The effect, which the sea cucumbers have on the amount of total organic carbon (TOC) contained in sediments in the experimental tanks and how it relates to nutrient cycling. Given: The TOC (percentage of sediment dry weight) for an experiment for weeks (1–8 weeks) was measured for control tanks and sea cucumber grazed tanks and plotted against as a graph. Introduction: Nutrient cycling refers to the cycling of nutrients through biogeochemical cycles. It involves both biological and chemical changes. There are many different types of nutrient cycles that operate in nature. Carbon is an organic compound which is present in living organisms. The death and decomposition of organic matter as well as processes such as respiration leads to release of carbon into the atmosphere. Huge amounts of carbon are stored in marine sediments.

Using Punnett Squares Punnett squares are one good way to predict the outcome of genetic crosses. Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. The number of possible alleles from each parent determines the number of rows and columns in the Punnett square. Independent Assortment KEY QUESTION How do alleles segregate when more than one gene is involved? Mendel wondered if the segregation of one pair of alleles affects another pair. For example, does the gene that determines the shape of a seed affect the gene for seed color? This type of experiment is known as a two-factor, or dihybrid, cross because it involves two different genes. Single-gene crosses are monohybrid crosses. Visual Reading Tool: Two-Factor Cross: F₂ The Punnett square shows the results of self-crossing the F, generation of a cross between round yellow peas and wrinkled green peas. 1. List the different genotypes in the F, generation. What is the…

CHAPTER 12 LESSON 2 Applying Mendel's Principles READING TOOL Connect to Visuals Before you read, preview Figure 12-7. Try to infer the purpose of this diagram. As you read, compare your inference to the text. After you read, revise your statement if needed or write a new one about the diagram's purpose. Take notes on the lines provided. Then view the Punnett square and answer the questions below regarding the genotypes and phenotypes. Inference: Revision: Parent 2 rryy Gametes F ry Parent 1 RRYY Gametes RY RrYy The F, generation are all RrYy. 1. What is the phenotype of parent 1?. 2. What is the genotype of parent 1? 3.
