Answer:
a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.
The species of plankton found in sediments and their isotope ratios can show the temperature of the overlying waters when the sediments were deposited.
The bacteria can move by the means of swimming, pushing, twitching and gliding. They can also move randomly. They do not need any specific structures for their movements. Taxis, pilli, flagella and actin helps in their movement. The bacterial cell have the ability to move via taxis and can also use their pilli in order to move together. That is the reason the ETPUM on the Lycra-sealed slide is redistributed. The bacterial cells using taxis can gain energy from the polyurethane.
