Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant. In piping systems, however, there are several water quality factors working singly ...

Binary mission in prokaryotes Mitosis and Meiosis in eukaryotes Question 2 The development of embryos as well as the growth and development of bodies. Important in asexual reproduction. Question 3 The term cell cycle refers to an ordered set of events leading to cell growth and division into two daughter cells.

Question 4

Interphase is a phase of the cell cycle characterized by the absence of cell division. During this phase, the cell obtain nutrients, the organelles duplicates, protein synthesis takes place, and cells duplicate its genetic material (its chromatids).
