Compose a valid conclusion for: After a 3 hour continuous usage of batteries in high drainage devices. Duracell batteries retained 35% of its voltage charge and Energizer batteries retained only 20% charge.
What is Duracell are better batteries because they retain 15% more charge than Energizer at the same usage.

A mad scientist wants to see if the strain for a vampire virus that he created will work and cause an epidemic. He tests his strain on mice. The strain is what influences whether or not his mice will become vampire mice and become blood thirsty animals. He injects 7 mice with different dilutions of the strain in saline solution. The 4 mice with the strongest dosage of the strain become vampires. In order: name the dependent and independent variable in this experiment.
What are if mice become vampires and the strain?

5 Plants were placed in 5 different chambers with 5 different color lights because a scientist wanted to determine how color light affected the growth of plants. The intensity of all lights were kept the same as well as the amount of water and soil in each plot. name the independent variable in this experimental group.
What is plant growth?

A new drug is to be tested for a type of skin condition. 300 people in group A receive a cream with actual medication for the condition in it and 210 people in group B receive standard lotion in a prescription container. Each group applies the skin cream for 30 days, 3 times a day. The critical error in this experiment is.
What is lack of balance in control and experimental group?

People with bee sting allergies can have deadly allergic reactions when stung! Epinephrine pens (epi pens) are often carried with people who experience allergic reactions because it helps them to regain breathing and heart rate. To further prove this point, 500 people with allergies were given epi pens and another 500 with the same condition were given fake epi pens filled with water and exposed to bees. State why the scientist who attempts this experiment should be fired and disciplined.
What is because this action is completely unethical!
