Down syndrome is the most common cause of mental retardation. It is caused by the presence of an extra chromosome.

They are located within the nucleus (a region […]

The decline of all major pollinators in the Northern Hemisphere, such as bats, butterflies and especially bees are likely to result in negative implications around the globe including South Africa. Bees are the most commonly chosen pollinators around the globe although there are many other capable insects. As early as the 1900’s, colony collapses have […]

Introduction For about eighty years now, people assert that life began in a primordial soup of organic molecules prior to evolving out of the ocean many years later.

Notes Ants are powerful predators: Ants may live in colonies of up to 100 thousand and like a human city they need constant supply of food. They kill large insects and carry them back to base. In one year a single colony consumes over 10 million insects. They consume more meat than lions, tigers, and […]

Homosexuality is the result of genetics and brain formation and is not a choice or effect of human nurturing. The debate of this topic has occurred for many years in many cultures. Brain formation as early as fetal growth in utero determines sexuality in proven studies. Genetic research shows that homosexuality linked through specific chromosome […]

Bilirubin, the principal pigment in bile, is derived from the breakdown of hemoglobin when aged red blood cells are phagocytized by the reticuloendothelial system, primarily in the spleen, liver and bone marrow. About 80% of bilirubin formed daily comes from the degradation of hemoglobin. The remainder comes from destruction of heme-containing proteins and catabolism of […]

Lichens are a type of mutualistic symbiosis that involve a fungus and a cyanobacterium or alga. This mutualism benefits both organisms. The photobiont, which is the cyanobacterium or alga, has chlorophyll and is capable of photosynthesis. This process allows for the production of carbohydrates that are used by both the fungi and the photobiont. The […]

Introduction Neurons are the cells that receive and transmit electrical signals. The ability of the neuron to conduct these impulses is because of an electrochemical voltage across the plasma membrane of that neuron. An action potential is an all or nothing response to a stimulus along a single axon. A compound action potential is a […]

Termites, which were previously categorized as order Isoptera in the taxonomic rank, are now recognized as the epifamily Termitoidae within the cockroach order Blattodea. Despite being commonly referred to as “white ants,” termites are not closely related to ants. Similar to ants, certain bees, and wasps, which belong to the separate order Hymenoptera, termites distribute […]

The process of prenatal development occurs in three main stages. The first two weeks after conception are known as the germinal stage; the third through the eighth week are known as the embryonic period; and the time from the ninth week until birth is known as the fetal period. The germinal stage begins with conception, […]

Cinnamon, one of the oldest known spices globally, was highly prized in ancient times and deemed more valuable than gold. It is derived from the brown bark of cinnamon trees and can be obtained as a dried tubular form called a quill or as ground powder. There are two varieties of cinnamon: Chinese and Ceylon. […]

Introduction Prenatal testing is the identification of genetic disorders, diseases, or abnormalities in a developing fetus. It focuses on conditions such as Down syndrome, Trisomy 18, and open neural tube defects. The objective of our investigation is to explore the societal impact of prenatal testing, which is a result of its development through scientific thought […]

According to Alex Gordon’s book “Animal rights: The argument of animal testing” published in 2005, Charles Darwin first utilized animal testing in 1859 to gain knowledge about the human body. Since then, […]

Introduction Albinism is the state or condition being an albino. Also it is often caused by the absence of tyrosinase, an enzyme essential for the production of cellular pigment. Albinism is a form of hypopigmentary congenital disorder, characterized by a partial hypomelanism or total lack of melanin pigment in the eyes, skin, and hair. Albinism […]

Campbell’s AP Biology Notes Chapter 48: Nervous Systems Command and Control Center The human brain contains an estimated 100 billion nerve cells, or neurons Each neuron my communicate with thousands of other neurons Functional magnetic resonance imaging (fMRI) is a technology that can reconstruct a 3-D map of brain activity The results of brain imaging […]

The lymphatic system consists of lymph vessels, lymph nodes, and lymph. These tissues and organs create a network that transports lymph throughout the body, as opposed to blood vessels. Lymph contains a high concentration of white blood cells, which assist in the body’s defense against germs. One of its main purposes is to act as […]
