To mix this drink you will need a chilled cocktail shaker, a chilled cocktail glass, a cocktail spoon, a cocktail strainer, a jigger, chilled gin, chilled vermouth, plenty of ice, and an olive.  Measure out 4 small jiggers of gin. Measure out 1 small jigger of vermouth. Place the ice in first and then add the vermouth. Swirl the vermouth around to coat the ice cubes and the shaker. Pour in the gin.  Leave the olive out, and add it once you have poured the drink into the serving glass. If you want your martini to be extra dry, pour out the excess vermouth using a strainer before adding the gin. Stir the drink for about 60 seconds so that the drink will be chilled sufficiently, diluted properly, and mixed thoroughly. Using a strainer to keep the ice in the shaker, pour the drink carefully into the serving glass. You can place the olive on a cocktail toothpick, or you can just drop it directly in the martini. Serve the drink immediately.

Q: Once you have analyzed all of the family members that you plan to include, make a list of their eye colors. This list will need to be analyzed either by hand or using computer software to determine possible eye colors for the baby. If you have no experience with inherited genes, you should use a computer program or consult someone that has knowledge of how genes are passed down. For example:  Father: blue eyes Mother: brown eyes Paternal Grandmother: brown eyes Paternal Grandfather: blue eyes Maternal Grandmother: brown eyes Maternal Grandfather: blue eyes Online calculators do most of the biology and math for you. Enter the eye color of each relative (e.g., parents, grandparents, aunts, uncles) in the indicated fields. When you are finished, the program will analyze the data and tell you the likelihood of each eye color. A Punnett square can be made for eye color by drawing a chart with 2 columns and 2 rows. On top of the columns, list the father’s alleles (genotype) for eye color. Along the left side of the rows, list the mother’s alleles for eye color. If you can determine the 2 genes that each parent has (this is easiest if both parents are homozygous), you can make a Punnett square. This square will tell you the possible gene combinations for your baby, which will indicate the possible eye colors. The Punnett square will also show the probability of each color. There should be 4 blank spaces under the father’s alleles and to the right of the mother’s alleles. In each space, write the father’s allele from the above it and the mother’s allele from the left of it. These 4 gene combinations are the possible combinations of your baby. The 4 boxes represent possible combinations of alleles. Each box represents a 25% chance that your baby will have that combination of alleles, and thus the eye color that it represents. If a certain combination does not appear in any box, there is no chance of having that combination. If a combination appears more than once, the chance of the baby carrying those alleles is greater. In the example above, it is clear that the father is homozygous (because blue eyes are recessive) and that the mother is heterozygous (because her father had blue eyes and could only have passed that gene). This allows you to make a Punnett square with 4 boxes. The likelihood of the baby having brown eyes will be 50% and the likelihood that it has blue eyes will be 50%.
A: List all known genes for eye color. Use an online calculator. Draw a Punnett square. Fill in the Punnett Square. Determine the probability of different eye colors.

Article: Load-bearing dry stack walls should be started at the corners. Begin constructing corners by laying 1 stone in the corner of the trench. Then lay 3 stones extending out in each direction. This forms the corner joint. If the wall is more than 1 stone thick, lay more stones parallel to the first ones. Act as if each section represents one stone. Construction bricks are designed to interlock at corners. The 4 stones you laid from each direction forms the first layer of cornerstones. For the second layer, overlap the first stone by laying another on top of it. Continue interlocking the stones as you build upward, alternating which side lays over the other.  The interlocking stone structure should look like a zipper going up. Stack 3 to 5 layers of stones at the corner before filling in the rest of the wall. Then if you need to go higher, stack more layers at the corners. After constructing the corners, extend outward from here and fill in the rest of the trench. Interlocking bricks have shapes cut into them that line up with the other bricks. Fit the bricks together as you lay them in place. Place the bricks in the trench all along the perimeter to form the first layer.  Make sure each rock you place is secure. Push it down to lock it in place snugly. Pound them down gently with a rubber mallet if you have to. Always stack a complete layer around the whole perimeter before starting another layer. When starting a new layer, each rock should overlap the joint between the rocks below it. This helps make your wall more stable. Continue this pattern as you stack more layers. If your bricks are smaller and you need to use more than one to cover the width of the trench, make sure the stones nearby touch each other. Otherwise, the wall won’t be able to support much weight. Part of the reason you need a stem wall is to keep ground moisture away from the structure you’re building. Stacking the wall at least 1.5 feet (0.46 m) above ground level helps keep your structure dry and avoids water damage. Do not build the stem wall higher than 8 feet (2.4 m). A wall higher than this requires extra reinforcement. Many localities even ban stem walls higher than 4 feet (1.2 m) for safety reasons.
Question: What is a summary of what this article is about?
Lay a cornerstone in each corner. Construct the corners by interlocking stones. Lay the stones down for the first layer of your wall. Stagger the rocks as you start new layers. Stack your wall at least 1.5 feet (0.46 m) above the ground level.
