Population Ecologist would often measure the number
distribution and density of the area. Trees are often measured by plots or by

Answer: just write "onion cell microscope slide experment" as the topic
Explanation: To study the structure of the onion epidermal cell, with particular emphasis on the nucleus and nucleoli.As the cells observed do not have a cell wall, nor a prominent vacuole, the cells of the specimen on the slide are animal cells.

Answer:
A decrease in pH is too acidic compared to optimum pH for amylase activity. The hydrogen ion changes amylase sites of activity and amylase activity become low. At pH 13 to 1 which is acidic, reduces the activity of amylase because the hydrogen ion changes amylase activity sites and render it's action low which will denatures amylase and make it ineffective.
Explanation:
Amylase refer to enzymes that catalyses or breakdown starch into sugars. General, enzymes are biological substances that speed up the rate of chemical reactions.
Enzymes generally are affected by pH. The most favorable pH is the optimum pH which make amylase to be effective or enzymes.
A high pH or low pH has effect on the enzymes and will reduces enzymes activities. A low pH will cause the hydrogen ion to alter the enzymes sites and reduce their activities while high pH will cause the hydroxides ion to alter the enzymes activity sites.
