Look up Gregor Mendel and his pea plant experiments Why does P1 look all alike and F1 looks very different?

The P1 looks the same because they are purebreds and are parents.  The F1 looks different because it has a mix of different genes from the other generations.

In the movie Gattaca parents were allowed to pick the traits of their babies, should we be able to do this? Why or why not?

No, because if parents were able to pick the trait for their child, then everyone will be the same. Most parents would pick only the perfect trait to have as their child. If the whole world is perfect, then no one would be special.

Step 1) Shred Cabbage - I use my food processor for speed and ease. If you shred by hand, make sure the shreds are no thicker than a nickel or dime!

Step 2) Mix, with wooden spoon or very clean hands, 5 pounds of shredded cabbage with 4 tablespoons of Kosher salt (pickling salt will do but changes the flavor a bit - do not use table salt) and toss and mix thoroughly until kosher salr dissolves! (You can make as much as you wish as long as you use the ratio of 5 lbs. cabbage to 4 Tbs. salt.)

NOTE: If you plan on refrigerating and not canning use 3 tbs of salt not 4!

Step 3) When juice starts to form on cabbage from tossing - Pack the cabbage firmly and evenly into a clean crock, glass or enamel container. Press firmly to encourage juice formation. Fill the utensil no closer than 5 inches from the top.

Step 4) Make sure juice covers the cabbage completely! (This does not always happen unless the cabbage is fresh from the garden) I prepare additional brine by putting 1 1/2 Tablespoons of kosher salt into 1 quart of boiling water. Dissolve salt and cool brine to room temperature before adding to the pot of cabbage.

Step 5) Once cabbage is immersed in brine water, place a large food grade, plastic bag filled with brine water and lay on top if cabbage... (I use 2 large bags, one inside the other   - sometimes a 2 gal freezer bag - with a couple of quarts of cooled brine water inside - this if the bag breaks it will not water down the cabbage into a tasteless mess)

The cabbage must be well sealed all around with the bag, so no air can get in and contaminate the sauerkraut with unwanted yeasts or molds!

Step 6) Now cover the container with plastic wrap, then a heavy towel or cloth and tie securely into place. Do not remove this until fermenting is complete!

Step 7) Put in an area where the temperature will not be above 75 degrees. Fermentation will begin within a day, depending upon the room temperature.

Step 8) If room temperature is 75 degrees allow 3 weeks for fermentation. If temperature is 70 degrees allow 4 weeks. If temperature is 65 degrees allow 5 weeks. If temperature is 60 degrees allow 6 weeks.

Step 9) Once fermented taste to see if your required tartness exists. Tartness will weaken as you process in canning so make sure it is a wee bit more tart than you like!

 

NOTE: The sauerkraut may not ferment and could spoil, If temperature is above 75 or 76 degrees!

!!!!! Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, and using an endogenous electron acceptor, which is usually an organic compound. In this recipe due to fermantaion the cabage is cooked over time, with any heat.

How far should the government go in isolating people with an infectios diseases? Should the army be involved?

The government should lock the infected people in a giant hospital room. They are needed to be isolated just in case someone breaks out and infect more people. A nurse or a doctor should check up on the infected people every hour. The army shouldn't be involved in this case. There is no point of shooting anyone because people shouldn't get their life taken away just for being infected. They should only be isolated from everyone else who isn't infected.

 Fermented milk are fermented with bacteria. The fermentation increases the shelf life of the product and adds the taste and improves the digestibility of the milk. There were evidence found that fermented milk has been in use since 10,000 B.C. 

Streptococci are round bacteria. Although streptococci are responsible for many disease, most types of streptococci are harmless. They remain in the throat and mouth. When they enter the bloodstream where they are killed quickly by the body defense systems.

Planet hunters led by astronomers discovered a newly found planet. This planet is an Earth-sized planet that has three times the mass of Earth. There is a possible chance that this planet has liquid water that could exist there. This planet orbits a nearby star at a distance that places it in the middle of the star's habitable zone. The Earth-sized planet has an orbitual period of 37 days. The mass shows astronomers that this is a rocky planet with a surface and has enough gravity to hold on to the atmosphere.

Are non carbon based life forms possible? Why or why not? Give at least two reasons to support your answer

Non carbon based life forms are not possible because complex molecules are made up of carbon which is bonded with other elements including oxygen, nitrogen, and hydrogen. Carbon is made up of four valence electrons it is able to bond with these elements which all living things need to survive. Everything living things eat has carbon in it. Without carbon, living things will not be able to survive.

Several years ago  NASA rocket failed because scientists were not using the same system of measurement for all the parts. Should the US switch to the metric system? Why or why not? Give at least two reasons to support your answer
The US should switch to the metric system because the metric system is able to help scientists measure rockets.  Using the metric system is faster than measuring in inches or feet. Scientists can check about how many meters a rocket goes in 1 second. The US should only use the metric system to measure every rocket.

My goals for this year are getting straight A's on every semester, get into the basketball team, and getting a girlfriend. I want to make my parents proud by getting 4.0 this whole year. I also want to get A's on every quiz and test in biology. Not only do I want to make my parents proud but I want to be proud of myself by making into the freshmen basketball team for Alhambra High School.
