Description Chromatin is a complex of nucleic acids (DNA and RNA) and protein found in the eukaryotic cell nucleus whose primary function is packaging very long DNA molecules into a more compact, denser shape, which prevents the strands from becoming tangled. It also plays an important role in reinforcing the DNA during cell division, preventing … Read more
What is Anthrax Bacilli? Anthrax Bacilli or Bacillus anthracis is a spore-forming bacterium and a dangerous pathogen that causes Anthrax disease. Bacillus anthracis mainly affects livestock and wild game. Humans too can become infected through direct or indirect contact with sick animals. Usually the bacteria enter the body through a wound in the skin or … Read more

The basis of distinction include: Description, Bonding, appearance, conductivity, physical properties, chemical reaction, separation, examples, boiling and melting points. Key Differences Description Alloy: An alloy is a … Read more
The process of adsorption occurs due to presence of unbalanced or residual forces at the surface of liquid or solid phase. These unbalanced residual forces have tendency to attract and retain the molecular species with which it comes in contact with the surface. The process of adsorption involves two components adsorbent and adsorbate. Absorption according … Read more
A wet lab is a type of laboratory in which a wide range of experiments are performed, for example, titration in chemistry, diffraction of light in physics and characterization of enzymes in biology etc, all of which may sometimes involve dealing with liquid substances. Given that in this type of lab, chemicals and potential wet … Read more
What Are Vascular Plants? Vascular plants, also known as tracheophytes, from a large group of plants that are described as plants that have specialized vascular tissues (Xylem and Phloem) for conducting water, minerals and products of photosynthesis throughout the plant. The xylem, is made mostly of the structural protein lignin and dead cells, specializes in … Read more
Tissues are groups of cells that have a similar structure and act together to perform similar function. In plants, tissues are categorized into three types: vascular, ground and epidermal. In animals, there are four different types of tissues: connective, muscle, nervous and epithelial. Organs on the other hand, are structures made up of two or … Read more
Solute And Solvent Meaning A solute is defined as the substance that is dissolved in a solution. A solute can come in many forms. It can be gas, liquid or solid. The solution that breaks the solute apart and distributes the solute molecules equally thereby creating a solution that is equal throughout. Solutes in solution … Read more
A prokaryote is usually a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane bound organelle. Organisms that have prokaryotic cells are unicellular and they include archaea and bacteria. Prokaryotic cells do not have a true nucleus that contains their genetic material as eukaryotic cells do; instead they have a nucleoid region, … Read more
Plant growth regulators can be classified as both primary and secondary metabolites due to their role in plant growth and development. What are Primary Metabolites? Primary metabolites are microbial products produced continuously during the exponential phase of growth and are involved in primary metabolic processes such as respiration and photosynthesis. They include intermediates and end-products … Read more
