Proving Inequalities in a Triangle

The Exterior Angle Inequality Theorem which states that “ The measure of the exterior angle is greater than the measure of either remote interior angle” and the Hinge Theorem which states that “ If two sides of one triangle are congruent to two sides of another triangle, but the included angle of the first triangle […]

Phases of Meiosis

Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Mitosis

Mitosis is a process of cell duplication, in which one cell divides into two genetically identical daughter cells. In the various stages of mitosis, the cell’s chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells.

Digestive Process

The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation. The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.

Classification of Living Things

The broadest category in the Linnaean system is the kingdom. Figure above shows the Animal Kingdom because Homo sapiens belongs to that kingdom. Other kingdoms include the Plant Kingdom, Fungus Kingdom, and Protist Kingdom. Kingdoms are divided, in turn, into phyla (phylum, singular).

Phase of Meiosis

The crossing over of homologous chromosomes occurs in prophase I of meiosis. Prophase I of meiosis is characterized by the lining up of homologous chromosomes close together to form a structure known as a tetrad.

Digestive System

The breakdown of fat globules in the duodenum into the droplets, which provide a larger surface area on which the enzyme lipase can act to digest the fats into the fatty acids and glycerol is called the emulsification of fats.

Low and High Biodiversity

Threats to biodiversity differ from one ecosystem to another. In the forest ecosystem, the primary causes of forest loss are commercial exploitation and population growth (including lifestyle and consumption patterns) and the introduction of invasive alien species.
