Answer:
Independent Variable: different types of cancer drugs
Dependent Variable: tumor size
Constants: gender of patient, (type of cancer/tumor perhaps)
Explanation:
The independent variable will always be what modifies the dependent variable to change. In this case, it is the different types of cancer drugs modifying the size of the tumor in the patients. Dependent variables are what get changed based off of what it is being modified by. The constants should be what stays the same throughout the experiment, or else it won't be a consistent one.
Answer:
• oxygen
• nitrogen
• carbon
Explanation:
Electronegativity is a scale that measures an atom's attraction towards an electron. The more electronegative an atom is, the more it attracts an electron. Electronegativity increases as we go up and from left to right in the periodic table.
Hence, the following elements are considered to have a high level of attraction for surrounding electrons
• oxygen
• nitrogen
• carbon
Carbohydrates do not have a carbon nitrogen-bond because nitrogen is not found in this protein. So the answer is C) carbohydrate. I hope this helps.
