Basics
This is the title given to something that is supported by an overwhelming amount of evidence
Theory
An electron in an atom's outermost electron shell is called this
Valence electron
This is an example of an acidic value
Under 7
Which type(s) of cell(s) has/have a chloroplast, a mitochondrion, a cell membrane, and a cell wall?
Plant
This organelle in plants stores water
Vacuole
White-tailed deer, gray squirrels, and silver maple trees altogether describe this.
Community
An atom with the same number of protons but a different number of neutrons is known as this.
For example, Carbon-12 vs. Carbon-14
Isotope
H+
Which type of cell has a mitochondrion?
Any eukaryotic cell
Plasmodesmata
All of the white-tailed deer in Woodbury represent this
Population
These are the 4 main elements of life
Carbon, phosphorus, nitrogen, hydrogen
Which organelle is responsible for the synthesis of lipids?
Smooth endoplasmic reticulum
This organelle is responsible for the production of proteins
Ribosome
The variable that you measure against something already set. For example, if you measure the number of bubbles produced by a plant submerged underwater during photosynthesis, the number of bubbles produced would be this variable.
Dependent
When electrons are unequally distributed around an atom, the partially negative side can temporarily attract a partially positive side of another atom. Which type of molecular interaction is this?
Van der Waals
When water sticks to other what molecules, what is this known as? Why does it happen?
Cohesion- the polar covalent bonds in each water molecule leads to a partially negative area and a partially positive area on each water molecule, with each of those being able to hydrogen bond with adjacent water molecules.
Which organelle deals with the modificiation, packaging and transport of proteins?
Golgi Body/Apparatus
Which type of cell lacks membrane-bound organelles, but still has a cell wall?
A prokaryote
You want to study the effects of ibuprofen on hormone production in fish. You take three aquariums, and expose a population of zebrafish to three different levels of ibuprofen- 0 mg/L, 2 mg/L, and 5 mg/L. What is the negative control? What could be a controlled variable?
Negative control- 0 mg/L
Controlled variable- water depth, sunlight amount, food type, age of fish, proportion of each sex, etc.
An atom with the same electronegativity as another atom will result in which type of bond if a valence electron is shared between the 2 atoms?
Nonpolar covalent bond
Which area on a water molecule is partially positive? Why?
Hydrogen, oxygen is more electronegative and pulls the electron that is shared between it and a hydrogen closer to itself. An electron is negatively charged and thus by pulling an electron closer, it becomes slightly more negative.
Three model cells
1:10 surface area to volume ratio
10:1 surface area to volume ratio
100:1 surface area to volume ratio
Which has the best ability to do cell processes?
100:1 (more surface area compared to volume)
The endosymbiont theory describes the origination of mitochondria and chloroplasts. They were once free-living prokaryotes engulfed by ancestral eukaryotes. They were not digested, but rather formed a symbiotic relationship.
