  • The direction of light rays changes when they reflect from a surface, travel from one transparent medium into another or travel through a medium whose composition is continuously changing. When light travels through the different medium two phenomena happen. They are reflection and refraction.

  • The name plaster of Paris came from the fact that it was first of all made by heating gypsum which was mainly found in Paris. CaSO4.2H2O → CaSO4.1/2H2O + 3/2H2O The chemical formula for the plaster of Paris is (CaSO4) H2O.

    Difference between solid liquid and gas.   #ssc #railway --> SSC Railways UPSC/PSC

  • Everything that you see around you like air, water, animals, clothes and more, is made up of matter. Also, matter refers to the collection of particles and has mass as well as occupies space. Thus, you see, there are three basic states of matter known as solid, liquid and gas. These different states of matter are because of the differences in their molecules. For instance, solids have a definite shape and size. On the other hand, liquids are flexible and will take the shape of the container they are in. Finally, gases diffuse to fill up the available volume completely. This is why it is important to know the difference between solid liquid and gas to understand them better.

  • Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.

  • Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.

    Difference between monocot and dicot.   #ssc #railway --> SSC Railways UPSC/PSC

  • Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. But, the differences start from the very beginning of the plant's life cycle: the seed. Within the seed lies the plant's embryo. Whereas monocots have one cotyledon (vein), dicots have two. This small difference at the very start of the plant's life cycle leads each plant to develop vast differences.

  • DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins. DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.

    Difference between angiosperm and gymnosperm.   #ssc #railway --> SSC Railways UPSC/PSC

  • Angiosperms and gymnosperms are the two major groups of vascular seed plants. Angiosperms, which are flowering plants, are the largest and most diverse group within the kingdom Plantae. With around 300,000 species, they represent approximately 80 percent of all the known green plants now living. Gymnosperms are a smaller, more ancient group, and it consists of plants that produce “naked seeds” (seeds that are not protected by a fruit). There are more than 1,000 species of gymnosperms still found on Earth.

  • Flora and fauna are two different terms used for describing the difference between plants and animals’ life. Flora refers to the term used to study the growth of plants living in a particular region. On the other hand, fauna refers to the study of an animal’s life, surviving in any geographical location.
