Answer:
Evenly distributed
Question 3: Lab 26 Chromosome Study- What is a sex chromosome?
Answer:
One pair of chromosomes that determine the sex
Question 4: Lab 26 Chromosome Study- What are homologous pairs?
Answer:
The chromosomes exact copy or pair.
Question 5: Amnion Lab- What did the water represent?
Answer:
Amniotic Fluid Question 6: Lab 17 Mitosis Slides- What is the difference between plant and animal mitosis?
Answer:
Plant cell mitosis does not involve furrowing instead it involves the formation of a cell plate
Question 7: Respiration- How did sugar affect the rate of respiration?
Answer:
Adding sugar to it increases the rate of respiration because respiration is the process of breaking down sugar Question 8: Lab 17- What percentage of salt and water on the inside do Elodea cells normally contain?
Answer:
1% salt and 99% water on the inside Question 9: Respiration- Why does bromothymol blue change yellow when yeast is added?
Answer:
Because yeast was carrying on respiration
Question 10: What is a hypotonic solution?
Answer:
When the concentration of a solute molecules outside the cell is lower than the concentration in the cytosol
Question 11: Lab 26 Chromosome Study- What is a somatic cell?
Answer:
Any cell forming the body of an organism Question 12: Lab 17 Mitosis Slides- What mitotic structures can actually be seen on slides?
Answer:
All but centromere and centrioles
Question 13: Lab 17- What does salt water have a higher concentration of compared to fresh water or Elodea leaves?
Answer:
Salt
Question 14: Amnion Lab- What did the paper clip represent?
Answer:
The embryo Question 15: Lab 17- Describe the location of chloroplasts in a plasmolyzed cell (in salt water)
Answer:
Bunched together
Question 16: Lab 17- What direction should water move from?
Answer:
From high to low Question 17: Lab 26 Chromosome Study- What is the criteria for matching chromosome pairs?
Answer:
The position of the centromere, the banding patterns, and the size of the chromosome.
Question 18: DNA Model- What is base pairing?
Answer:
Cytosine pairs with guanine and adenine pairs with thymine in DNA
Question 19: What is a isotonic solution?
Answer:
When the concentration of solutes outside and inside the cell are equal. The cell doesn't change.

Answer:
The amniotic sac
Question 24: Lab 26 Chromosome Study- What is trisomy?
Answer:
When there are three instances of a particular chromosome instead of a normal two
Question 25: What is a hypertonic solution?
Answer:
When the concentration of a solute molecules outside the cell is higher than the concentration of the cytosol
