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.

Active and passive transport of solutes across a membrane typically differ in which of the following ways?
a.Active transport is usually down the concentration gradient of the solute, whereas passive transport is always against the concentration gradient of the solute.
b.Active transport always involves the utilization of cellular energy, whereas passive transport does not requires cellular energy.
c.Active transport is always faster than passive transport.
d.Active transport uses protein carriers, whereas passive transport uses carbohydrate carriers.
e.Active transport is used for ions, passive transport is used for uncharged solutes
Active transport always involves the utilization of cellular energy, whereas passive transport does not requires cellular energy.
Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Passive mechanisms like diffusion use no energy, while active transport requires energy to get done. key differences also include Passive transport moves molecules with the concentration gradient (high to low), while active transport moves molecules against the concentration gradient (Low to High).

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.

What impact do out respiratory and cardiovascular systems have?Poor food and lifestyle choices might make it harder for the respiratory system to work well. For instance, smoking can harm the tissues and cells in the lungs, which can make it exceedingly challenging for the lungs to release carbon dioxide and deliver oxygen to the body.
