The three types of fiber-optic cables which can be found online include single mode, multimode, and the plastic optical fiber.

A fiber-optic cable is also known as the optical-fiber cable. It is an assembly which is very similar to an electrical cable however, it contains one or more different optical fibers which are used to carry the light energy.

Three major types of fiber-optic cables which could be found online are single mode, multimode, and the plastic optical fiber (POF). The multimode optical fiber or the OFC is the cable which is capable of carrying multiple light rays or modes together at the same time as it has varying optical properties at the core of the cable. Single-mode fiber has a much smaller core size which is about 9 microns in length, it is smaller than that of other cable sizes.

Answer:Single-mode cables include one glass strand (the core), surrounded by three layers of other material (the cladding, the buffer, and the jacket). They are relatively more expensive than other cables. Single-mode cables can transmit data at fast speeds over long distances (up to 62 miles) and offer higher bandwidths.

Multi-mode cables have more than one strand and transmit light along many paths. They support very fast speeds of between 10 Mbps to 10 Gbps over short distances (2,000 and 1,000 feet, respectively). Although these cables can transmit data over short distances, they will distort data over long distances.

Plastic optical fiber cables consist of plastic fibers instead of glass fibers. They are cheaper than glass optical fiber cables. They are similar to multi-mode cables; however, they are only reliable over short distances.

The pH changes in the food vacuoles due to the increase in the acidity of the fluid, because of respiration process in the ingested organisms.

In chemistry, the pH scale is used to define the acidity or basicity of an aqueous solution. Historically, pH stood for "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.

The respiration of the organisms that have been consumed, the chemical changes brought on by their death, the disintegration of the consumed plasmalemma, the impermeability of the membrane surrounding the vacuoles to acids, and the diffusion of fluid from the vacuoles are all likely to be to blame for the increase in acidity of the fluid in the food vacuoles.

It is easier to conduct than the wet-mount but is only good for short-term observation because the wet-mount tends to dry out fast under the heat of the microscope light. The hanging-drop approach is more difficult, but it enables longer-term observation and more accurate motility monitoring.

Suspending living microorganisms in a liquid (such as broth, water, or salt) and creating a "hanging-drop" or straightforward "wet mount" are the two easiest ways to examine them. The cover glass supports a suspended drop on the slide, which has a concave well ground into its surface. The drop dangles from the cover glass when it is placed upside down over the slide's well and concave concavity. The technique primarily assesses an organism's motility, but it also enables a clear picture of the natural patterns of cell groups and individual cell form. Because the hanging-drop preparations take some time to complete, the drop does not dry out quickly.

What is Photosynthesis?

The word photosynthesis can be separated to make two smaller words:

Plants need food but they do not have to wait on people or animals to provide for them. Most plants are able to make their own food whenever they need it. This is done using light and the process is called photosynthesis.

Photosynthesis is the process by which plants make their own food. We will add more details to this definition after making a few things clear as you will see below

To make food plants need:

Let’s take a look at how these are collected by plants.

Photosynthesis takes place in the leaves of plants. The leaves are made up of very small cells. Inside these cells are tiny structures called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color.

Some of the glucose is used to provide energy for the growth and development of plants while the rest is stored in leaves, roots or fruits for later use by plants.

Here is the process in greater detail:

Photosynthesis occurs in two stages commonly known as Light dependent Reactions and the Calvin Cycle.

Light dependent Reactions

Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available. During these reactions light energy is converted to chemical energy.

The Calvin Cycle

The Calvin Cycle reactions occur in the stroma of the chloroplasts. Although these reactions can take place without light, the process requires ATP and NADPH which were created using light in the first stage. Carbon dioxide and energy from ATP along with NADPH are used to form glucose.

What have you learned so far?

You already know that plants need carbon dioxide, waterand sunlight to make their food. You also know that the food they make is called glucose. In addition to glucose, plants also produce oxygen.

The equation below is the same as the one above but it shows the chemical formula for carbon dioxide, water, glucose and oxygen.

Now back to the definition… Earlier you learned that photosynthesis is the process by which plants make their own food. Now that we know what plants need to make food, we can add that information as shown below.

Photosynthesis is the process by which plants make their own food using carbon dioxide, water and sunlight

Why is Photosynthesis Important?

Photosynthesis is important because it provides two main things:

Some of the glucose that plants produce during photosynthesis is stored in fruits and roots. This is why we are able to eat carrots, potatoes, apples, water melons and all the others. These foods provide energy for humans and animals.

Oxygen that is produced during photosynthesis is released into the atmosphere. This oxygen is what we breathe and we cannot live without it.

While it is important that photosynthesis provides food and oxygen, its impact on our daily lives is far more extensive. Photosynthesis is so essential to life on earth that most living organisms, including humans, cannot survive without it.

All of our energy for growth, development and physical activity comes from eating food from plants and animals. Animals obtain energy from eating plants. Plants obtain energy from glucose made during photosynthesis.

Our major sources of energy such as natural gas, coal and oil were made millions of years ago from the remains of dead plants and animals which we already know got their energy from photosynthesis.

Photosynthesis is also responsible for balancing oxygen and carbon dioxide levels in the atmosphere. Plants absorb carbon dioxide from the air and release oxygen during the process of photosynthesis.

Higher specific heat of water exhibits its role in winter by collecting heat during day and warms up at night. Whereas, during summer the water evaporates and keep relatively low temperature in surroundings.

The term "heat capacity" refers to the amount of energy required to increase or lower a material's temperature. A greater energy variation is required to change the temperature of an object with a high specific heat capacity compared to one with a low specific heat capacity.

The capability of water to transfer energy during times of high temperature and release it during times of low temperature is facilitated by its specific heat, which helps to keep the Earth's temperature. A substance's specific heat is the amount of heat required to raise a mass of that substance's temperature by one degree Celsius. Water can keep heat longer than many other substances due to the hydrogen bonds that occur between its molecules. The hydrogen bonds between water continue to break and reform as the temperature rises, allowing the system's overall temperature to stay stable despite the introduction of more energy.

The strategy that involves the use of nutrients to directly encourage the growth of existing healthy biota is A Prebiotics.

Prebiotics are non-digestible food ingredients that are fermented by the gut microbiota and promote the growth and activity of beneficial bacteria in the gut. These ingredients, such as fiber and certain sugars, provide nourishment to the healthy gut microbes and enhance their ability to colonize the gut and outcompete harmful bacteria.

Probiotics, on the other hand, are live microorganisms that are ingested with the goal of colonizing the gut and providing health benefits. Probiotics can be found in fermented foods like yogurt and kefir, or in supplement form.

Bacteriophage therapy is the use of bacteriophages, which are viruses that specifically target and kill bacteria, to treat bacterial infections. This strategy is different from prebiotics as it involves the use of microorganisms to directly target harmful bacteria rather than encouraging the growth of existing healthy biota.

Fecal transplantation involves the transfer of feces from a healthy donor to a recipient with the goal of introducing a diverse population of healthy gut microbes and restoring the balance of the gut microbiota. This strategy is similar to prebiotics in that it involves the introduction of beneficial bacteria, but it is a more direct and invasive approach.

In conclusion, prebiotics is the strategy that involves the use of nutrients to directly encourage the growth of existing healthy biota in the gut.
