What is E-commerce?

What is E-commerce? E-commerce (Electronic commerce or EC) is the buying and selling of goods and services or transmitting funds or data over an electronic network, primarily the internet. These business transactions occur either business to business, business to consumer, consumer to consumer, or consumer to business. This thesis is concerned with the impact of electronic commerce on international tax laws, specifically source-based taxation. Before looking specifically at the arguments and propositions to be advanced by the thesis, it is both instructive and necessary, to begin with, a discussion of what is meant by ‘electronic commerce’. Discussions relating to electronic commerce normally begin with a pronouncement that it represents a fundamental and revolutionary development in communications that is likely to dramatically change the way business is conducted. This is usually followed by highly variable, speculative, and often mind-numbing estimates of the expected growth of th

What are the function of blood?

Functions of blood The digested food absorbed by the wall of the intestine is transported to the cells by the blood. The excretory materials produced within the cells are carried to the excretory organs by the blood. Hemoglobin of erythrocytes of blood accepts oxygen from the lung and carry it to the cells as oxy-hemoglobin. It also carries the carbon dioxide produced in cellular respiration to the lung from where it goes out of the body. The hormones secreted by different endocrine glands are carried to different parts of the body by the blood. The white blood cells engulf the parasite entering the body by the process of phagocytosis. It also produces antigens that act as the preventives against diseases and thus increase body resistance. Body temperature is also regulated by the blood. The thrombocytes present in the blood, when coming in contact with free oxygen, helps blood coagulation. Thus the thrombocytes stop bleeding from the wounds.  Read More The position and Functions of wo

What is Food Web?

Image
In nature, most food chains connect other chains. The complex food chain of more than one is known as a food web. In most cases, it is found that the same consumer can be placed in different trophic levels. This way some food chains collectively may form a net or web like structure. It is called a food web. So, food chains are not distinct. They are interrelated with each other and form a food web.  Read More Why Adulterant food is the barrier to sound health? What are the producers?

What is food chain?

Staring from plant source the transfer of energy by eating and being eaten up by different animals, is known as food chain.  Read More Why Adulterant food is the barrer of sound health? What is producers? What are food preservatives? What is tertiary consumer?

What is cell?

The structural and functional unit of the living body is the cell. Loey and Sekevitz defined the cell as - surrounded by a selectively permeable membrane, is a unit of living activities, which exactly duplicate itself without any different living medium.  Read More Why Adulterant food is the barrer of sound health?

The structure of bast fiber?

They are very elongated, slender, thick-walled and both the ends of them are pointed, but sometimes may be rounded. In their walls, they have pores called pits. These long cells have arranged an end to end with others.

Position of wood fibers They are present in the xylem throughout dicots. Function of wood fibers The functions of wood fibers are- Transportation of water and minerals Storage of food Giving mechanical support Giving strength of plants

Why the flowers and fruits are coloured?

Due to chromoplast the flowers and fruits are colored. Though the chromoplasts are colored, they are not green. The phycoerythetic pigment xanthophylls, carotene, phycoerythrin, phycocyanin etc. are present in them, and so some of them are yellow, some others are blue and red. The flowers, leaves, and other parts of a plat assume their attractive colorful appearances from the mixture of those pigments.  Read More Why Adulterant food is the barrer of sound health?

How is the structure of stone cell?

These cells compared with most fibers are shorter, isodiametric, or sometimes long and star-shaped. Their secondary cell walls are very durable, thick, and lignified. The walls of the cells are pitted. 

What is the characteristics of eukaryotic cell?

The characteristics of a eukaryotic cell are - Nucleus is well structured. Nuclear membrane and nucleolus are well organized. Chromosomes are organized with protein and other components. Along with the ribosome, other cell organelles are present in the cell. 

Where the sclereids tissues are found?

In the cortex, fruits, and seed shells of gymnosperm and fruits and seed shells of gymnosperm and dicot plants, sclerites are found. In the petioles of leaves, they may be present in cluster form associated with epidermis, xylem, and phloem.  Read More Why Adulterant food is the barrer of sound health? What is producers?

What are the function of cell wall?

The functions of the cell wall are to protect a cell form all external injuries. It gives a cell its rigidity. The cell wall retains the shape and size of a cell. For exchanging materials with the adjacent cell. Plasmodesmata are formed in a cell wall. The cell wall controls the movement of water and minerals. 

Primordial germ cells are diploid, but why the germ cells are haploid?

Primordial germ cells are diploid (2n) and in the process of meiosis cell division, they create female and male gamete cells. In meiosis cell division, the nucleus is divided twice but the chromosomes are divided only once. As a result, the daughter cells get half of the number of chromosomes of the mother cell. This is why primordial or mother germ cells are diploid and gamete or germ cells are haploid. 

Why do the cells of multicellular organism are called eukaryotic cell?

Eukaryotic cells contain a well-developed nucleus, which means nuclear materials are well arranged and surrounded by a nuclear membrane. Chromosomes in this cell contain DNA, protein, histone, and other components. The cells of a multicellular organism have these features and this is why they are named as eukaryotic cells. 

What does eukaryotic cell mean?

Cells that contain a well-developed nucleus, which means nuclear materials are well arranged and surrounded by a nuclear membrane, are known as eukaryotic cells. Eukaryotic cells are of two types somatic cell and germ cell. Ribosomes and other organelles are present in this cell. Most of the animal cells are eukaryotic.
