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
Leaf venation refers to the arrangement and distribution of veins within a leaf. Parallel and reticulate venation are the two different types of leaf venation patterns found in plants. Venation pattern is plays a role in enhancing the transport of water, nutrients and photosynthetic products within the leaf. Vein distribution also contribute to the structural … Read more
What Are Oviparous Animals? Oviparous animals are animals that reproduce by laying eggs. Fertilization of the egg can occur internally or externally, oviparous animals always hatch their young ones outside the body. Oviparous animals can lay one or many eggs. Each egg is a gamete formed by genetic material from the female ovum and genetic … Read more
What Is Organic Chemistry? Organic chemistry is the study of structure properties, composition, reactions and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen, nitrogen, oxygen, halogens, sulfur and phosphorus. The study of structure determines their chemical composition and formula whereas the study of … Read more
