Sure, I can help you with relearning Bio B Unit 8. Here are some key topics and concepts that you should review:
1. Genetics: The study of genes, heredity, and genetic variation.
2. Mendelian Genetics: The laws of inheritance formulated by Gregor Mendel, including the law of segregation, the law of independent assortment, and the law of dominance.
3. Meiosis: The process of cell division in which four daughter cells with half the number of chromosomes of the parent cell are produced. Meiosis is involved in the production of gametes (eggs and sperm).
4. Mitosis: The process of cell division in which two daughter cells with the same number of chromosomes as the parent cell are produced. Mitosis is involved in the growth and repair of cells.
5. DNA: The molecule that contains the genetic information of an organism. DNA is organized into chromosomes, which are located in the cell nucleus.
6. Protein Synthesis: The process by which genetic information carried by DNA is used to produce proteins. This process involves transcription, in which the DNA code is copied into mRNA, and translation, in which the mRNA code is translated into a specific sequence of amino acids.
7. Genetic Disorders: Abnormalities in the genetic material that can result in functional impairments or diseases.
8. Genetic Engineering: The manipulation of the genetic material of an organism to produce desired traits or characteristics.
I hope this helps! Let me know if you need more specific guidance on any of these topics.

Why does the population of mice look different between the first and last picture below?
Captionless Image
The hawk would randomly pick its prey
The tan mice were more visible and easier for the hawk to see.
The dark mice likely did not taste as good
There is no difference between the pictures.

There is no difference between the pictures.
The population of mice looks different between the first and last picture because the tan mice were more visible and easier for the hawk to see. This means that the tan mice were more likely to be preyed upon, leaving a higher proportion of dark mice in the population over time. This is an example of natural selection based on a selective pressure of predation.
