Formation of Conjoined Twins

By

Conjoined Twins are identical twins formed when the zygote splits but does not fully separate. Conjoined twins are classified according to the place on the body where the twins are connected. The model of the conjoined twins shown has two heads and one body. These twins are classified as dicephalus conjoined twins (twins with two […]

Formation of Identical Twins

By

Identical twins form when a zygote (egg/sperm combination) splits into two separate parts. In the diagram, 1n represents half of the chromosomes that you have in each cell. Thus, 2n represents the complete number of chromosomes. You have a total of 46 chromosome. 1n = 23 chromosomes 2n = 46 chromosomes While the two babies […]

Cohesion: Attraction Between Like Molecules

By

Cohesion is the attractive force between like molecules, such as between two water molecules or between two syrup molecules. The syrup in the photo forms a single cascading stream because the syrup molecules are attracted to each other. Discover Cohesion Yourself Wet your thumb and forefinger with water. Press these two fingers together, and then […]

Temperature vs. Kinetic Energy

By

TEMPERATURE Temperature measures how hot or cold a material is. Hot materials have a higher temperature than cold materials. In the Diagram: The contents of container A has a lower temperature than the contents of container B. I know this because the temperature reading on the thermometer in container A is lower than is the […]
