During a biology class, Benjamin, Kai, and Aria were discussing the process of digestion. They learned that when they eat a sandwich, a protein in their saliva known as salivary amylase begins to break down the starch in the bread into smaller chains of glucose. They were curious to know, what type of substance is this salivary amylase?
Hormone
Vitamin
Mineral
Enzyme
Maya, Scarlett, and Charlotte are studying DNA samples. In one of the samples, they found that 30% of the nitrogenous bases are Thymine (T). They are curious to know what percentage of the nitrogenous bases in the sample are Guanine (G).
50%
20%
30%
40%
James, Scarlett, and Daniel are studying for their biology exam. They come across a question about the composition of their hair and feathers of their pet bird. They found out that keratin is a protein found in both. Which of the following elements is most abundant in keratin?
Hydrogen
Carbon
Oxygen
Sulfur
Mia, Arjun, and Jackson are having a discussion about the high amount of the carbohydrate lactose in milk that they drink every day. They are curious to know, what is the basic structure of lactose?
two fatty acids joined to a phosphate group
A chain of amino acids in a helix (twisted) shape
a chain of alternating sugar and phosphate groups
two monosaccharides joined together
Nora, Michael, and Zoe are working on a science project about the conservation of matter. They are discussing different equations that could represent this concept. Which equation that they discussed best represents the conservation of matter?
3H2O +3CO2 -> C6H12O6 +6O2
6H2O +6CO2 -> C6H12O6 +6O2
6H2O +6CO2 -> C3H6O3 +3O2
6H2O +10CO2 -> C6H12O6 +4O2
Jackson, Aria, and Benjamin are working on a group project and need to research information. Which of the following sources should they consider as reliable for their research?
An article in a scientific journal
An educational encyclopedia
Government websites like NIH.gov
A biology textbook from 1920
Jackson, Ava, and Anika are working on a science project. They have isolated a substance that they believe could be an enzyme. To confirm their hypothesis, they decide to conduct an experiment. Which of the following experiments would best help them determine if the substance is indeed an enzyme?
Determine if the substance is a solid, liquid, or gas
Identify the color of the substance
Count the number of atoms in the substance
Check if the substance catalyzes a specific chemical reaction (speeds up or slows down a reaction)
A student is performing a chemical reaction. The mass of reactant 1 is 47 grams. The mass of reactant 2 is 18 grams. The chemical reaction produces a solid. What is the mass of the solid? Hint: Law of Conservation of Mass.
54 grams
86 grams
65 grams
