The skeletal system, nervous system, and digestive system.
The skeletal system is used to move your mouth and jaw it is also used to help you chew.
The nervous system let you taste and smell the food. This is because it sends signals to your brain to allow you to taste and smell the food.
The digestive system produces saliva and allows the food to be processed into energy.
the chemical bonds were broken when they were digested and the chemical composition of the food was changed
Answer:
Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships.
Explanation:
Basically it is a hypothesis from before hypothesis actually were called hypothesis
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.

C. exocytosis
just think "exo" sounds like "exit". diffusion is mostly gases, endocytosis is coming in, and osmosis is water
