5: Three enzymes, P, Q and R, were extracted from different regions of the alimentary
canal of a mammal. The effect of pH on the activity of the enzymes was investigated at
40°C. The results are shown in Fig. 3.2.

() Explain why the investigation was carried out at 40°C.​

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

b) the inside picture would look at a very high temperature in a very low ph

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
