In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species

A. Fermentation Lab- The basic process Prepared 3 beakers with contents listed below. ( a. Beaker 1: glucose only b. Beaker 2: Starch only c. Beaker 3: Starch + amylase). Poured contents of each beaker into its respective fermentation tube‚ ensuring the tail portion of the tube was filled with liquid. Placed tubes in an incubator at 37 degrees‚ measuring distance between tip of tube tail to fluid level at 20‚ 40‚ and 60 minute intervals. Calculated gas volume using this distance along with radius

aerobic respiration in plants and animals e.g. germinating seeds and mealworms Bio Experiment : Comparing Rate of respiration in mealworms at different temperatures? Mealworms are cold-blooded animals and are unable to maintain a constant core temperature‚ hence respiration would therefore change with temperature. As glucose is oxidised‚ oxygen is used up and carbon dioxide and heat energy is produced. Increment in temperature / production of CO2 or O2 consumption would hence be good indicators

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration
