Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)

The Organelles help the cell to function efficiently.
What are the organelles in the cell?I can see that your question has to do with the organelles in the cell but I don't quite get the analogies that you intend to use. However, I would explain the organelles one after the other.
Endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells. It serves as a transport system for proteins and lipids, as well as a site for folding and modification of newly synthesized proteins.
Ribosomes: Ribosomes are complex molecular machines that are found in the cytoplasm of all living cells. They are responsible for synthesizing proteins from amino acids, which are the building blocks of proteins.
Mitochondria: These are organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).
Vacuole: Vacuoles are membrane-bound organelles found in eukaryotic cells. They are large, fluid-filled compartments that serve several important functions within the cell, including storage of nutrients and waste, regulation of the cell's water balance, and maintenance of cell shape.
Cytoplasm: Cytoplasm is the gel-like substance that fills the interior of eukaryotic cells, excluding the nucleus. It is a complex mixture of water, ions, organic molecules, and a variety of cellular structures, including organelles such as mitochondria, ribosomes, endoplasmic reticulum, and lysosomes.
Lysosomes :Lysosomes are membrane-bound organelles found in eukaryotic cells. They are referred to as the "garbage trucks" of the cell because they are responsible for breaking down and recycling cellular waste and unwanted material.

Part 3: Writing to the People of Westfield
Dr. Yung wants you to explain what the reddish-brown substance is to the people of Westfield. As you write your argument, remember to:
state your claim about the identity of the reddish-brown substance.
use evidence from both your observations and the atomic-scale models to support your claim.
include the vocabulary words listed below in your argument.
Chapter 1 Question: What is the reddish-brown substance in the water?
Claim 1: The reddish-brown substance is the same as the substance that makes up the pipes.
Claim 2: The reddish-brown substance is the same substance as the fertilizer.
Claim 3: The reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes.
Word bank: atom, model, property, substance
Answer:
Dear People of Westfield,
As you may be aware, there has been a lot of concern about the reddish-brown substance found in the water supply. After conducting extensive research and analysis, I am here to share my findings with you.
Based on my observations and the atomic-scale models, I can confidently state that the reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes. In fact, the reddish-brown substance has its own unique set of properties that distinguish it from these other substances.
One of the key pieces of evidence supporting this claim is the atomic-scale model of the reddish-brown substance. This model shows that the substance is made up of its own distinct atoms arranged in a specific way. These atoms have unique properties, such as their size and charge, that differentiate them from the atoms that make up the fertilizer and the pipes.
Furthermore, my observations of the reddish-brown substance also support this claim. I have noticed that the substance behaves differently than both the fertilizer and the pipe material. For example, the substance dissolves at a different rate and reacts differently to various chemicals.
In conclusion, it is clear that the reddish-brown substance in the water supply is its own unique substance, with its own distinct properties and atomic makeup. It is not the same as either the fertilizer or the substance that makes up the pipes. I hope that this explanation provides some clarity and reassurance to the people of Westfield.

Deanna stirred a teaspoon of sugar into a glass of warm water. The sugar completely dissolved in the water. The statement that is true about the dissolved sugar is the sugar forms a mixture with the water. Therefore, option D is correct.
What do you mean by solubility ?The term solubility is defined as the maximum amount of a substance that will dissolve in a given amount of solvent at a specified temperature.
Temperature, pressure, polarity, and molecular size are all factors that influence solubility. For most solids dissolved in liquid water, solubility increases with temperature. This is due to increased vibration or kinetic energy of the solute molecules at higher temperatures.
Water is known as the "universal solvent" because it dissolves more substances than any other liquid. This is critical for all living things on the planet.
Thus, the dissolved sugar is the sugar forms a mixture with the water, option D is correct.

When water vapor is cooled, it re-forms into water droplets. Why does this represent a conservation in mass?
50 POINTS!!!
Answer:
People, especially kids, tend to think that when water evaporates it just disappears, or turns into the air. But we know based on the law of conservation of mass that any time water changes state it keeps the same mass!
Similarly, when water vapor turns to water droplets, when it goes from its gas to its liquid state, it still has the same mass. It's just in a different phase. This is a perfect example of conservation in mass!
When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

20. How can a microscopic paramecium and a large giraffe both be described by the cell theory?
Answer:
The two types of cell are:
-Eukaryotic cell
-prokaryotic cell
Description:
Eukaryotic cell: These are organisms who have a nucleus enclosed within a nuclear envelop. It does not have a cell wall unlike prokaryotes. It has mitochondria and other cell organelles.
Prokaryotic cell: Organisms with no distinct nucleus and other major cell organelles.
We humans are made up of Eukaryotic cell type as we have membrane bounded nucleus and all the essential major organelles to perform vital body function. Humans have complex organization of cells. Cells have cytoskeleton and organelles surrounded by cytoplasm.
Bacteria are prokaryotic, as they have cell wall made of peptidoglycan, they lack nucleus and membrane bounded organelles. Hence considered to be unicellular life forms.
Similarities between prokaryotes and Eukaryotes:
-Both have cell membrane
-Both have genetic material
- Both have ribosome
-Both have cytoplasm
-Both have vacuole
5. The cell wall is like House because it protects the family members inside as cell wall protects the substance inside the cell.
6. The cell membrane is like airplane because it allows passenger to come in and go out the way cell membrane allows substances to enter and leave.
7.The vacuoles is like a basketball because both acts as storage, basket ball stores air and vacuole store other substance.
8.nucleus
9.Vacuole
10.Cytoplasm
11. Cell wall
12.Chloroplast
13. Nucleus
14.Cheek will have greater number of Mitochondria as great function and more energy required which will be released in form of ATP.
15. Differences:
1.Animal cell do not have cell wall whereas plant cells have cell wall.
2. Animal cells have several small vacuoles whereas plant cells have one large nucleus.
3.Plant cells have chloroplast but Animal cells don not.
16.Plants have single large vacuole as it performs two main function
i)To keep the plant upright
ii)To store water
Large vacuole protect cell from potential harm.
17.In plants chloroplast main function is to synthesis food whereas in humans there is no such need as they get sugar from the food they eat.
18. components of cell theory:
1. All living things are composed of cell.
2.Cells are basic units of structure and function for two living beings.
3.All cells come from pre existing cells.
19. All living things are composed of cell:
Experiment:
