Activity Instructions Analyze the data presented in the graph and table below. Then write a summary addressing the following:

1. The histogram below shows the total estimated new breast cancer cases diagnosed in 2003.

2. The results in this table below are from a 2007 study investigating BRCA mutations in women diagnosed with breast cancer. All of the women in the study had a family history of breast cancer.

BRCA Mutations in Women Diagnosed with Breast Cancer
*A mastectomy is the surgical removal of one or both breasts, either partially or fully. An oophorectomy is the surgical removal of an ovary or ovaries.

Things to address in your summary essay:
1. Describe how mutations lead to genetic variations.
2. Which appears to be more dangerous: the BRC1 or BRC2 mutation?
3. Analyze a woman’s risk of dying of cancer if she carries a mutated BRC1 gene.
4. How do heredity and inheritance relate to the data presented in these charts?
5. What data would you need to see in order to draw conclusions about the effectiveness of preventive surgeries?
6. What does the age at diagnosis tell you about the mutation?
7. Explain how breast-cancer genes are still present in the population, despite cancer-related surgeries and deaths.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
