Answer:
Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function. Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.
Explanation:
The answers to the questions required for the design experiment above are :
- If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases
- If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal.
- The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach.
- The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low).
- The Dependent variable : Number of shark attacks
- The Independent variable : The different number of elephant seals found.
- Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points.
- John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.
The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.
The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.
The Experimental group are the portion of the subjects which are subjected to the treatment condition.
The Dependent variable is the measured variable is changes as the independent variables are tweaked.
Independent variable is the predictor variable, it causes a change in the output of the dependent variable.

Answer:
Endothermic reactions absorb energy, so the sum of the energy required exceeds the amount that is released. In all types of chemical reactions, bonds are broken and reassembled to form new products.
Explanation:
Hope this helps!
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. ... Breaking chemical bonds absorb energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
