Final blog
Reflect on your semester and year in biology What were your successes? What were your failures?
What did you learn that you will never forget?
My successes in this year was my notebook. My notebook was really good throughout the whole year and i always turned it in on time. My failures was finals because i bombed it. I started to study too late and messed up my grades. I still had an A though. The things i learned that i will never forget is the dissection of everything we did.

Blog 15 .
Blog 14 Write a letter to Senator Feinstein describing what alternative energy source you think we should be pursuing. Give at least three reasons why.
Dear Senator Feinstein,
The alternative energy source we should be pursuing is the electricity lines. Its easiest to do do that because you can get electricity right away. The 3 reasons why that is best is since the wires give electricity manually. The second is since its the easiest way. The third is since they are all installed in our homes already.

Blog 14 Which specimen that we have dissected so far seems most like humans? Why?
The most specimen that seems like humans are crayfish because it has parts in there seems like human particles. It has 2 hands an abdomen and brains. It has a shell to cover it like ourselves the skin. The crayfish also has legs like us. The crayfish seems to look like us.

Blog 13 What was most interesting about this week's dissections?
The most interesting on this weeks dissection was the worm. I never knew there was so much in a worm and that was the biggest worm I've ever seen in my life. I saw all the insides of the worm and i was surprised it had so much parts in it. Another interesting thing about this week was that we did so much dissections. Fish, worm, and everything. I'm looking forward to do more dissections.

Blog#12 What surprised you from the worm's dissection?
What surprised me from the worms dissection is how stiff the worm was. I thought worms were easy to kill and open because they look so fragile. They are squishy too so thats why i thought it would be easy to dissect. The worm was pretty big as well i never knew there were worms that size. It was a harder dissection project then i expected.

Get a picture of alternation of generations put it in your blog and explain how it relates to plants
The relations of alternation of generations to plants is compared because it goes through the steps of how a plant grows. The female gametes, male gametes, mitosis, and fertilization all relate to growing a plant. It goes through haploid generation and diploid generation. Its like a cycle it just goes around thats how plants are grown.

Why is dissection an important part of a biology curriculum? Which animals and/or plants should be included in biological studies?
Dissection is an important part of a biology curriculum because it lets you learn about the insides of an animal. It gives you the experience to see how the body structure of an animal is. Animals that should be included to the biological studies are frogs and the plants are grass because those are normal to dissect on. The biological studies are those that should be included in.

Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each
Bees competes to get honey.
Commensalism -one benefits but the other is neither helped or harmed
Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each
Competition
Interaction that can occur between individuals or species as they attempt to use the same, limited resources, particularly energy, nutrients or space
Bees competes to get honey.
Mutualism -beneficial to both species
Actually a two-way exploitation. Food is beneficial to both species.
Predators
Predators kill and eat other organisms
Spiders kill bees to eat. 
Parasitism - one organism benefits by feeding on another
Fungus 
Commensalism -one benefits but the other is neither helped or harmed
Birds using certain trees as roosting sites or barnacles attaching to the skin of a whale

Why are the gases on earth getting trapped? Why is there global warming? Is it true there is a layer on the sky that traps all the gases and bounces back to earth? How do we stop global warming? Do we need to make an effort to try to save earth before everybody dies? We need answers as soon as possible.

Blog 7 Compare and contrast two biomes describe them in detail include pictures of plants and animals you are likely to see.
Terrestrial (land) biomes and Aquatic biomes (including Freshwater biomes and Marine biomes) are the type of biomes I'm going to compare. The marine regions are divided between coral reefs, estuaries, and oceans. Biomes are often named for their predominant vegetation, and all have certain characteristics such as microorganisms, fungi, and animals which have adapted to their particular environment. Terrestrial is land animals that live on earth land. Like the desert or any wild place. Any forest mountains anywhere.

Blog #6 Which level of a food pyramid is the most important? Support your answer
Blog #6 Which level of a food pyramid is the most important? Support your answer
I think the vegetable group is the more important group of the food pyramid. Too many people eat the meat group and don't care about the veggies. Its important to balance everything out so you'll be healthy. Too much of one thing is not good for you. You need everything. That means the fruits and stuff too. And people rarely think about the veggie group all they care about is the steak and good meat.

There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?
I think humans will be the 6th because i know we cant last forever. Its impossible. Something bad will always happen. Lets say a meteor can destroy earth. Or the earth will overpopulate. Global warming is also a big impact too. There are things we cant stop sometimes. I say our biggest factor is global warming.

Describe the three types of selection: directional, stabilizing and disruptive and give an example of each in your own words.
Stabilizing is when natural selection works against the two extremes of a trait to make the population more uniform. Stabilizing selection might work on the birth weight of human babies to keep them at an intermediate weight, because babies that are too big or too small have less chance of being born healthy.
Directional selection is a type of selection works to select the extreme of one trait. In a population of plants, flowers with the brightest color are selected for in order to attract the most pollinators.
Disruptive type of selection selects against the mean of the population.If there are two types of seeds to eat for a population of birds, either of two different beak shapes (sharp or blunt) might be selected for, but a beak that's the average of the two shapes might not be particularly good at eating either seed, so it would be selected against.

Blog # 2 Why is fossil record hard to interpret?
Fossils are hard to interpret because they take long time to form. Takes hundreds or even thousands of millions of years to form one. Thats why fossils are so rare and expensive. They're hard to find also since most of them vanish or is bury deep. The animals that are extinct are the ones we learn from. Like dinosaurs they're hard to find.

Microevolution is a change in gene frequency within a population. It is evolution resulting from a succession of relatively small genetic variations that often cause the formation of new subspecies. There are 5 ways microevolution can occur: mutations, selection, migration, genetic drift and nonrandom mating! Thats what microevolution is and how it occurs.

Semester 2: blog 1
Why is the theory of evolution still a theory and not a law?
Theories can NEVER become laws. And laws can NEVER become theories. A law is a fact. A theory is an explanation for facts. A theory is an EXPLANATION for observed facts. A good theory explains many facts. A law is a fact that is observed to be universally true. Note that laws are OBSERVED to be true, not proven to be true. A LAW DESCRIBES A FACT. A THEORY EXPLAINS MANY FACTS.

LAST BLOG OF SEMESTER
What was you favorite activity/topic this year? Why was it a favorite?
My favorite activity this year was burning the chips , it was a lab. It was my favorite because i got to eat the chips and burning things are fun. My favorite topic was about DNA fingerprints. It taught me a lot about fingerprints and what types there are. My least favorite was when we did the kim chi. It smelled like crap real nasty i didn't want to touch it. If i could change one thing i would change how we don't read the books because they are boring.

DNA changes
DNA changed how we investigate crimes because of blood and fingerprints. It can show who has been here and detect the criminal or show who has been killed. The 2 main tests are blood tests and fingerprint tests. DNA has helped us solve lots of crimes especially the methods where they look for blood cells or fingerprints. It has changed the world a lot.
