Answer:
Oxygen
Explanation:
Cellular respiration is the process whereby living organisms synthesize energy in form of ATP. However, it can either be aerobic or anaerobic depending on whether it occurs with or without oxygen. Aerobic respiration occurs in the presence of oxygen. 
The aerobic cellular respiration is further divided into glycolysis, Krebs cycle and oxidative phosphorylation. The oxidative reactions used by aerobic bacteria to generate ATP use OXYGEN as a terminal or final electron acceptor.
 
        
             
        
        
        
This is called <span>thigmotropism
It comes from ancient Greek and basically means to touch in a certain direction. They don't, however, only react to touch; they react to things like wind too in order to latch and not be separated when there's wind blowing on them. </span>
        
             
        
        
        
Answer:
Corpus callosum
Explanation:
Corpus callosum is the red part of the brain that has a “C” shape. The corpus callosum, which is made up of over 200 million of neural fibers, links both hemispheres of the brain (the left and right brain) together, which allows for coordination and complex communication between both in order for the brain to function properly. 
This structure usually starts forming about 12 weeks after conception of a child, and continues to develop up to about 12 years of age of the child.  
The main function of the corpus callosum is the ensuring of uninterrupted flow of information, and the integration of complex information and tasks such as motor, sensory and cognitive functions between both hemispheres of the brain.
 
        
             
        
        
        
Answer:
The process depicted in the diagram above is explained below in complete details.
Explanation:
1 asexual generation
2. cytokinesis
3. karyokinesis 
4.fission
(a) Amoeba
(b) in repetitious fission many elements modifications to offspring ( plasmodium ( while in amoeba only individual sections to create two separate daughter cell
(c) asexual reproduction
ii in leishmania you can totally cut three sections and it changes to a new organism and in amoeba, it can be cut wherever.
