Question 1
White rabbit with black rabbit photo WP32787

In rabbits, black fur is dominant to white fur. As a rabbit breeder, you crossed a BB male with a Bb female, please complete the Punnett square for the possible genotypes of the offspring. Then complete, the percent chance for the phenotypes of the offspring.

***Please follow all Punnett square rules to complete this question.

a
linear growth within a population

a
A
 b

Question 6
A species of rabbit lives in a meadow where grass plants are readily available during summer months. The rabbits do not stray far from the meadow because the plants supply food and protection from predators. One summer, a fire destroys the plants in the meadow.

increase reproduction.
 b
decrease in size.
 c
increase and flourish.
 d
switch to a different type of food.

### Question 1 To complete the Punnett square for the cross of a homozygous dominant black rabbit (BB) with a heterozygous black rabbit (Bb), we will set up the square as follows: ``` | B | B | ------------- B | BB | BB | ------------- b | Bb | Bb | ``` **Offspring genotypes:** - BB - BB - Bb - Bb **Phenotype percentages:** - % Black (BB or Bb): 100% - % White (bb): 0% ### Blanks for Question 1 1. BB 2. BB 3. Bb 4. Bb 5. 100% 6. 0% 7. N/A 8. N/A 9. N/A 10. N/A --- ### Question 2 Which of the following refers to a population reaching a size that can no longer be supported by available resources in the surrounding environment? **c: carrying capacity** --- ### Question 3 Density-independent factors are limiting factors whose effects are **c: not influenced by population densities** --- ### Question 4 What does B represent on this growth curve? **b: a population's carrying capacity** --- ### Question 5 Which of the graphs below BEST resembles this deer population? (You would select the graph that shows a "S-curve" where the population grows logistically, reaching a plateau as it approaches carrying capacity) **(You would need to choose the correct graph label from the image provided)** --- ### Question 6 As a result of the absence of plants in the meadow, the rabbit population will probably? **b: decrease in size.** --- ### Question 7 In this food chain, the spiders are — **a: secondary consumers** --- ### Question 8 Which of the following is NOT true about matter in the biosphere? **d: The total amount of matter decreases over time.** --- ### Question 9 (For this question, there seems to be missing context regarding what trait or alleles are being referred to) - a: DD - b: female without dimples - c: Dd - d: male with dimples (You would select the relevant answer based on the context given, which is not provided here.) --- ### Question 10 Select ALL characteristics and information that CAN be obtained from a karyotype? - **a: location of centromeres** - **b: biological gender** - **c: number of sex chromosomes** - **e: number of chromosomes** - **f: number of autosomes** **Note:** A karyotype cannot provide information about specific single-gene inherited diseases, which is why option d is not included.
