What Are Bryophytes? Bryophytes are a group of plant species that reproduce via spores rather than flowers or seeds. Most of bryophytes are found in damp environments and lack specialized water-conducting tissues. Examples of bryophytes include: liverworts, the mosses and hornworts. Many bryophytes usually have the following characteristics: The sporophytes of bryophytes are unbranched, producing … Read more
Sprite Sprite is a colorless, caffeine-free, lemon and lime-flavored soft drink created by Coca-Cola Company. It was first developed in 1959 as “clear Lemon Fanta’’ and was introduced in the United States under the current brand name sprite in 1961 as a competitor to 7 UP.

Endoplasmic Reticulum (ER) Cells have many organelles that work together to help them complete their life functions. One of those organelles is the endoplasmic reticulum, which is an interconnected network of membranes used to make proteins, steroids, and lipids located near the nucleus. The Endoplasmic reticulum creates, packages and secretes many of the products created by … Read more
Replication DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the basis for biological inheritance. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information or DNA as the parent … Read more
What Is Active Transport? Active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentration against the concentration gradient. Active transport uses cellular energy to move molecules against a concentration gradient. There are two types of active transport: Primary and Secondary active … Read more
Many citizens and Immigrants in the United States would often want to know the difference between Federal and State Prisons, though some of these individuals might have friends who have been to state prisons and Federal prisons, and who have narrated to them everything of how it is like to be in both prisons but … Read more
Euchromatin Euchromatin are chromosome material which does not stain strongly except during cell division. It represents the major genes and is involved in transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus (92% of the human genome is euchromatic). When observed under an optical microscope, euchromatin appears as light-colored bands. … Read more
Convex Lens If a piece of glass or other transparent material takes on the appropriate shape, it is possible that parallel incident rays would either converge to a point or appear to be diverging from a point. Therefore, a transmissive optical device that focuses or disperses a beam of light by means of refraction is … Read more
What Is Divergent Evolution? Divergent evolution is type of evolution whereby a single or same species with marginally different variations in genetic code evolve different traits and diverge into two or more different species. Divergent evolution may occur as a response to changes in abiotic factors such as change in environmental conditions or when a … Read more
The heart is a pump that supplies all tissues and organs with oxygen rich blood. The heartbeat is caused by the heart muscles relaxing and contracting. The heart contains atria and the left ventricles that determine the phases of blood pressure; that is, diastolic and systolic blood pressures. Diastolic and systolic blood pressure can simply … Read more
