A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

Haemophilia is an inherited bleeding disorder where the blood doesn't clot properly. It is caused when blood does not have enough clotting factor.

The main treatment for hemophilia is called replacement therapy. Concentrates of clotting factor VIII (for hemophilia A) or clotting factor IX (for hemophilia B) are slowly dripped or injected into a vein. These infusions help replace the clotting factor that's missing or low.

Cellular respiration can be broken down into three main steps:

1. Glycolysis,

2. The Kreb's cycle (The citric acid cycle), and

3. Electron Transport Chain.

Chloroplasts contains chlorophyll, the green substance in plants that allows them to create food from carbon dioxide and water called as photosynthesis.

A gametes are haploid cells as they have only one set of chromosomes. Meiosis is a process of cellular reproduction in which both male and female gametes are formed. During meiosis, the DNA is only replicated or copied one time.

ATP - Adinosine Triphosphate is the compound that directly provides energy for cellular work.
