The outermost layer is called as Crust. The middle layer is called as Mantle and the last layer is called as The Core. This core is further divided into two parts namely Inner core and Outer core.
The four strata of EarthEarth has four distinct strata. According to geologists, when the Earth cooled, the denser, heavier material sank to the center and the lighter material rose to the surface.
Because of this, the innermost layer is composed of nickel and iron, and the outermost layer is formed of the lightest materials, such rocks and granite.
The Layers of EarthThe four layers of the earth are its inner core, outer core, mantle, and crust. The crust, mantle, and core are the three major layers of the planet.
Despite making up only 16.1% of the planet’s volume, the core accounts for over half of its radius. Only a little portion (1.4%) of Earth’s total volume (82.5%) is made up of its crust.

Penny Experiment
Which liquid slowed the speed of light the most? Explain how this is related to the index of refraction of that liquid.
Water
Soapy Water
Answer:
You might have heard people talk about Einstein’s speed of light, and that it’s always the same. The part that most people leave out is that this is only true in a vacuum—when there’s no pesky molecules of air or water to slow it down. But when light moves through a more familiar medium like air, it moves more slowly due to the interactions of individual photons with the molecules in the material. In general, the more optically dense the medium, the slower the light will move. So what happens to the light when it goes from one medium to another?
Light changes speed
Imagine that you and your friends are at the beach. You all decide to swim together, so you link arms and approach the water as a straight line. As you start walking into the water, you all slow down, because it’s harder to walk through water than through air. So imagine that you approach the water at an angle relative to the shoreline. The person on the end will meet the water and slow down first, then the next person in line, then the next, until everyone is walking through the water. Because one end of the line slowed down before the other end, the line of people becomes crooked, with the people who are still on the beach at a different angle relative to the water’s edge than the people who have already entered the ocean.
Beach example diagram
You can say that the water bends the path of of each individual toward a normal line drawn perpendicularly to the shoreline, since the people still on the shore are bent further away from the shoreline than those in the water.
The same thing happens to a light ray when it moves from air to water, or from any fast medium to a slow medium: it bends toward the normal.
Light ray bending to normal diagram
Least time principle
Another way to think of this is to imagine you and your friend are racing out to a raft in the middle of a lake. You have to travel across a beach and then through the water.
Beach and raft example diagram
Your friend decides to make a beeline for the raft and runs down the beach. You know that you can run faster than you can swim, so you head toward the water at an angle so that you run for longer than you will swim.
Beach and raft example diagram with paths overlay
Sure enough, your strategy pays off, and you get to the raft first. Your friend took the shortest path in terms of distance, but you took into account the difference in speed in each medium, and took the shortest path in terms of time. That means you took the path of least time.
Light does exactly that when moving between mediums. It takes the path that will take the shortest amount of time, when you account for the difference in speed between the mediums.
For example, imagine you are looking out the window. You have air, glass, and then air again. Glass is denser than air, so the light from outside passes from a fast medium, through a slow medium and into a fast medium again. The light will take the path from outside to your eye that spends the least time
Light diffraction through glass diagram
You can also see that the rule from earlier still applies: when the light enters the glass the ray is bent towards the normal. When it leaves the glass, it is bent away from the normal, and regains the same angle as before it entered the glass.
Light diffraction through glass diagram with overlay
Consider the following
Say you’re at the aquarium, and there’s a tank that’s totally full of water, so there’s glass over the top and sides. If you stand back a little, you can see the same stingray through the top of the tank and the wall of the tank.
Aquarium refraction diagram
Because you see the light coming through the glass at two different points, you see two images of the same stingray.
Alex opens the bread drawer and discovers a moldy loaf of bread. Describe what alex can conclude about the mold using the cell theory?
Based on the cell theory, Alex can conclude that a particular kind of fungus called mold grows on both plants and mammals. It resembles a cluster of mushrooms under a microscope.
The roots that the stalks, or sporangiophores, are linked to enlarge as they mature into soft meals like bread. Sporangia, which create spores that launch into the air and drift to a new host to multiply, are found atop the stalks.
What are Fungi?Fungi are a group of spore-producing organisms, such as molds, yeast, mushrooms, and toadstools, that feed on organic matter.The presence of chitin in fungi's cell walls distinguishes them from plants, bacteria, and some protists and separates them into a separate kingdom. Like animals, fungi consume matter that has already been dissolved in their surroundings. Typically, this is done by secreting digestive enzymes into the environment. They do not photosynthesize, fungi. They move through growth, except spores (some of which are flagellated), which can move through the air or water. In ecological systems, fungi play a key role in decomposition.The nuclei of fungal cells are membrane-bound and contain chromosomes with coding and non-coding DNA segments known as exons and introns, respectively. Membrane-bound cytoplasmic organelles found in fungi include mitochondria, membranes containing sterols, and ribosomes of the 80S type.To learn more about Fungi, refer to:

Explanation:
13) Write two problem questions about something you can observe right now then write two hypotheses for the problems previously created.
The hypotheses "pollutants can drastically affect global temperature" or "chlorofluorocarbons effectively alter the ozone layer" can be used to investigate two potential questions, including how pollutants might affect global warming and why chlorofluorocarbons harm the ozone layer.
How do hypotheses work?A hypothesis is a proposed explanation for a phenomenon (plural: hypotheses). If a hypothesis cannot be tested by the scientific process, it cannot be referred to as a scientific hypothesis. Observations from the past that cannot be fully explained by the body of knowledge at this time often serve as the foundation for scientific ideas. Although the phrases "hypothesis" and "theory" are sometimes used synonymously, a scientific hypothesis is distinct from a scientific theory. A recognized theory that has gained shaky support and is advanced for further study is called a working hypothesis.
Therefore, we may conclude that by using the scientific method, which comprises conducting experiments to support or deny the hypothesis, hypotheses like, for example, whether pollutants may effect global warming by acting as greenhouse gases, can be solved.

A phenotype where only a single allele is sufficient for expression.
Polygenic traits are traits that are influenced by more than one gene such as height or skin color. Because multiple genes are involved, polygenic traits do not follow Mendelian inheritance patterns. A pleiotropic gene is a single gene that controls multiple traits. While studying the genetics of peas.
Gregor Mendel made an interesting observation regarding the colors of different parts of plants. Pleiotropy occurs when a gene affects two or more seemingly unrelated phenotypic traits.

Write the exchange reaction for the change that occurs when a potassium fertilizer is added to a humus micelle, which initially has adsorbed calcium ions on enolic groups.
The exchange reaction for the change that occurs when a potassium fertilizer is added to a humus micelle is Cation Exchange Capacity (CEC).
What is humus micelle?What are cations, which are pronounced "cat-eye-ons," first. They are positively charged ions, to put it simply. We are particularly concerned about the soil cations calcium (Ca), magnesium (Mg), potassium (K), and hydrogen (H).
The quantity of clay and/or humus in the soil affects its ability to store and exchange cations. These two negatively charged colloidal materials serve as the soil's main cation storage facility.
Sandy soils with little organic matter (OM) have a low CEC, but heavy clay soils with lots of OM have significantly higher cation-holding capacities.
Therefore, Cation Exchange Capacity is the exchange reaction for the change that happens when a potassium fertilizer is given to a humus micelle (CEC).

Types of carbohydrates
Explanation:
There are three main types of carbohydrates:
Sugars. They are also called simple carbohydrates because they are in the most basic form. ...
Starches. They are complex carbohydrates, which are made of lots of simple sugars strung together. ...
Fiber. It is also a complex carbohydrate.
Hello, see below.
So, carbohydrates can be rich in certain foods such as rice or fruit. They are poor in fish or eggs. The list goes on. Here is where we found out the types and what exactly a carbohydrate (carb. for short) is.
One of the four macromolecules, a carbohydrate or sugar, is usually the nutrient found in the greatest concentrations in a balanced diet. Glucose is the smallest kind of carbohydrate. Monosaccharides, polysaccharides, and disaccharides are the three different forms of carbohydrates. Hydrogen bonds, commonly known as hydrolosis, are present in disaccharides and polysaccharides. The hydralase enzyme shatters their connections. It is specifically carbohydrase in the case of carbs. If you look for the pattern, you'll realize that the majority of enzyme names end in "-ase."
Monosaccharides (the ‘sweet’ sugar):
In Latin, the prefix "mono" denotes "one." They are also frequently referred to as "simple sugars" since they only contain one sugar molecule. Fructose and glucose, the sugars found in sweet foods like chocolate, are examples of monosaccharides (a sugar found in many fruits). Prior to exercise, monosaccharides, particularly glucose, are frequently thought to be advantageous for athletes or to "provide a burst of energy." This is because they are tiny, which means that once you drink them, they rush to the circulation and are quickly absorbed by the body without having to be broken down first. Due to their high glucose content, most energy drinks and sports beverages.
Disaccharides:
Di is a prefix that denotes two. This is due to the fact that they have two sugar molecules joined together by hydrogen and can be converted by the enzyme hydralase, more precisely a carbohydrase, into lone monosaccharides. Examples of disaccharides include lactose, which is the sugar present in milk and is metabolized by lactase, sucrose, which is mostly found in plant stems like sugarcane and is metabolized by sucrase, and maltose (broken down by maltase, a sugar found in wheat and cornmeal).
Polysaccharides:
'Poly' is a prefix that meaning numerous. This is due to the fact that they contain more than two sugar molecules that are also hydrogen-bonded, which allows the hydralase enzymes, in particular carbohydrase and even more precisely, AMYLASE, to break them down into disaccharides and eventually monosaccharides. They are sometimes called "complex sugars." Starch, an unsweetened sugar found in savory meals like bread, pasta, and rice, is an example of a polysaccharide. It's the sugar created and stored during photosynthesis, and it's frequently found in foods related to plants, including cellulose (the sugar used to build a plant's cell wall and keep it strong) and glycogen (the equivalent of starch in humans). Instead of storing starch, we store glycogen in our liver and muscles).
Because they play a part in supplying energy, carbohydrates are an essential ingredient for a balanced diet. Despite having a larger energy content than carbs, the body gets the majority of its energy from carbohydrates since they are simpler to digest. In a balanced diet, fats should be present in moderation since they are typically stored rather than used as a source of energy. The body uses fat for relatively little energy and only starts to burn fat as a source of energy when there isn't enough carbohydrate available to do so. In addition, carbohydrates are the only fuel source used by the body while it is in a normal state.
