Explanation:

Assuming the radius of the cell is given as r, to calculate the volume and surface area of a cell, the formula below is used;

Cells are the basic structural and functional unit of life.

Cells are what all living organisms are made up of.

Organisms that are made up of only one cell are said to be unicellular whereas organisms that are composed of multiple cells are said to be multi-cellular.

To calculate the volume and surface area of a cell, it is assumed that the cell is a sphere. This is because most cells when placed in a liquid medium or suspension, they exert equal forces in all directions, which results in the cells assuming a spherical shape.

To measure the radius of the cell, the cell is placed in a suspension and then viewed through a microscope at a know magnification. The radius of the cell is then taken.

The radius of the cell obtained is then used to calculate the volume and surface area of the cell.

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.

Answer: Urban sprawls are unsustainable.

Explanation: Urban environmental sustainability encourages the revitalization and transition of urban areas and cities to improve liveability, promote innovation and reduce environmental impacts while maximizing economic and social co-benefits. Urban systems are inherently complex. Urban sprawl has significant environmental, economic and social consequences. It leads to higher emissions from road transport and loss of open space and environmental amenities.

Answer: No

Explanation:

Urban sprawl is the expansion that refers to a complex pattern of land use, transportation, and social and economic development usually as a direct effect of population growth on a national level. Urban sprawl is not sustainable for the environment because it creates an increase in water and car usage increasing air pollution, and creates a loss of agriculture capacity of the land. This increase in air pollution and loss of agriculture and woodlands leaves no plants able to create oxygen to sustain a thriving ecosystem. While some may argue that Urban sprawl helps create a better economy, better employment, and better living conditions, in terms of Biology, Urban sprawl is a leading cause of the destruction of our ecosystems.

The way that the respiratory and circulatory systems change throughout the day is that they work  together to supply the body with oxygen, the respiratory system collaborates directly with the circulatory system to do the above.

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.

Note that in the process of their collaboration during the day, Inhaled oxygen travels into blood vessels where it is subsequently circulated to tissues and cells through the body's circulatory system.

Answer:

the right answer is 10

Explanation:

While bases take protons in processes, acids donate protons (H+). While bases have a pH of 7 or higher, acids have a pH of 7.

While bases take protons in processes, acids donate protons (H+). While bases have a pH of 7 or higher, acids have a pH of 7. Acids release H+ ions while bases release -OH when they separate in water. While acids render litmus paper red, bases turn it blue.

1) In Experiment 1, the color of the solution changes from light (suggesting base) to dark when the acid is introduced (suggesting acid). As a result, adding the acid in this instance produced an ACIDIC solution.

2) In Experiment 2, the reverse is accurate. The hue stays light even after the addition of the acid (suggesting base). The outcome in this instance is BASIC as a result.

3) When the acid is given to the base to buffer it, this is Experiment 2. As you recall, a buffer solution is one that doesn't alter in pH when an acid or basic is introduced. We may infer that the addition of the acid in Experiment 2 was made to produce a buffer solution because it was done so the pH didn't fluctuate as much as it did in Experiment 1.

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.

Biology is the study of living organisms, both extant and hypothetical. Because information in other animals' genetic make-up may contain information about our own, it is crucial to research it. Since an amoeba has just one cell, it is an organism.

When two atoms exchange or contribute their electrons, an ionic connection is created. Atoms can be attracted to one another by van der Waals forces. The electrons are always drawn to both atoms in an ionic connection equally. The process by which atoms or groups of atoms in the compounds are restructured into new substances is known as a chemical reaction.
