Constructing and Analyzing a Topographic Map In this task, you will create a topographic map based on a clay model. For the model and the topographic map, each contour line will represent an elevation change of 1 inch.

Estimated time to complete: 1 hour

You will need these materials:

lump of modeling clay (approximately 5 to 6 inches in diameter)
string (fishing line or dental floss works best)
ruler
pencil
8.5 x 11-inch piece of paper
After gathering your materials, follow these steps to create your mountain and topographic map.

Part A
Question
Reassemble your mountain by stacking the four pieces in the correct order. In the answer space, sketch a picture of your mountain and its corresponding topographic map. The mountain sketch should be a side view and should include the horizontal dashed lines indicating each section of the mountain that you traced onto your topographic map.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses.cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown.cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan.cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan.select the correct statements regarding the mode of inheritance of the coat color genes.a) both genes are x-linked.b) both genes are autosomal.c) one of the genes modifies the expression of the other gene.d) each gene has an additive effect on the intensity of coat color.e) each gene independently specifies three colors.f) one of the genes is autosomal, and the other is x-linked.

The circles, or orbits, for electrons are called energy levels. each level can hold only a certain number of electrons. add electrons to each level until you can't add any more. how many electrons can each level hold?
