Steps of the Scientific Method

1. Observation


2. Hypothesis


3. Experiment


4. Data


5. Conclusion


6. Scientist report their findings in journals

How do enzymes affect biological reactions?

Enzymes lower the activation energy, thus more reactants can react and the the rate is increased

What properties (more than 1) of water are responsible for capillary action?

Cohesion, Adhesion, and Surface Tension

Molecules that are too large to pass through the cell membrane use this type of active transport

Enodcoytosis

Organelle responsible for converting chemical energy stored in food is?

Mitochondria

In which cells does cellular respiration. (Specifically Glycolysis)

- Cytoplasm


1. Glycolysis 2. Kerbs Cycle 3.Electron Cycle

What is the chemical equation for cellular respiration?

C6H12O6 + 6O2 + light energy = C6H12O6 + 6O2

Why do chromosomes condense during mitosis?

So that can be separated with relative ease, into equivalent halves


What occurs during translation of proteins?

In translation, messenger RNA(mRNA) - produced by translation from DNA - is decided by a ribosome to produce a specific amino acid chain, or polypeptide

Describe the structure of DNA. How is it different from RNA?

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. The 4 types of nitrogen bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).



-RNA is single stranded/ DNA is double stranded


-RNA has the pentode sugar ribose/DNA has deoxyribose


-RNA has the pyrimidine base uracil

Know the difference between homozygous recessive, homozygous Dominant, and Heterozygous.

-Homozygous is the same. Heterozygous is different.



-If something is homozygous it will have the same letters and if its heterozygous it will have a capital and lower case letter.

Mendel's ratio for the F2 generation was...?

3:1

Order of events for the origin of life? (Chp 14)

a. Formation of DNA based on generic systems



b. Synthesis of organic polymers



c. Formation of protobionts



d. Synthesis of organic monomers

Why were cyanbacteria important in the early life on earth?


What did they provide to the atmosphere?

- Cyanobacteria created oxygen, they provided the atmosphere with oxygen

What is the difference between a hominoid and hominid?

- hominoids are primate groups that include common ancestor of humans and apes

Give an example of an analogous structure

- Shark fins v Dolphin fins


- Moth wings v Bird wings


- Octopus eye v. Human eye

Define the endosymbiosis theory?

It's a theory where the mitochondria and chloroplasts of the cell are believed to have evolved from bacteria.

Know how to classify taxa from broadest to most specific. (DKPCOFGS)

1. Domain


2. Kingdom


3. Phylum


4. Class


5. Order


6. Family


7. Genus


8. Species

Which 2 kingdoms contain Orangism's w. Cell walls made of cellulose?

Kingdom Plantae and Fungi

Why are virus considered non living?

Because they don't have cells

Describe the limitations of the biological species concept?

Since it's dependent on dependent on sexual reproduction, the species concept may be hard to apply organisms that don't reproduce sexually

What are the 3 biochemical characters used by scientists to identify evolutionary relationships?

Fossil evidence, Embryology, and Anatomy

Define nitrogen fixation

Chemical processes by which atmospheric nitrogen is assimilated into organic compounds

What does it mean when a lake is eutrophic?

It has eater that's rich in mineral and organic nutrients that promote plant life

What's the difference between primary and secondary succession?

- Primary succession is the colonization of living organisms into an area that want previously colonized by any living things



-Secondary Succession is the regeneration of the living community after a major disturbance

What's the difference between limiting factor and range of tolerance?

- limiting factors are things that prevent a population from growing any longer



-cannot survive if there is too much or too little of the factor

Describe transpiration in plants

The loss of water from a plant by evaporation is known as transpiration. Most of the water is list throught the surface openings, or stomata, on the leaves.

Describe what the difference between density dependent and density independent factors is.


Density independent is a factor that affects a population based on it's population, including amount of resources, disease, etc. -



Density Independent factor is a factor that affects a population in a manner that doesn't vary according to the density of its population


etc.

Give an example of an R-selected species

Mice, Rabbits, Mosquitoes, Fleas, Weeds, etc

Know how to read an age structure

If the pyramid is top heavy there'll be a decrease of population. Bottom heavy there should be an increase in population in the coming years.

Give examples of renewable and non renewable resources

Renew: Water, O2, Timber, Fruit and Vegetables, Meat from animals



Non: fossil fuels
