Answer:
Tube 3
Explanation:
Pancreatic amylase's optimum pH is basic, NaHCO3 is a base so it will provide the optimum pH for the enzyme to catalyse the breakdown of starch.
In tube 1 there will not be the breakdown of starch as there simply isn't any enzyme to break it down.
In Tube 2, the enzyme pancreatic amylase will most probably become denatured (loss of shape), as HCl is acidic which causes it to lose shape causing a change in the active site and will never be able to catalyse the breakdown of starch.
Hope this helps :)
Answer:
<u>subduction zones</u>
Explanation:
Image result for Where are stratovolcanoes commonly found? What type of plate boundary are they near?
Stratovolcanoes are also commonly called composite volcanoes. Mt. Fuji in Japan is an example of a stratovolcano. Stratovolcanoes are most found commonly along <u>subduction zones</u>, which are boundaries between two tectonic plates where an oceanic plate is sinking into the mantle beneath another tectonic plate.

Explanation: the first sentence is the nice loot
A proton gradient is an important part of both photosynthesis and cellular respiration because couple the favorable flow of H+ to transport specific metabolites into and out of organelles.
<h3>What is the proton gradient?</h3>
The gradient is sometimes called the proton-motive and can be thought of as a form of energy, force and force in a battery. Like other ions, protons are not able to cross directly through the phospholipid bilayer of the membrane, as the interior of the membrane is hydrophobic.
The proton gradient generated by this manipulation provided a driving force for ATP synthesis in the absence of light. This confirms the chemiosmotic theory, where a chemical potential across the membrane can provide energy for ATP synthesis.
The proton gradient produced by pumping protons during the electron transport chain is used to synthesize ATP.

D. Ribosome
Proteins are manufactured on ribosomes, which are found in the rough ER. The rough ER is called this for the rough appearance the ribosomes give it.
