It is the last choice because their similar bone structures suggest they once had a common ancestor, which is why they are all mammals.
        
                    
             
        
        
        
Answer:
Rafflesia arnoldii is a tropical plant with a huge blood-red flower, which emits heat and emits the smell of decomposed meat. What use are these adaptations to this plant
Explanation:
The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.
Its possible Endothermy characteristic  is for mimicry Its releases  heat to attract  the pollinators- blowflies.The endothermic mechanism  is well pronounced during flora development: which further buttress the fact that this  is related to pollination to attract blowflies, and not to thermoregulation.
 
        
             
        
        
        
Answer:
Alcohol fermentation
Explanation:
When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration
One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH. 
Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture
This process is taken advantage of to brew beer and wine.
