What are three ways that organisms are classified?
Types of cells, Domain, Taxonomy

What are chromosomes? How many are humans suppose to have?
Chromosomes are arranged packages of DNA Humans have 46 chromosomes. 23 pairs. 23 from each parent.

Who was known as "The father of Evolution"
Charles Darwin was known as the father of evolution

What is an alveoli?
- single celled air sacs where gas exchange occurs
100
What do plants contain in cell walls?
Cellulose

What is taxonomy? what are the 2 types of cells that go along with it?
Taonomy is the grouping of organisms by similarities, The science of naming\ assigning them to groups. Cells. - Prokaryotes - Eukaryotes
200
What is Gametogenesis? what is it called when it occurs in males? females?
Gametogenesis is the production of gametes (Sex Cells) through the process of meiosis. - In males it is called Spermatogenesis -In females it is called Ogenesis

thinking of the Hardy Weinburg principal, What are the 5 agents of evolutionary change
1. Mutation 2. Gene Flow 3. Non- Random Mating 4. Genetic Drift 5. Selection

What is the organ that is surrounded by smooth muscles that undergo wavelike contractions to move air from the mouth into the lungs?
- Esophagus
200
What is the function of the root system?
- to absorb water and nutrients from the soil to help the plant grow.
300
What are the 2 main groupings of animals in Kingdom Animalia? what percent of species fall under each of the 2?
Invertebrates- 95% of animal species Vertebrates- 5% of animal species.
300
What are the four errors that can occur in chromosome structure called?
Addition Deletion Inversion Translocation
300
What is the difference between Homologous structures, Analogous structures and Vistigial Structures?
Homologous- structures that have the same bone\ muscle present but have been modified to do a specific job. Anologous- Structures that have the same specific job to do but dont have any similarilty in bone\muscle structure Vistigial Structures- Remants of past structures that have no longer use.
300
For gas exchange between the atmosphere and respriatory system surface to happen what must occur?
- moist respiratory membrane -the distance of diffusion is small -the surface are for diffusion is large
300
What are the 6 challenges that plants had to overcome to move from aquatic to a terrestrial existence?
- Getting out of the water - Preventing water loss -Staying upright -Surviving extreme temperatures\Moistures -Transport System -Reproduction
400
What are ways to classify a species?
Morphological- comparing measurments. Biological- Ability to breed, Reproduce, Offspring Phylogenetic- Focus on evolutionary relations.

What are the process steps in Meiosis. Starting with Early Prophase 1
Early Prophase 1 Late Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Interkinesis Prophase 2 Metaphase 2 Anaphase 2 Telophase 2

What are darwin's basic points?
1- organism's differ: variation is inherited 2- organism's produce more offspring than survive 3- organism's compete for resources 4- organism's with advantages survive to pass children 5- living species and descended with modifications
400
What is the relationship between blood pH and the amount of carbon dioxide in the blood?
When pH is low the more H+ is has therefore meaning more carbon dioxide since H+ is produced when carbon dioxide mixes with H2O in plasma.
400
How do plants reproduce? what are some benifits of producing this way?
Plants reproduce asexually. Benifits: - If a plant reproduces sucessfully then all offspring will have the same trait. - they do not need reproductive structure -only one plant needed -Higher survival rate

What are the six kingdoms called? Why arent viruses grouped into any of them?
Kingdoms - Achaebacteria -Eubacteria -Protista -Fungi -Plantae -Animalia Viruses are not grouped under any of these kingdoms because they are not capable of independent metabolic activity.
500
How is a mothers age related to the probability of non-disjunction of chromosomes in her egg cells? Why might non-disjunction be less likely in males?
Since all eggs are made up before birth and held at pre-meiosis throughout life, and only 1 develops a month therefore likely nono-disjunction can happen as a women gets older due to her egg quality. It is less likely for men because they constantly produce sperm
500
Why is the statement " Mutations alone are not likely to cause evolution" is true
- the four conditons are large population, lack of gene flow, lack of mutation, no natural selection. - in the wild these may or may not occur - Most of the 4 conditions occur in many populations. -Many organisms are adapted to living in particular environmental environments.

What would happen to the digestion of carbohydrates, proteins and fats when the pancreas is dysfunctional
- Wouldnt be able to complete the digestion of these nutrients since most enzymes come from the pancreas . would result in death.

what are the 3 types of tissue in a plant and what purpose do they have?
1. Dermal Tissue System- this is the outter most layer on plants which protects against excessive water and infections. 2. Ground tissue System- parenchyma, collenchyma and sclerenchyma. Parenchyma- this is involved with photsynthesis and the storage of nutrients,carbohydrates and water. Collenchyma- Helps strengthen the plant\specialized for supporting the plants primary growth regions Sclerenchyma- Cells that have secondary cell walls, this provides added strength. 3. Vascular Tissue- xylem&phloem. Xylem - is used for conducting water and minerals. Phloem- transports sugars and other solutes
