Middle School Biology for RoRo

Horizontales
The process in which radioisotopes release particles and energy.
Positive ions formed by losing electrons.
Bonds formed between ions with opposite charges.
A homogeneous mixture of solvent and solute.
The most common steroid, mainly synthesized in the liver and is the precursor to many steroid hormones.
A state of relative balance between reactants and products is reached.
Negative ions formed by electron gain.
The smallest unit of matter that retains all of the chemical properties of an element.
The substances that go into a chemical reaction are called these.
Biological molecules made of carbon, hydrogen, and oxygen in a ratio of roughly one carbon atom to one water molecule.
A neutral, or uncharged molecule that has an asymmetric internal distribution of charge, leading to partially positive and partially negative regions.
A testable explanation.
Ions that are necessary for nerve impulse conduction, muscle contractions and water balance.
Glucose and galactose are these type of isomers of each other: their atoms are bonded together in the same order, but they have a different 3D organization of atoms around one of their asymmetric carbons.
The more electrons that are shared between two atoms, the stronger this type of bond between them will be.
Reactions that can go in both the forward and backward directions.
The attraction of molecules for other molecules of a different kind.
Verticales
The group that is not the experimental group but is the group that does not receive the treatment and provides a baseline that lets us see if the treatment has an effect.
The mass per unit volume of a substance.
Polymers are long chains made up of repeating molecular subunits, or building blocks, called these.
Because this atom can form covalent bonds to as many as four other atoms, it’s well suited to form the basic skeleton, or “backbone,” of a biological macromolecule.
This type of bond is of weak intermolecular interactions that do not involve covalent bonds or ions.
These type of atoms have unstable nuclei, and they will eventually release subatomic particles to become more stable, giving off energy in the process.
Lactose, maltose, and sucrose are examples of these type of polymers of two glucose monomers.
A type of solution that has a high concentration of hydrogen ions (H+), greater than that of pure water.
Saturated fatty acids have tails that are straight, so fat molecules with fully saturated tails can pack tightly against one another. This tight packing results in fats that are what state of matter (solid or liquid) at room temperature?
Anything that occupies space and has mass.
The only atom that has one proton and one electron, but no neutrons.
The substances produced at the end of a chemical reaction are known as these.
The attraction of molecules for other molecules of the same kind.
Forms of the same atom that differ only in their number of neutrons.
The factor that is different or varies between the control and experimental groups.
