A good hypothesis is ____
What is falsifiable and testable ?
100
The amount of _________ in an atom of a specific element will always stay the same.
What are protons?
100
This is an example of an __________ compound.
What is organic?
100
a bimolecular layer of lipids and proteins
what is plasma membrane?
100
What reaction is this ?
What is dehydration synthesis?
200
The emergent property at this level, in the organization of life, is a collection of two or more types of tissues.
What is the organ?
200
Define an isotope.
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons.
200
This macromolecule has a variety of functions including: structural, enzyme, transport, etc.
What is protein?
200
What type of reaction is taking place?
What is Dehydration synthesis
200
What are H-bonds
300
The genetic information in a bacterial cell is ___________.
What is free floating?
300
Fluorine will bind with__________in order to become stable.
What is Lithium?
300
What does the structure of a polypeptide monomer include?
the structure of an amino acid has a variable R group, an amino group(NH3+), a carboxyl group(COO-), and a Hydrogen
300
The plasma membrane plays a dynamic role in cellular activity by...
What is regulating the movement of material in and out of the cell?
300
In Chapter 2, what is the primary difference between ionic and covalent bonds?
The primary difference is that ionic bonds involve the transfer of electrons, resulting in the formation of ions, while covalent bonds involve the sharing of electrons between atoms.
400
Properties of life include
1. Order
2. Reproduction
3.________
4. Energy processing
5. ________
6. Response to the environment
7. ________
Growth and development, Regulation, Evolutionary adaptation.
400
Polar Covalent bonds cause partial charges to occur because...
one of the atoms in the bond is more electronegative/electron greedy and has a stronger pull on their "shared electrons"
400
What are the primary differences between DNA and RNA?
DNA: double stranded, thymine pairs with adenine, stays inside the nucleus
RNA: single stranded, uracil pairs with adenine, mainly active outside the nucleus
400
How does structure determine function when it comes to the endoplasmic reticulum ?
The ER is divided into the rough ER and the smooth ER. The rough ER has ribosomes that carry out protein synthesis. The smooth ER focuses on lipid synthesis and detoxification.
400
How does the concentration of hydrogen ions (H+) change when moving down the pH scale, as discussed in Chapter 2?
When moving down the pH scale (towards lower pH values), the concentration of hydrogen ions (H+) increases by a factor of 10, indicating increased acidity.
500
How does a Eukaryotic cell having a variety of membrane bound organelles affect its functioning
Each organelle can be specialized for a specific task, allowing the cell to seamlessly carry out a variety of different functions simultaneously. Structure determines Function!
500
The chemical bonds ranked from weakest to strongest are as follows:
Hydrogen bonds<Ionic bonds<Covalent bonds
500
A monomer of nucleic acid is called a nucleotide but a nucleotide also contains what macromolecule as part of its structure?
what is a carbohydrate? (pentose sugar)
500
The cytoskeleton helps organize the cell's structure and activities via these 3 different types of protein rods
What are microtubules, microfilaments, and intermediate filaments?
500
These are all examples of what level of protein structure?
What is Quaternary structure?
