Ecology
A population is a group of organisms of the same ___________.
What is species?
Aerobic respiration is ___________________________________________________.
What is the process of using oxygen to break down glucose to produce energy in the form of ATP?
DNa replication is important because _________________
must replicate DNA to make new cells
During meiosis I _____________ separate while during meiosis II ________________ separate.
What is homologous chromosomes? What is sister chromatids?
The mitochondria is...
What is the powerhouse of the cell? It creates energy for the cell from carbohydrates.
What is true?
Aerobic and anaerobic respiration are different because ____________________________________________________.
Aerobic respiration requires the presence of oxygen while anaerobic respiration occurs when oxygen is not available. Aerobic respiration has 3 steps while anaerobic respiration only has 2.
When mistakes are made in DNA replication, you can have ______. Types of these are:
What is mutations? What is frameshift, inversion and deletion
Name 3 differences between mitosis and meiosis
1) Mitosis produces identical daughter cells while meiosis produces genetically different daughter cells.
2) Mitosis produces 2 daughter c ells while meiosis produces 4
3) Mitosis onnly has 1 "Stage" while meiosis has 2
The cell membrane is important because
What is it envelops the cell and protects the cell's internal environment? It is "selective" meaning only certain materials can come into the cell.
A food web contains ___________ pathway (s) while a food chain contains __________ pathway (s)
What is multiple, what is one?
What are the products of fermentation?
Fermentation regenerates the reactants for glycolysis. Pyruvate is converted into ethanol or lactic acid and regenerates intermediates for glycolysis.
Transcription occurs in the ___________. Trnaslation occurs in the ________. Replication occurs in the ______________.
What is nucleus? What is cytoplasm? What is nucleus?
Name an example of incomplete dominance and codominance:
Answers will vary
Explain the functions of the ER, golgi apparatus, lysosome and ribosomes:
What is the ER transports things, the golgi apparatus packages and ships things, the lysosome destroys waste and the ribosomes make proteins?
The carrying capacity is the maximum number of organisms that can survive in a population. This is caused by limited __________ being available. Examples of these are ________________ and _________.
What is resources?
What is amount of food and space available?
Catabolism and anabolism are ____________________________________.
What are types of metabolism? Anabolism is the synthesis of complex molecules while catabolism is the breakdown of complex molecules.
A tRNA carries a __________ and a _____________ which matches the __________ of the mRNA.
What is amino acid, what is anticodon, what is codon?
Explain the difference between phenotype and genotype. How can two organisms have different genotypes but the same phenotype
What is phenotype is appearance and genotype is genetic sequence. Organism could be heterozygous or homozygous dominant
DNa is found in the __________
What is nucleus?
A population of foxes show exponential growth until all of their prey (Rabbits) go extinct. Because of the loss of food, they now have a carrying capacity of 400 foxes. If rmax is .2 foxes per year, calculate the growth of a population of 100 foxes now that they have limited resources. How would it compare if the loss of rabbits never occurred and they had unlimited food supply?
What is 20? What is 15?
Explain in detail the 3 steps of glycolysis and what happens in each.
1) Glycolysis- glucose is broken down into pyruvate. ATP is produced.
2) Krebs cycle- pyruvate is converted into CO2 and FADH2 and NADH are produced
3) Oxidative phosphorylation- NADH and FADH2 are used to generate ATP
Explain transcription and translation step by step:
Transcription is the process of making mRNA from DNA. RNA polymerase adds RNA bases complimentary to the DNA. Translation is the process of making proteins; this happens in the cytoplasm. mRNA brings the codons to the ribosome where tRNa brings matching anticodons and corresponding amino acids.
Explain the difference between RNA and DNA
RNA is single stranded and DNA is double stranded. DNA stays in the nucleus while RNA is used to make protein in the cytoplasm
The difference between active and passive transport is __________________________________________________________.
Passive transport does not require energy- osmosis, diffusion are passive transport. Active transport requires ATP.
