Explanation:
1. What was the purpose of the experiment?
Type your answer here: The purpose of this experiment is to show that a cell membrane is a type of barrier, and is permeable to some substances, but may not be permeable to all substances.
2. What were the independent, dependent, and control variables in your investigation? Describe the variables used in the part of the experiment with the eggs.
Type your answer here: Independent variable / Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. This variable is modified during the experiment to analyze how another variable responds to it. The researcher wants to study how the changes in these variables affect the dependent variable. The researcher can change these variables to see what changes it implies in an object, process, trait, or anything that depends on them.
Dependent variable / Responding variable: Its response depends on any change in the independent variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. It is usually identified by the letter Y. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. In the exposed example, the dependent variable is the egg circumference.
Constants / Controlled variables: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example the use of the lid to seal the jar and the amount and concentration of vinegar might be considered as a controlled variable. These elements are used but do not provoke any change in the size of the egg.
thats it... CAN SOMEONE ANSWER THE OTHERS?! I NEED ITT
Answer:
it was Millikan. He conducted the oil drop experiment. Thomson determined the electon charge not the quantity. Rutherford used the gold foil experiment to find positive charge and that most of the atom is empty space. Dalton proposed that matter was made of small particles called atoms but that was a concept already proposed by ancient greeks. Dalton also proposed the atomic theory.
I don't think so. "It's not a matter of pigment discrimination: Red and yellow bell peppers are essentially just green peppers that have been allowed to ripen"
