Biology Midterm Review

Biology Midterm Review, Mrs. Martinelli.

In case you didn't hear/lost the essay questions for her midterm, here they are:

1. Explain the differences between how Darwin and Lamarck would determine the trait from the article given.

2. Give your reaction to and define genetic engineering.

3. Explain the processes of photosynthesis & respiration. Include reactions, products, equations, and the connectedness of the two. Explain the BTB lab in explanation.

4. Explain the theme of surface area. Give 5 examples and what that increased area allows it to do.

5. Draw a DNA molecule. Label ALL of it's components & explain how it contrasts with RNA.

6. Draw a plant or animal cell. Draw 5 organelles and explain their function. Each organelle after 5 that you draw and explain is worth 1/2 a point.

Also, here are 8 surface areas.

Root Hairs - Plant
Alveoli - Lungs
Nephron - Kidney
Villi - Small Intestine
Thylakoids - Chloroplasts
Cristae - Mitochondria
Cerebrum - Brain
RBC - Body

Terms

undefined, object
copy deck
Respiration and photosynthesis are related because
Respiration used the products of Photosynthesis as reactants & vice versa
A theory is a
prediction
G1
Active Growth Period; Protein Synthesis; No Dividing; Nerve Cells and RBC stay here
Fermentation takes place when there is a lack of
Oxygen
Schwann discovered
Animal Cells
During genetic engineering, the gene is inserted into the
Bacterial plasmid
Examples of Genetic Engineering
HGH, Insulin
Two Types of fermentation
Lactic acid and Alcoholic
Decomposition
Breaking down reaction
Leaf Stomates open in
Light
What two things get passed down through reproduction
Genes and mutations
The higher the magnification of a microscope, the
Smaller the field of view is
S
DNA Synthesis of new set of genes; Errors = mutations (SOME harmful)
Organic compounds contain
C and H
Telophase
2 new nuclear envelopes form round the 2 groups of chromosomes at poles and the cell splits
Lipids are made up of
Fatty acids and glycerol
For an object to look normal under a microscope, it must be placed
Upside down and backwards
The age of Earth is
4,6 Billion
Dark Reactions
(Calvin Cycle) CO2 gets fixated into 2 molecules of PGA, then to PGAL with the NADPH + ATP form light
G2
Short growth with small amount of protein and RNA synthesis
Schleiden discovered
Plant Cells
Metaphase
Chromosomes line up in middle of cell
The age of the earliest fossils
3.5 Billion
Enzymes catalyze
Specific substrates
The cell membrane is made of
Two Phospholipid layers
Biogenesis
Living cells can come only from other living cells
Respiration Equation
C6H12O6 + 6O2 -> 6CO2 + 6H2O + 38ATP
Photosynthesis Equation
6CO2 + 6H2O -> C6H12O6 + 6O2
Passive transport
no energy needed
Scientific Method
Problem, Hypothesis, Experiment (Materials + Procedure), Results, Conclusion
Unicelled eukaryotes produced
New organisms
Proteins are made up of
Amino Acids
At the end of mitosis, the cell begins
G1 again
Autotrophs are either photosynthetic or
Chemosynthetic
DNA Phosphates
A+T, G+C
Leaf Stomates swell with
Water
Ionic bonds are
Stronger than hydrogen bonds, but weaker than covalent bonds
Genetic Engineering
Manipulating DNA in cells to improve health
Cell Cycle
DNA synthesis + cell reproduction
Darwin's theory was based on
Organisms changing over time, leading to variations
RNA Phosphates
A+U, G+C
Electrons can either be
shared or transferred
Hydrogen bonds are
Weak
Nucleic Acids contain
DNA and RNA
Respiration Reactants
C6H12O6 + 6O2
The whole point of Respiration is to make
38 ATP
Franklin and Wilkins discovered
DNA is the same language in all organisms
When dealing with a bioethical situation, three things you should are
Weigh factors, respect human life, and don't play games
Wilting is also known as
Plasmolysis
The age of our universe is
15Billion
Multicelled eukaryotes used the cell cycle for
Maintenance and repair of cell + growth
Heat doesn't recycle because of
Loss of heat
M
Mitosis stage with chromosome replication & production of 2 nuclei from 1 & cell division
Prophase
Chromosomes condense, nuclear envelope disappears, microtubules form spindle fibers which attach to centromeres of chromosomes
DNA contains
Deoxyribose Sugar
Covalent bonds are
Strong
Vircow believed in
Biogenesis
Respiration Products
6CO2 + 6H2O
Isotopes are different from regular molecule in that
They have different numbers of neutrons
Watson and Crick discovered
The structure of DNA double helix
Light Reactions
Chlorophyll in thylakoids absorb light, convert it to ATP; Splits H2O into H2 + O, and NADP carries the H2 to the Calvin cycle
The control is the
Standard for comparison
Prokaryotes produce new bacteria by
Binary Fission
Schwann & Schleiden developed the
Cell Theory
Hypertonic
too little water and can shrivel (crenation)
Photosynthesis Reactants
6CO2 + 6H20
The number of neutrons =
Mass # - Atomic #
Phospholipids are made of
Proteins
Atom
Smallest particle of element
The Five Stages of the Cell Cycle
Interphase, Prophase, Metaphase, Anaphase, Telophase
Ecosystem
Producer-Consumer-Decomposer
Lamarck's theory was based on
Acquired traits being inherited
Isotonic
equal amt. of solute on both sides
Low osmotic pressure
low solute = hypotonic
The three steps of cellular, aerobic respiration
Glycolysis, Krebs, ETC
Hypotonic
too much water and can lyse
ATP and NADP are
Energy storing compounds
Urinary System
Urea concentration is high in urine since kidneys keep the level of urea low in blood
High osmotic pressure
high solute = hypertonic
Binary Fission is simpler than the
Cell Cycle
Photosynthesis Products
C6H12O6 + 6O2
The number of protons in a molecule =
Electrons and Atomic #
How many ATP does fermentation make
2
RNA contains

Anaphase
Centromere divides and the 2 chromatids become separate chromosomes which move to opposite ends of the cell
Peptide bonds connect
