Ice is a cooler version of water.

Image Leave a comment

Water turns into ice when it cools down to zero degrees Celsius (or 32 degrees Fahrenheit). So, we can say that “ice is a cooler version of water” :D. Ice often forms on lakes, rivers, and the ocean in winters. It occurs in different forms such as frost, snow, sleet, and hail.

When the temperature of the water gets close to the freezing point (i.e. zero degrees celsius), water molecules begin to expand. In a small space, these expanding molecules can create a lot of pressure. This is why when water freezes in a crack in a rock, the ice can eventually break the rock apart (using the pressure of expanding molecules). Thus, it plays a very important role in the process of weathering.

So, now you know why we can say that ice is a cooler version of water. That is all for now and meet you in my next article. Keep Reading, Keep Exploring, and Keep Sharing your Knowledge and above all BE CURIOUS. 😉

How do lipids maintain the fluidity of the plasma membrane?

Leave a comment

The plasma membrane is an outer, thin, semi-permeable membrane that surrounds the cytoplasm and the other constituents of the cell. The Fluid Mosaic model proposed by Singer and Nicholson in 1976, describes the plasma membrane as a structure in which a mosaic of proteins is discontinuously embedded in or attached to a fluid lipid bilayer (membrane).

What is Soil? How is it formed?

Leave a comment

Every day we see small grasses, shrubs, herbs, plants, and trees around us, all this vegetation is growing in soils. We play in the ground covered with soil. The beautiful parks built in your neighborhood are built on the soil. Thus, the soil is an important part of our surrounding environment. It is an important resource that decides the diversity of life in an area. But what is Soil? can you describe it? and have you wonder how it is formed? and what are the various processes involved in soil formation?  Continue reading What is Soil? How is it formed? →

What are different factors that affect the growth of plants?

Leave a comment

All the developmental processes occurring in plants involve growth. The growth of plants involves various changes such as the addition of new cells through cell division, an increase in its size and weight, and an irreversible increase in the volume. Therefore, we can define the term growth as a permanent and irreversible change in the size of a cell, organ or whole organism usually accompanied by an increase in its dry weight.  Continue reading What are different factors that affect the growth of plants? →

How does a Tadpole change into a Frog?

Leave a comment

A freshly hatched tadpole larva has a limbless body divide into an ovoid head, a short trunk, and a slender tail. At this stage, there is no mouth and as a result, it cannot take anything from outside. Most of the nutrition is provided by the yolk material. The exchange of gases takes place in three pairs of highly vascular and feathery external gills.

How Enzymes speed up the chemical reactions?​

Leave a comment

Enzymes are complex biological molecules which catalyze or greatly speeds up the rate at which a chemical reaction will occur. They are primarily proteins, but some enzymes, called ribozymes, are made of RNA. The key concept behind the speeding up of a chemical reaction by an enzyme is that it reduces the activation energy required for a reaction. In doing so, it speeds up the reaction.  Continue reading How Enzymes speed up the chemical reactions?​ →

11 Amazing Facts about DNA You didn’t Know.

Leave a comment

DNA is the genetic material in all except certain viruses. In Prokaryotic cells, DNA occurs in the cytoplasm and is the only component of the chromosomes. Whereas, in Eukaryotic cells, DNA is largely confined to the nucleus. Do you know, A human DNA contains 3 billion chemical letters. Yes, it is true. There are several other amazing and fun facts about DNA that we don’t know.

11 Algae that are Used as Human Food.

Leave a comment

The Algae growing as planktons, benthos, epiphytes and in other common aquatic habitats provide a major source of food to small fishes, aquatic amphibians, and other animals. Since man is dependent on fishes to supplement his diet, the algae prove to be a very important indirect source of human food. The practice of direct consumption of algae as human food is also present around the world. A list of more than hundred species can be made which provide direct food to the human beings, especially to the coastal people of the world. Continue reading 11 Algae that are Used as Human Food. →

How do Auxins affect Plant growth?

Leave a comment

Auxins include all those chemical substances which promote the growth of stems or coleoptiles sections and decapitated coleoptiles, but in same concentrations are incapable of causing the growth of a whole, undamaged plant. They occur naturally in the plant parts and are also chemically synthesized. The principal naturally occurring auxin is Indole-3-Acetic Acid (IAA) and Indole-3-Butyric Acid (IBA) is a synthetic auxin. Continue reading How do Auxins affect Plant growth? →
