Fourth Form P&D 1 - 2020/2021 SITUATION
Bromelain is an enzyme found in pineapple which
breaks down proteins. Gelatin (jello) contains
structural proteins. When the Bromelain in pineapple
interacts with the proteins in the gelatin or Jello, the
Jello proteins are degraded and the Jello is liquified.
Plan and design an experiment to investigate the effect
of temperature on the activity of bromelain on proteins.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
