Life and Scientific Method
The cell
Life emerges at the level of?
How beneficial or harmful mutations are depends on the environment
Are mutations usually beneficial or usually harmful?
The smallest individual units that have properties of an element
What are atoms?
They can gain a third hydrogen and you get a positive charge.
Why is an amino group considered basic?
Hydrophilic
Protein surface is what type of amino acid?
Must be testable
What is the main requirement for a scientific hypothesis?
The 5 mass extinctions that have happened
What can we learn about the history of life on Earth through the geologic record?
Transfer electrons
What do Ionic Bonds do?
It reduces the PH
Does the absorption of carbon dioxide by the oceans lower or raise the pH?
Hydrophobic
Protein interior is what type of amino acid?
Has an effect on the dependent variable
The independent variable
DNA passed from one bacterium to another, also by a virus injecting DNA from another bacterium into it's genome
How are bacterial resistance genes spread from bacterium to bacterium, and how are are they spread throughout the environment?
Share electrons
What do Covalent Bonds do?
Hydrophilic functional groups
Molecules with which functional groups will be soluble (dissolved in) in water?
Tautomeric shifts cause mutations in DNA by typical and atypical base pairings
How do tautomeric shifts cause mutations in DNA?
Domain Bacteria, Domain Archaea and Domain Eukarya
What are the three domains of life?
Bacteria becomes resistant to antibiotics by genetic mutation and DNA exchanges
How does bacteria become resistant to antibiotics?
Oxygen, Carbon, Hydrogen and Nitrogen
Which four elements are most important and prevalent to life on Earth?
Reducing available carbon ions available as well as drops in metabolic rates and immune responses.
How does ocean acidification affect marine life?
They speed up chemical reactions by lowering activation energy and making their transition state more stable
What do enzymes do and how do enzymes do their jobs?
The biosphere
What is an example of an emergent property?
our crops, livestocks and pets having little resemblance to their wild ancestors. As well as the unintentional evolution such as habitat loss and climate change that is causing a loss in species
How does artificial selection lead to changes in populations over time?
Protons: determine element
neutrons: determine isotope
electrons: form negative cloud and determine chemical behavior
What do the three subatomic particles: protons, neutrons and electrons do?
It will increase the acidity of the water
How might humans be affected?
Temperature, changes to PH and changes to salt.
What are the things that can affect enzyme activity?
