structural support and gives shape to the cell.
Turgor pressure in plants is the force exerted by stored water on a cell wall. Turgor pressure is critical to the plant’s essential processes as it stiffens and rigidifies the plant cell and helps it stay upright.
Plant and animal cells are eukaryotic which means that they have nuclei. Eukaryotic cells are found in both plants and animals.
Plants are autotrophs, which means they produce their own food. The process by which they produce their own food by transforming water, sunlight, and carbon dioxide into oxygen and simple sugars is called Photosynthesis.

Blake is using a screw to hang on a picture in his room. Which of the these is the best description of a screw?
A. A screw allows you to use less force because a screw acts like a pulley.
B. A screw allows you to use less force because a screw acts like an inclined plane.
C. A screw allows you to do less work because a screw acts like a pulley.
D. A screw allows you to do less work because a screw acts like an inclined plane.
When using a screw to hang a picture, it is important to understand its function. The best description of a screw is option B - "A screw allows you to use less force because a screw acts like an inclined plane."
Screws are simple machines that have an inclined plane wrapped around a cylinder. This inclined plane is known as the thread. As the screw is turned, the thread pulls the screw into the material it is being screwed into, allowing it to hold on tightly.
Because of this design, screws are able to reduce the amount of force needed to hold an object in place. This is because the force applied to the screw is spread out over a larger area, making it easier to turn the screw and insert it into the material.
In conclusion, when using a screw to hang a picture or any other object, remember that it is an inclined plane wrapped around a cylinder, designed to reduce the amount of force needed to hold an object in place.
Answer: The answer is B! <3
Explanation:
When Blake puts a screw into his wall, it is a good description of an inclined plane. The threads of a screw act like an inclined plane to increase the distance over which you exert the input force. As the threads of the screw turn, they exert an output force on the wood, pulling the screw into the wood. So the answer is B. I hope this helped! :)

Answer:
A. Palms and other small trees
Explanation:
Understory Layer
Located several meters below the canopy, the understory is an even darker, stiller, and more humid environment. Plants here, such as palms and philodendrons, are much shorter and have larger leaves than plants that dominate the canopy. Understory plants’ large leaves catch the minimal sunlight reaching beyond the dense canopy.

Max and Jimmy want to jump on a trampoline. Max begins jumping in a steady pattern, making small waves in the trampoline. Jimmy starts jumping on the trampoline too. Suddenly, Max goes twice as high even though he did not put any extra effort into jumping.
What type of wave interaction is this? Explain how it occurred.
Answer: The wave interaction described in the scenario is known as constructive interference.
Explanation:
Constructive interference occurs when two waves meet and combine in such a way that their amplitudes add up, resulting in a larger wave. In this case, Max's steady pattern of jumping creates small waves on the trampoline, with a certain amplitude.
When Jimmy starts jumping on the trampoline, his waves combine with Max's waves. If the peaks and troughs of both waves align perfectly, they will add up, resulting in a wave with a larger amplitude. This alignment of peaks and troughs leads to constructive interference, causing Max to go twice as high without any additional effort.
The reason behind this phenomenon lies in the nature of waves. When waves meet, their amplitudes can either add up or cancel out, depending on their relative positions. In the case of constructive interference, the peaks of one wave align with the peaks of the other wave, and the troughs align with the troughs, resulting in an increased amplitude. Conversely, in destructive interference, the peaks align with the troughs, leading to a cancellation or reduction in amplitude.
So, in the scenario, Jimmy's waves align with Max's waves in such a way that their amplitudes combine constructively, resulting in Max going twice as high on the trampoline without exerting any extra effort.

In the following images, a blue circle represents an atom of one type of element, and a red square represents an atom of a second type of element. Determine which of them represent a pure substance, a homogenous mixture, and a heterogeneous mixture.
Are these in the right order?
Answer: No they are not. "Pure substance" is supposed to be placed in the middle picture. "Homogenous mixture" is supposed to be placed in the right picture. "Heterogenous mixture" is supposed to be placed in the left picture.
Explanation:
Pure Substances:
There are two categories of pure substances: elements and compounds (In our case, we have a compound).
Element (e.g. the blue circles or the red squares):
An element is a fundamental substance.An element cannot become simpler than itself, even if chemical separation methods are used.Compound (e.g. the blue circles bonded together with the red squares in the middle picture):
A compound is a substance made of two or more elements in fixed proportions (i.e. One element has the same amount as the other).A compound can be made into individual elements or simpler substances using chemical methods of separation.Mixtures:
There are two categories of mixtures: homo- and hetero- genous.
Homogenous mixture:
The substances or elements are mixed to look like one single substance and cannot be told apart (e.g. When salt dissolves in water, the water still looks like water).The substances or elements are distributed evenly throughout the apparatus. The number of different types of substances or elements can vary (e.g. There is more water than salt) The substances or elements do not bond together.Heterogenous mixture:
The substances or elements are mixed and can be told apart (e.g. When oil is mixed with water, the oil is "water-hating" so it forms its own layer on the bottom, while the water forms another layer on top of the oil layer).The substances or elements are distributed where one type of substance or element is bunched up in one spot and another substance or element in another spot.The number of different types of substances or elements can vary.The substances or elements do not bond togetherThe second Image is not a homogenous mixture, it is a heterogenous mixture as two different types of elements are mixed together.
The mix of two different types of elements in the heterogenous mixture is not uniform and has uneven mixed types.
The third image is a homogenous mixture as even though two different types of elements are together, they are not mixed with each other.
Unlike in the heterogenous mixture, in a homogenous mixture, there is a uniform mix of two different types of elements.
The first image is correct, the image depicts a pure substance.
