Blog #6 Which level of a food pyramid is the most important? Support your answer

For the food pyramid of the organisms, I think the producer is the most important level out of all the organisms.  The producer can produce their own food from sunlight.  Therefore they can grow and reproduce by themselves.  Other than that, many insects and animals feed on plants to survive.  Without the producers, all these animals and insects will die and extinct.  And as this extinction moves on, all organisms will be extinct because of the lack of food sources.  Therefore, the producer is the most important part of the food pyramid.

Blog #5 There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?

I think humans are impacting the 6th extinction.  Human's advance technology is casing a lot of pollution and is invading the natural environment of the species.  As trees gets cut down and pollution spreads around the world, a lot of species will be extinct.  Globe  warming and pollution will eventually led to the 6th major extinction in Earth.

BLog #4 Semester 2

Blog # 4 Describe the three types of selection: directional, stabilizing and disruptive and give an example of each in your own words.

 Directional selection is a type of natural selection where certain gene is used and more favored. It becomes apparent in each generation and removes mutation from a population.

Stabilizing selection is a type of natural selection where the genetic differences reduced through generations due to a trait that has been more favorable than the reduced genes.

Disruptive selection is the a type of natural selection in which there are two favorite genes and one of them is more favored than the other, resulting into two distinct groups with two distinct features yet from the same ancestry.

Blog #3 Semester 2

Explain what microevolution is? What are the three ways that variation occurs?

Microevolution is evolution, or changes, in gene frequency that responds to a population. The three ways that the variation can occur is through mutation, natural and artifical selection, and genetic drift.

Blog # 2 Why is fossil record hard to interpret?

Many fossils are thousands or million years old.  Some of the fossils are broken and only some parts of the fossil is not damage.  In this case, it is very hard to inerpret the fossils if the fossils is not in one piece.  Sometimes, sand and dust can also damage and cover some parts of the fossils.

Blog #1 Semester 2

Why is evolution a theory and not a law?

 Evolution is the change over time in the proportion of individual organisms differing in one or more inherited traits.  The evolution is a theory because there is not enough information to prove how the evolution started.  No one knows how the first cell in this planet is created.  Therefore, the evolution can only be a theory.

What was you favorite activity/topic this year? Why was it a favorite?



My favorite activity of this year is the chip burning lap.  I like it because we can burn chips and eat the left overs after.  It was very fun except the fact that we burn the chips out in the sun.  It is very HOT!

What was your least favorite? Why?

I think learning about cells is my least favorite topic.  I am not very interested in cells and I don't know much about it.  A lot of the notes on it is hard and I have to try very hard to get it.  Therefore, I think cells is my least favorite topic.

If you could change one thing (Not the amount of homework) what would it be and how would you change it?
I think the points Ms. Malonek gives to my notebook is too high.  When I'm trying to calculate the points, I get very dizzy and crazy because the number is too big.
