Write simple instructions on 'How to make Oral Saline'.

To make Oral Saline is an easy task. First, I have to take one and a half liters of water. Then, I must boil it for at least half an hour. Then, it will be one liter and then I have to pour it into a clean pot. I let the water cool down completely. Then, I wash my hand in clean water, and take a handful of sugar and drop it into the cool water. After that, I must add one pinch of salt to three fingers. finally, I have to stir the compound well. When the salt and sugar dissolve completely the Oral Saline is made. This is a life-saving drug for cholera and diarrhea patients for those who suffer from dehydration.

Finance and Business Finance

Finance and Business Finance With the gradual progress of society & civilization and the development of science and technology, the scope of trade and commerce has also increased. Hence, the product-market has to cope with diverse competitions. To make profit in this competition, a businessman has to utilize his capital efficiently through proper planning so that the cost of production or selling could be kept minimum. Hence, a business firm can maximize its profit. For that purpose, every business firm collects its necessary fund for investment from the most desirable sources, and invests it in the most suitable project by analyzing various information of the product-market. This creates inflows and outflows of fund in the business. Finance regulates these flows of fund nicely. Different principles of finance are used in this process of regulation. Financial Management helps a businessman to earn enough profit from investing even a small amount of capital. Now-a-days finance is no

The Importance of Information and Communication Technology

The Importance of Information and Communication Technology Information and Communication Technology (ICT) refers to the use of technology to manage and exchange information. In the modern world, ICT has become an indispensable tool for individuals, businesses, and organizations alike. Its impact on society has been significant, leading to the creation of new opportunities, improved efficiency, and increased connectivity. One of the key benefits of ICT is the increase in efficiency that it has brought about. With the help of technology, information can be processed, analyzed, and shared more quickly and accurately than ever before. This has led to improved productivity and a more streamlined workflow. For example, businesses are now able to automate repetitive tasks and focus on more important tasks, leading to more efficient use of time and resources. Additionally, ICT has enabled the creation of virtual work environments, which has allowed individuals to work remotely and busines

Learning Outcomes  👉 What is biodiversity  👉 Origin of biodiversity  👉 Nature of biodiversity  👉 Interrelationships of organisms  👉 How to measure biodiversity  👉 Biodiversity of Bangladesh  👉 Risks and remedies of biodiversity  What is Biodiversity? The term biodiversity describes the great variety of life on Earth. Biodiversity refers to the variety of living things, including plants, animals, and microorganisms. We don't know for sure exactly how many different organisms there are on Earth. However, scientists estimate that there are about 8-14 million (80 to 140 lakh) different species of organisms on this Earth. Some believe that the number is higher. But whatever the number, most of these organisms are unknown to us. Only 1.2 million (12 lakh) species have been identified and described so far, most of which are insects. This means that billions of other organisms are still mysterious and unknown to us. Origin of Biodiversity The unique characteristics of all sp

Lessons on Life

  Biology Chapter - 1: Lessons on Life 👉   All Chapter Contents   👈   1.1  Concept of Biology What are living things? Living things, also known as organisms, are entities that have the ability to carry out fundamental life processes such as growth, reproduction, metabolism, and response to stimuli. Living things are characterized by their organization, complexity, and ability to maintain homeostasis, which is the process of maintaining a stable internal environment despite changes in the external environment. Living things are diverse and can be found in various forms, ranging from single-celled organisms like bacteria and protists to complex multicellular organisms like plants, animals, and fungi. They interact with their environment, including other living and non-living things, and play a critical role in the maintenance of ecological balance and the continuation of life on Earth. What are non-living things? Non-living things, also known as inanimate objects, are entities that l

What is biological coin?

What is a biological coin? ATP is called the energy coin of the cell because it can store energy and can supply that energy to the cell's demand. ATP (Adenosine triphosphate) is known as ' biological currency ' or energy coin, where energy is stored and can be used whenever the cell demands it.  Energy is released from the photosynthesis process to generate foods through respiration. Usually, this energy is stored within ATP in the bond of the terminal phosphate group. When this bond is broken, energy is released, which can be used in different physiochemical reactions. The basic mechanism of production and utilization of energy in the body of a living organism is its bio-energy. This is not very different from the definition of energy given in physics. The energy we get from making and breaking chemical bonds in the molecules found in biological organisms is called by this name. Living organisms continuously collect energy from the environment, transform them one from

Main components of computer systems

Image
A typical computer system is made up of hardware and software. The figure shows an example of a computer system consisting of input devices, output devices, and secondary storage. These will be discussed in more detail in Chapter 2, but examples include: Input devices: keyboard, mouse Output devices: monitor, printer Secondary storage devices: DVD R/W drive, removable hard drive. However, one part of the computer system has not yet been mentioned. This is shown as the ‘Processor and internal memory devices’ in the diagram – this consists of four key components called the central processing unit (CPU), internal hard disk, random access memory (RAM), and read-only memory (ROM). The central processing unit (CPU) is the part of the computer which interprets and executes commands from the computer hardware and software. CPUs used to be made up of discrete components and numerous small integrated circuits, which were combined together on one or more circuit board/s. However, due to modern
