Ap Biology Dirty Dozen Labs Review Packet Answers
The AP college board lists 13 labs for its recommended curriculum, summarized in the publication, AP Biological science Investigative Labs. However, teachers are not express to only using their versions of the lab. AP biology teachers submit a curriculum for review and blessing and must include laboratory exercises that align with their core ideas. Some of the recommended labs may be too expensive or also time consuming for your class. Listed below are some alternatives that may be adequate as role of your overall biology curriculum.
(AP Biological science) Possible Alternatives Notes
Evolution
Evolution drives the diversity and unity of life. Supported by evidence from many scientific disciplines, Darwin's theory of development states that heritable variations occur in individuals in a population; because of competition for resources, individuals with more favorable phenotypes are more than likely to survive and reproduce, thus passing traits to offspring.
Investigaton one:

Investigation 6: Cellular Respiration
What factors impact the rate of cellular respiration in multicellular organisms?
Virtual Lab: Cellular Respiration - a step-through activeness that mirrors the process of the investigation
Cellular Respiration - modified AP lab, uses respirometers to measure oxygen consumption
This lab requires equipment that may be hard to obtain or create. You tin society respirometer and lab kits from CarolinaGenetics and Data Transfer
Genetic information provides for continuity of life, and, in most cases, this data is passed from parent to offspring via Deoxyribonucleic acid. In eukaryotic organisms, heritable information is packed into chromosomes that are passed to daughter cells by mitosis, a controlled machinery that ensures that each girl cell receives an identical and consummate complement of chromosomes.
Investigation seven:
Prison cell Division: Mitosis and Meiosis
How do eukaryotic cells divide to produce genetically identical cells or to produce gametes with half the normal Deoxyribonucleic acid?
Role 1) Modeling Mitosis
Office 2) Effects of Environment on Mitosis
Part iii) Loss of Cell Cycle Control in Cancer
Part 4) Modeling Meiosis
Part five) Meiosis and Crossing Over
Mitosis Net Lesson-
Meiosis Internet Lesson - employ various sites to detect models of mitosis and meiosis
Mitosis in an Onion Root - view slides and count the number of cells visible in each stage
The Instance of the Dividing Prison cell - instance study where students learn stages of mitosis and meiosis, prokaryote versus eukaryote
Modeling Chromosomal Inheritance - using chaplet and piping cleaners to show how genes are passed from parents to offspring
Linkage Group Simulation - pipecleaners are used to model crossing over
Investigation: Mitosis - look at slides and real data from a cancer report to explore the role of P53 in the cell bike
Many of the activities listed in the investigation tin be performed as classroom discussions, lectures, and animations.
