Essay On Osmosis/Diff....

EQ: A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.
Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved. (Be sure to clearly state the principles addressed in your discussion.)
A)     My way of arranging this lab, first I would collect the needed materials. Second, create a question to go along with the experiment. Then I put each flask in a tube and tie it. Afterwards, I would place the flasks in separate cups. In that case, make a hypothesis/prediction (flask A is 0.2, flask B is 0.6, flask C is O.8 and flask 0.4). After that, add potassium iodide and wait 30 minutes.  Make observations. List errors in the experiment, state if your hypothesis is correct or incorrect.  
B)  0.2, 0.4 are weak solutions; therefore they would go through osmosis, going from low to high concentration. 0.6, 0.8 are strong solutions would undergo diffusion, going from high to low concentration.
           C)

Osmosis/Diffusion

 In AP biology we talked about Osmosis and Diffusion. Osmosis and diffusion are the very simular. Osmosis is diffusion that happens in water. We tested  two themes using bags and different solutions . We joted down the changes after each solution went through diffusion or osmosis. The lab we completed was dealing with a few different molars. Students used  tubing to hold the Glucose/Starch solution. Then tubing was placed with the solutions. Over time the water changed color. This responce clearly showed that though the process of osmosis, the glucose/starch solution transported itself to the water solution that surrounded it.

Reflection for Cellular Respiration

 This week's lab we learned more about cellular respiration. We answered questions that went along with the lab. I know a lot about this process but I gained more insight. From this experiment, I learned that Cellular Respiration undergoes 3 important steps; glycolysis, oxidative phosporalation and kreb's cycle. I recalled that respiration is the creation of energy due to the forming of ATP from molecules.

Creation disproves Evolution... Not finished

--Intro--
Was life created? Or did it evolve?
Is there a creator involved? Or did life randomly appear over a long period of time?
There is proof that there is a designer behind life.
There also is evidence that things evolved.
Keep in mind that "evidence" is not the same as "proof". Evidence is helpful in drawing a conclusion.
Proof concludes the matter altogether.
Everyone has their own opinion. What is the basis for that opinion? People can believe whatever they want, but that doesn't make them right.

Evolutionists believe that everything evolved from something. They believe that humans are naturally improving. They think that WE evolved from animals, causing us to act like one. Let;s see what Creation has to say about this.
Proof of Creation
First lets use our senses--hear, feel, taste, see and smell. Observe creation, look at the trees, different animals, variety of plants. Smell the fresh air or a nice flower. Taste your favorite food or drink. Listen to the ocean or to a dear friend or loved one.
Now think about some of the cycles of life. Like photosynthesis- trees need carbon dioxide and provides oxygen. Through Celluar Resipration WE need breathe out carbon dioxide and need oxygen to live. Thats harmony! Theres intelligence behind that. Now, Do you think this happened by chance?
 Examine earth and the sun. Now the earth is perfectly placed and tilted towards the sun. If the earth was even slightly moved in any direction, life would not be possible here! Also, the Ozone layer- it protects the earth from meteror rocks and many other things. This couldn't just happen from nothing. There is a Creator no doubt about it.
 Evolutionists teach that Life came from non-living matter- then that one animal reproduced by itself, then other animals evolved.Look at yourself, do you think your ansestors evolved from some animal. The difference between humans and animals is that humans want to find answers. WE want to know whats the purpose of life. WE ask alot of questions? Also, WE have a conscience and know right from wrong. Animals do NOT! Creation is not based off of religious premise, its common sense.  Christians are not the only ones who believe in Creation, in fact many scientists can prove it!
Our DNA(genetic makeup) alone proofs the is a designer behind creation. Who you are, what you look like, your personality traits, how tall you are, your skincolor, the foods you like etc... comes from your DNA! Think, no... really think about it-- its amazing! Thats just the basic concept of DNA. There is so much more to it.
If you believe in the Bible...the Bible clearly says that the everything was created by God. The Bible is not a science book, yet it is scientifically accurate. There is no scientific evidence that contradicts the Bible. (Additional proof  http://www.clarifyingchristianity.com/b_proof.shtml)

Since we can prove the Bible is true, it makes sense to find out what the Bible tells us about how life was first created and how we got here. If you were to open your Bible and read the first verse it says at Genesis 1:1   " In [the] beginning God created the heavens and the earth." Then to go in further detail in verse 24,25 --And God went on to say: “Let the earth put forth living souls according to their kinds, domestic animal and moving animal and wild beast of the earth according to its kind.” And it came to be so. And God proceeded to make the wild beast of the earth according to its kind and the domestic animal according to its kind and every moving animal of the ground according to its kind. And God got to see that [it was] good --

Evolution teaches that animals evolved over millions of years, making different types of animals and then finally evolved into humans.

God created every living thing according to it's kind or specie. Therefore man couldn't have evolved from animal. To back that up verse 27 ----And God proceeded to create the man in his image, in God’s image he created him; male and female he created them----WE have Godlike qualities, we don't actually look like God, he's a spirit. For example, 1John 4:8 says"God is Love". Since WE are possess his attributes WE love others and want to be loved back. See! God created humans seperately. Genesis 2:7 says" And God proceeded to form the man out of dust from the ground and to blow into his nostrils the breath of life, and the man came to be a living soul." After God created Adam he created Eve...PAY CLOSE ATTENTION!!! Genesis 2:22-24 says
---And Jehovah God proceeded to build the rib that he had taken from the man into a woman and to bring her to the man. Then the man said:“This is at last bone of my bones And flesh of my flesh.This one will be called Woman,Because from man this one was taken.” That is why a man will leave his father and his mother and he must stick to his wife and they must become one flesh."
ASTOUNDING! This is why women have two more ribs than a man! FACT.
..........More

Let's get off earth for a second and think about space. Now, if there was no creator... why would there be stars, how did they come to be? The Big Bang theory doesn't explain it. What about all the other planets, evolution isn't the answer because evolution isn't correct. It's an imagination. It's complicated, creation is simple. Evolution is impossible, creation happened. Believing in Evoution is like, gathering ingredients for a recipe for chocolate chip cookies, put them in a bowl, throw it in the air and expect fresh baked cookies! 1,2,3 blast off.

Genesis 1:3-5 says--- And God proceeded to say: “Let light come to be.” Then there came to be light. After that God saw that the light was good, and God brought about a division between the light and the darkness.And God began calling the light Day, but the darkness he called Night. And there came to be evening and there came to be morning, a first day.--- WOW!! These verses explain themselves. Theres more... verses 9 -14 goes on ---  And God went on to say: “Let the waters under the heavens be brought together into one place and let the dry land appear.” And it came to be so. And God began calling the dry land Earth, but the bringing together of the waters he called Seas. Further, God saw that [it was] good. And God went on to say: “Let the earth cause grass to shoot forth, vegetation bearing seed, fruit trees yielding fruit according to their kinds, the seed of which is in it, upon the earth.” And it came to be so.  And the earth began to put forth grass, vegetation bearing seed according to its kind and trees yielding fruit, the seed of which is in it according to its kind. Then God saw that [it was] good.  And there came to be evening and there came to be morning, a third day.--- These verse are clearly stating that GOD created the earth, every body of water, seas were an example. GOD created grass, vegetation, trees and more.

Setting Up for Success

The reason i enrolled in AP Bio is because i wanted to challenge myself and find more about life. I expect a lot of work and fun intersting labs. I also believe I will gain knowlege and become wise. One goal is to get good grades and pass the course.
Help from teachers and peers will make me progress. Also studying vigoriously and being prepared for class. This website can keep me posted about what i need to know in order to keep up with Biology and to express anything that comes to mind.

Ap Bio

Yay i set up my Blog for biology ,
