<span>pH is the measure of acidity/alkalinity of a substance. A pH of 7 is considered is neutral. Less than 7 is the acidic pH, with 1 being most acidic. Thus a vegetable with a pH of 5.3 is slightly acidic. A ph of 4.6-6.9 are called as low acidic foods. Thus, the vegetable is low-acidic.</span>
<u>Electron transport chain:</u>
An electron transport chain happens when transfer of electron happen from electron donor to electro acceptor with the help of redox reaction. This also happens with “transfer of proton” across a membrane. It creates electro chemical proton gradient. It drives the synthesis of ATP.
It stores the energy which is in the of highly strained bonds chemically. This chain molecule includes peptide enzymes which is called protein. In aerobic respiration electrons acceptance in the electrons in electron transported
I’m not sure this is right but it might be stemcells ?
Hope this helped and sorry if it’s wrong !!
Succession
It can be secondary or primary.
Primary- They start pretty much from nothing like the soil is destroyed for example a volcano eruption. Secondary- Still has soil just cutting down the grass or something like that.

But in general the Extretory aka the Urinary system gets rid of the waste.
