Pollution and its effects

Pollution is a very important concern which cannot be neglected. Pollution comes from the word pollute which means spoiling or making the environment dirty.

Environmental pollution consists of five basic types of pollution, namely, air, water, soil, noise and light.

Air pollution is cause by the injurious smoke emitted by cars, buses, trucks, trains, and factories, namely sulphur dioxide, carbon monoxide. Air pollution effects are very severe.

Humans pollute water with large scale disposal of garbage, flowers, ashes and other household waste. Now discussing on Water pollution information, it is caused due to industrial waste products released into lakes, rivers, and other water bodies.

Noise pollution, soil pollution and light pollution too are the damaging the environment at an alarming rate. Noise pollution include aircraft noise, noise of cars, buses, and trucks, vehicle horns, loudspeakers.

Pollution is a greatest problem that the world is facing today is that of environmental pollution, increasing with every passing year and causing grave and irreparable damage to the earth.

Atom and its structure

I would say the definition of atom" as basic unit of matter; it can also called the building blocks of anything which exists in form". The central portion of an atom is known as the atomic nucleus. Atoms consist of protons, which carry positive charge, neutrons, which carry no electric charge.

 Protons are the positively charged particles, and electrons are negatively charged. Atoms make up matter and matter makes up the universe. 

Atoms get together to form molecules. Atoms are made of electrons and protons,When atoms of different elements come together, compound molecules are formed. As you might know, there are two types of compounds, ionic and covalent. The ions of ionic compounds are bound together due to the electrostatic forces between oppositely charged bodies.

Different types of pollution

Today I will write about something that is a very vital issue regarding mother earth. You all know about pollution and pollution effects such as the effect of water pollution are harming not just mother us but directly to human too. But not many of us do anything to control it.

I want to give a start and so I am acknowledging the different types of pollution here itself:

• Air pollution.
• Water pollution.
• Noise pollution.
• Soil pollution.
• Thermal pollution.
I have just given a start; you all acknowledge the causes and start controlling these causes in order to save earth and save human kind.

Do share with me your experiences and suggestions.

Physical properties of Oxygen

Writing educating blogs is really a pleasurable experience. It not just allows me to help you but at the same time it helps me to refresh my own memories. We all are familiar of the gases such as Oxygen, Nitrogen, Carbon di oxide and so on and also we know about their respective physical quantities or properties. Today’s let’s learn the physical properties of oxygen and their physical structure.

The following are the physical properties of oxygen:

• Oxygen is colorless, odorless and tasteless in normal conditions.
• It is heavier than air.
• It is soluble in water.
• It is paramagnetic to nature
• It liquefies to give pale blue liquid.
I am sure you got a quality learning through this writing and I am sure you will post me your feedbacks.

Fish life Cycle

In this post we will learn about fish , and a basic fish life cycle.Fish live their entire life in water.

  

A typical fish life cycle starts with an egg. The egg hatches into what is called a yolk sac fry - a larval stage where the fish has an attached yolk that provides it with nourishment for its first week or two.

The true larval stage begins when the fish has absorbed the yolk and starts feeding for it self.

When the fish gets bigger and looks very much like an adult, it is considered a juvenile.

Once the fish matures and can reproduce and lay eggs, it becomes an adult. 

I guess this post was useful, please send me your suggestions and comments. In the next post we will learn about fish respiratory system in detail.

Types of Enzymes

In this post we will learn about the types of enzymes and their functions.

We have three main categories of enzymes:

1)      Metabolic Enzymes

2)      Digestive Enzymes

3)      Food Enzymes

Metabolic Enzymes: These metabolic enzymes are responsible for the smooth running of the body, tissues and organs. They help us in the overall growth of cells , repair and maintenance of the body’s organs and tissues.

Digestive Enzymes: Digestive enzymes are responsible in the digestion of food and the absorption and delivery of nutrients throughout the body.. Each enzyme is specific to a particular compound which it breaks or synthesizes

Food Enzymes: Food enzymes are derived solely from raw fruits, vegetables, and supplemental sources. Like digestive enzymes, they enable the body to digest the food by breaking down the various nutrients -- proteins, fats, carbohydrates, and vitamins and minerals - into smallest compounds that the body can absorb. They are absolutely essential in maintaining optimal health.

States of Water

There are 3 states of water. They are solid, liquid, and Gas. As we know there are various liquid solutions, which are formed by combining two liquids.

Gas to Liquid:  When the gas changes to liquid , we have a process of condensation. So, in this process gas cools and loses energy. So, the water particles are forced to change the state, from gas to a liquid.

Liquid to Solid: When a liquid changes to solid, the process is called freezing. When the liquid cools below the freezing point and loses energy. Then the particles are forced to change state from liquid to a solid.

Solid to Gas: When a solid changes directly to a gas, the process is names Sublimation.

Liquid to Gas:  This is a process where liquid changes into gas and the process is called evaporation. 

 I hope we have understood the different states of water. for more science help, please look into my other posts on science.
