This is a method whereby conclusions follow from general principles
Deductive Reasoning
A method of arriving at general principles from specific facts
Inductive reasoning
What is the biological Classification in order?
Domain Kingdom Phylum Class Order Family Genus Species
What is the backbone of RNA and DNA that adjoins the bases together
Phosphate groups
This is the base that is the molecule that is found in DNA and RNA that encodes genetic information
Nitrogenous bases
What base does uracil take place of in RNA to DNA?
Thymine
Cells copy DNA into RNA by using the process called _________
Transcription
The process of protein production from messenger RNA is called
Translation
What is the final outcome of Mitosis? (exact copy)
Two diploid cells
What is the final outcome of Meiosis ? (split copy)
Four Haploid cells
At what stage of Meiosis does the spindle fibers form and the centrioles move to opposite sides of the cell?
Prophase
What phase of Meiosis do the chromosomes align midway along the spindle fibers?
Metaphase
What stage of Meiosis do the chromosomes begin to separate form their daughters and cytokinesis begins
Anaphase
What stage of Meiosis does the identical sets of chromosomes are at opposite sides of the cell, Spindle fibers disappear and nuclear membranes reappear and cytokinesis is complete
Telophase
This is a phase of meiosis where homologous chromosomes condense and link in the process forming tetrads, this allows crossing over to occur
Prophase I
This is a phase of meiosis where homologous chromosomes move to the metaphase plate
Metaphase I
This is a phase of meiosis where homologous chromosomes separate but sister chromatids stay together
Anaphase I
This is a phase of meiosis where cytokinesis has occurred and two haploid daughter cells are the result
Telophase I
This is a brief stage of meiosis in which spindle fibers begin to reappear and the centriole move to opposite poles
Prophase II
This is a phase of meiosis where sister chromatids align a new metaphase plate
Metaphase II
This is a phase of meiosis that is when sister chromatids separate again
Anaphase II
This is a stage of meiosis where four haploid cells result after cytokinesis
Telophase II
What type of organisms can not produce their own food?
Heterotrophs
What does Kinetic Energy equal?
1/2 the Mass times the velocity squared
1/2MV^2
What is of energy of motion considered?
KE
What is the stored energy known as?
PE
What is the PE calculated as?
PE=mass times standard of gravity times height
In photosynthesis, light strikes which molecule and releases high energy electrons and protons leading to chemiosmotic phosphorylation?
Water
Water _____ specific heat and ______ heat of vaporization means it takes a great deal of energy to change its temperature
High
High
When conveying a double bond of hydrocarbon, __ is always twice as much as ____
Carbon
Hydrogen
Protons should have which of the following characteristics when compared to the charge and mass of an electron?
Opposite charge, larger mass
When taking about a substance with high density, it means that the substance is _____ and _____ moving
Heavy
Slow
When a substance has a low density, it means it is _____ and _____ moving
Light
Fast
In autotrophs there are ______ and in heterotrophs there are ______
Chloroplasts
Mitochondria
This bond is known for sharing electrons
Covalent
This bond is viewed as the donation of electrons and accepted to keep structure
Ionic
Mutations in which cells can be passed on to offspring?
Germ Cells
A difference of two units on the pH scale represents a concentration of ___.
100
_____ + ______ equals the mass number
Protons and Neutrons
What is the equation to calculate heat removal?
H=-M times L
What would give off more energy? The sun or a star with the same energy farther away?
The sun, closer
