Blog #4 Types of Selections

Directional variation is when a species have extreme variations in traits in an environment. An example of this are Greyhound Dogs, these dogs were breeded to have the greatest speed even running up to  40mph! Stabilizing selection favors the average traits in a population such as Siberian Huskies. All of the huskies have strong leg muscles so they could walk/run through dense snow easily. Disruptive selection favors the extreme traits in a species. An example of this could be birds with large beaks, by having these beaks they could survive longer than other bird with smaller ones.

Blog #3 Microevolution

Microevolution is a change in gene frequency in the (one) population. The ways that this may occur are mutation, artifical AND natural selection, gene flow, and genetic drift.

Blog #2 Fossils Hard to Interpret

There are many things that fossils could've been. They could've been plants, animals, and many more. There are not many facts that a fossil may give us. All we may 100% know is that something died and was buried at that spot. We may not know how the thing died or when it died. Unless the feature is easily seen like a large blow to the skull and is noticeable, we may not know how the thing died.

Blog #1 Evolution Theory

Evolution is considered as a theory because evolutionists have not been able to prove that it has taken place. Many people think that it is a law because earth's lifeforms has evolved over billions of years.  In science, a law is explanation of the natural world that is so firmly established that it has a very high chance of not changing.

Blog #14 (Favorite/Least Favorite Activity)

My favorite topic was the energy with chips experiment. The activity was pretty fun and interesting to burn them and see how the temperature changed.  The was kind of weird how some of the chips would catch on fire faster and last longer than the others. I thought that was pretty interesting to see and test out.

My least favorite topic was the karaoke project. I didn't really like finding a song to create our own lyrics to. It seemed to take a lot of work to do all that. The one thing that I would change about that would be that we didn't have to sing it out loud to the class but we could've put the background music and the lyrics on the screen and everybody could sing along while earning extra credit.

DNA has emerged as a powerful tool for investigating crimes and finding out the true suspect. It is possible to identify the suspect through a single strand of hair! You would be able to find out their gender, ethnic background, age, and much more. Genealogical DNA tests and DNA profiling are the two main tests for investigation. Genealogical DNA tests examine the nucleotides of a person and provide genealogical information about the person. DNA profiling are encrypted sets of numbers that make up a person's DNA makeup.

P1 looks all alike because they contain the dominate gene. Due to that their children will have the dominate trait instead of the recessive. This causes many of the offspring to be either heterozygous or homozygous with the dominate trait.
