Answer: Hypoxia
Explanation: hypoxia induces the production of erythropoietin, which is a hormome produced by the kidneys to help increase the productiom of red blood cells in the body. In Jessica's case, she might be experiencing this due to a change in ultitide whereby her body needs more oxygen than it originally gets (crllular hypoxis), therefore, her body signals for more red blood cell production. The erythropoietin will then be secreted and more red blood cells will be formed by the bone marrow through the hormonal action.

Carbon and hydrogen. 
The simplest group of organic molecules are the alkanes which have only these 2 elements. Eg methane, CH4. 
        
                    
             
        
        
        
Explanation:
John Dalton proposed the theory of matter which is popularly known as the Dalton's atomic theory. In the atomic theory, Dalton identified from his experiments on gases that every matter is made up of small indivisible particles called atoms. These atoms are the smallest fractions of a matter. 
-  All the atoms of an element are all alike. 
- Compounds form from atoms by simple whole number combinations alone. 
- Chemical combination of atoms involves the rearrangement of reactants. 
Therefore, using these clues you should be able to answer the question.
