Respiration

Q. Respiration in insects is called direct because:

1. $\text{The cells exchange}{O}_2/C{O}_2\text{directly with the air in the tubes}$
2. $\text{The tissues exchange}{O}_2/C{O}_2\text{directly with coelomic fluid}$
3. $\text{The tissues exchange}{O}_2/C{O}_2\text{directly with the air outside through body surface}$
4. $\text{Tracheal tubes exchange}{O}_2/C{O}_2\text{directly with the haemocoel which then exchange with tissues}$

Q. In batch fermentation

1. substrates are added to the system all at once and run until the product is harvested
2. nutrients are continuously fed into the reactor and the product is removed during the run
3. new batches of micro-organisms are screened for increased yield
4. species of the micro-organism used, is changed at regular intervals
