This is the substance that bacteria grow on inside a petri dish.
What is agar?
When designing an experiment, scientists will test a relationship between a “cause” and an “effect.” The “cause” is known as the
What is the independent variable?
The identity of an element is determined by these particles.
What are the number of protons?
Two atoms of hydrogen are bonded to 1 atom of oxygen by these strong bonds to make a water molecule.
What are covalent bonds?
The majority of the cell membrane's bilayer is made up of these macromolecules.
What are lipids?
This is why prepared petri dishes should be stored upside down.
What is to prevent contamination with condensation?
This is described as how close your measurement is to the correct value.
What is accuracy?
The numbers of these are equal making the atom electrically neutral.
What are protons and electrons?
Water molecules are bonded together by these weak bonds.
What are hydrogen bonds?
This is the order in which each macromolecule is consumed by the body for energy.
What is (1) carbohydrates, (2) lipids, and (3) proteins?
The fuzzy growth in the petri dishes that appeared after several days.
What is mold?
This is a guess about an outcome or object based on your observations.
What is an inference?
This part of the atom is very dense, positively charged, and contains nearly all of the atom's mass.
What is the nucleus?
Oil does not have an affinity for water whereas salt does. Therefore, oils are ____ and salt is ____.
What is hydrophobic and hydrophilic?
Nucleic acids are not obtained from the foods we eat but are extremely important because of this function they perform.
What is store and transfer genetic information?
In the water lab, approximately half as many drops of soapy water fit on the head of the penny as did drops of plain water as a result of this.
What is surface tension?
This describes how close your measurements are to each other.
What is precision?
These are specific subatomic particles that are lost, gained, or shared in chemical bonds.
What are valence electrons?
Water's unique properties are mainly due to this characteristic which is the unequal distribution of charges.
What is polarity?
When it comes to proteins, "form dictates function" which means this.
What is the shape of the protein determines what it does in the body?
Surface tension is critical to sustaining life in a pond because it allows certain insects to do this.
What is walk on the water's surface?
This experiment variable is placed on the Y-axis of a graph.
What is the dependent variable?
Periods, or rows, on the periodic table share the same number of these.
What are energy levels?
These 5 properties of water make it unique.
What are adhesion, cohesion, high specific heat, less dense as a solid, and solvency?
Polymerization, or the making of polymers by linking monomers together, occurs by the removal of a water molecule. Breaking polymers into monomers occurs by the addition of a water molecule. These processes are respectively known as this.
What are dehydration synthesis and hydrolysis?
