Answer:
<em>C)  Eat locally-produced and organic food; cur meat and dairy consumption.</em>
Explanation:
Eating organic food will be of no help because humans do not usually use forest trees as food resources. And hence, it will be of no help to stop the carbon dioxide emissions. Hence, option C will be of no help.
The consumption of green products will lead to lesser production of carbon dioxide and hence can be helpful. Using alternate energy sources which are not carbon based will also help to reduce the amount of carbon dioxide. If lands are restored then, these trees will not change over time. Hence, option A, B and D are helpful for  no substantial change in the tree species over time. 
 
        
                    
             
        
        
        
Answer: diaphragm
Explanation:
The diaphragm separates the thoracic cavity from the abdominal and pelvic cavity.
The diaphragm is a sheet of internal skeletal muscle located below the thoracic cavity that houses the heart and lungs. Below the diaphragm is the abdominal cavity.
The diaphragm plays an essential function for respiration. When the diaphragm contracts, the volume of the thoracic cavity increases so that air is drawn into the lungs.
        
             
        
        
        
Answer:
Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. .
 
        
                    
             
        
        
        
Answer;
C. His mother carried at least one allele for that trait
Explanation;
-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father. 
-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.
-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.
 
        
                    
             
        
        
        
Basically, the P-P chain turns 4 protons into: 1 neutrino, 1 gamma ray, 1 positron, 1 helium nucleus. 
A gamma ray = energy. 
The chain converts hydrogen into helium and makes energy. 
This is all occurring through fusion reactions where 2 protons basically smash into each other. But, it could also be e.g. a proton smashing with a deuterium nucleus. Or, other nuclei smashing together to make something else.
Hope this helps!
