Presentation Transcript
Name the three types of chromosomes
Sex Chromosomes
Autosomal Chromosomes
Homologous Chromosomes
Chromosomes for 100Back
Chromosomes for 200
- How many chromosomes are in the body cells of a dog that has a haploid number of 39?
- 78 chromosomes
Back
Homologous chromosomes contain many genes that code for what type of traits?
Same Traits
Chromosomes for 300Back
DNA is compacted by wrapping tightly around proteins.Chromosomes for 400
- In one cell DNA is about 2.5m in length. How can the DNA fit inside a cell that can only be seen with a microscope?
Back
Why is DNA only seen during the stages mitosis and not during interphase?
DNA is in a uncondensed form (chromatin) during interphase and a condensed form during mitosis.
Chromosomes for 500Back
Identify and describe the stage depicted below:
Centromeres double
Spindle Fibers shorten
chromosomes move to opposite sides of the cell
Mitosis for 200Back
These “cables” extend from the poles during metaphase. What are these cables called?
Spindle Fibers
Mitosis for 300Back
What is the end product of mitosis? (be specific)
2 diploid daughter cells that are identical to the parent cell
Mitosis for 400Back
During cytokinesis what forms in a plant cell and an animal cell?
Plant Cell – Cell Plate
Animal Cell - Furrow
Mitosis for 500Back
In a human cell how many chromosomes are located in the nucleus at the beginning of meiosis? At the end of meiosis?
Beginning – 46
End - 23
Meiosis 100Back
Name the processes of which sperm and eggs are produced in organisms.
Spermatogenesis (male)
Oogenesis (female)
Meiosis for 300Back
Meiosis for 400
- What are three ways that cell division lends to genetic variation in a population?
- Random fertilization
- Independent assortment of homologous chromosomes
- Crossing over
Back
What stage in meiosis do homologous chromosomes line up together?
Why must they line up together?
Metaphase I
The line up together so the division will produce haploid cells.
Meiosis for 500Back
What is the order of stages for aerobic respiration?
Glycolysis
Krebs Cycle
Electron Transport Chain
Cellular Respiration for 200Back
During the electron transport chain, electrons lose energy creating ______ to create an electrical gradient that produces ATP.
Protons
Cellular Respiration for 300Back
When are muscles are fatigued they tend to become cramped. Describe what is happening in terms of cellular respiration.
The muscle cells are switching to anaerobic respiration due to the lack of oxygen. The muscles are going through fermentation.
Cellular Respiration for 400Back
How much ATP is created by the breakdown of one glucose molecule in glycolysis? And how much is made during the entire aerobic respiration?
2 ATP
38 ATP
Cellular Respiration for 500Back
What does it mean when the cell membrane if referred to as selectively permeable?
only certain particles can pass through
Cell Transportation for 100Back
Some animal cells protect themselves from absorbing too much water by “pumping” excess water out. They use a __________ to do this.
Contractile Vacuole
Cell Transportation for 300Back
When the concentration of solutes inside a the cell is equal to the concentration of solutes outside the cell, the solution is said to be …
Isotonic
Cell Transportation for 400Back
