all animals need food and the start of the food web starts with sunlight. sunlight gives energy to plants, the plants grow and bugs land on them, then bird eats the bugs, then the bird gets eaten by and land animal, then the land animal gets eaten by a bigger one, then he dies and give nutrients for plants to grow. the thing that all life needs is sunlight. then evolution has made it so all living things can survive today. so if it weren't for the sun life wouldn't exits.

my team study tubers (potatoes, onions, yams, and others like that) and tried to a potato clock. a tuber is a eatable root. Most tubers have many acids in them. they produce energy because they have all those acids in them it creates a chemical reaction between copper and zinc or magnesium. in our project we tried to make a potato clock. We couldn't get the clock to work with potatoes or with yams but we did create 4.0 volts. i was in-charge of studding why tuber produce energy. this is the website i used.

sexual reproduction is likely to have more diverse characteristics that asexual because in sexual you get gens from your mom and dad. if it was asexual you would be just the same as your twin

My friends and I did a test for bacteria in different places in the school. The questions we asked was what kinds of bacteria there are? where are the bacteria? is there bacteria in our school? we tested the door handle, toilet water, bathroom floor, porters door handle. are results showed that the bathroom floor had the most bacteria, then it was the toilet water, then it was the door handle, then the last was porters door handle. our research showed that the bathroom floor has the most bacteria. thank you for reading

1 How do cells divide? If a cell splits in half to become two cells how are both those able to work?
A1 The cell's chromosomes doubles themselves, then both of them move to differnt cell walls. The cell elongates and it's plasma membrane grows inward, then the cell splits! The cell divides and creates two twin cells. Those twin cells are able to work because the mother cell gives them everything they need to produce and survive.
Q2 Write a brief description of what is happening at each of the seven stages of cell division starting with Interphase.
A2: 1. Interphase- This is the longest part of the complete cell cycle. The cell is very active while the DNA replicates, centrioles divide, and proteins are being made.
2 Prophase- During the first stage of mitosis, the nucleolus fades and replicated (copied) DNA and associated proteins, also called the chromatin, condenses into the chromosomes. Each one of these chromosomes has two chromatids, all of those chromatids have the same genetic information. The microtubules of the cytoskeleton also disassemble.
3 Prometaphase- the nuclear envelope collapses in this stage so there is no longer a recognizable nucleus. Some spindle fibers connect to chromosomes, but others elongate and and overlap each other at the cell center.
4 Metaphase- Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell.
5 Anaphase- Spindle fibers shorten, the kinetochores separate, and the daughter chromosomes, also called chromatids, are pulled apart and begin moving to the cell poles.
6 Telophase- The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.
7 Cytokinesis- the spindle fibers that didn't attach themeselves to chromosomes start breaking down until only a small portion of the overlap is left. Also in this region, a contractile ring finally separates the cell into two sister cells. Microtubules in both of those cells then reorganize themselves into a new cytoskeleton for the return of cell interphase.

Animal Cells vs. Plant Cells

this project has tot me a lot, before i didnt know anything. Even thought they are different, they have many, many things the same. The only part that animal cells have that plant cells don't are centriole. Also, the only things that plant cells have that animal cells don't are chloroplasts and cell walls.The many things that plant and animal cells have in common are: nucleus, nucleolus, cytolsol, centrosome, golgi, lysomes, peroxisome, secretory vesicles, cell membrane, mitochondrion, vacuole, smooth endoplasmic reticulum, rough endoplasmic reticulum, ribosomes. they also have things that are not the same

Enviroments affect the Organisms by changin there habits and the way they move around. For instence The brine Shimp hached faster in sugar water than in salt water. That is how enviroments change the organisms.

I think that global warming hasn't effected anything yet. My reasons for that is that the climate is always changing and that it's just been warmer. my opinion is that more people panic about it the worse it will get. I think we could do thing to make us were helping by make cars with better gas mileage. Maybe that will make people panic less. that is what i think about global warming.

energy changes form stored energy into knanitic energy and then into motion or light. When you charge a battery you are adding more stored energy to the battery.

cispus was one of the most awesomist champs ever. when you are there you never get board there is always somthing to do. like you can go on hikes play volyball,football,or basketball. the ropes course is fun but make sher your arm is not heart. my favrit part of the ropes course is the tunle. when you are in the tunle it feels like your hiding from trols and giant. if you think you are big and then you walk up to the top of the stars and you turn aroud and look at mt.staint helens your mouth drops and you lose your breth your not alone. when you take the hike to angle falls it is awsome the huge trees sround you the best part is when you walk in the crator and water falls in front of you all you do is look. well thats all. thank you jacob.

Water Pollution Pamphlet
By Hadlei, Jacob, and Alina
In this pamphlet you will be reading about freshwater pollution and nitrates.
Plus you will also be reading about some main sources of freshwater pollution. You will also be reading about point and non-point sources of pollution. Have fun reading this pamphlet.
What is freshwater pollution?
Freshwater pollution occurs when waste products or other substances change the physical, thermal, chemical or biological characteristics of the water. Affecting living species and reducing the water’s beneficial uses. A river is polluted when a substance, which degrades the water quality, enters the water and alters its natural functions. Some sources of water pollution are farmers using fertilizer and it getting into groundwater and it getting into water. Also sewers sometimes run off into rivers, creeks, and/or lakes.
What are nitrates and are they bad?
A nitrate is natural compound in all ecosystems. It is one of the chemicals essential to plant life. Too much can be a problem for plants and animals. It is also a component of chemicals and manure-based fertilizers. So nitrates can be bad if there are too much of them in your drinking water.
How can WE prevent water pollution?
We can prevent water pollution by picking up after ourselves. For instance pick up trash on the side of the road when we go on walks. Or maybe recycling whenever we can. Reduce, reuse, and recycle as much as possible. Use chemical at least 200 feet away from main water sources. Those are some of the ways we can prevent water pollution.
How do Nitrates get in the water?
Nitrates can sometimes enter water sources in areas of high fertilizer use. When too much nitrates get into water it can be harmful to plants and animals. Other ways that nitrates can get into water if there are high sewage use and feedlots near by. Those are some ways that nitrates can get into water.
What is point and non-point sources of pollution?
A point source is a specific source of pollution that can be identified. A non-point source is a wildly spread source of pollution that cant be tied to a specific point of origin. The difference between the two is that a point source CAN be identified. A non-point source CAN’T be identified easily. Those are point and non-point sources of pollution.
In this pamphlet you read about fresh water pollution. You also read about nitrates and how they affect us and plant life and animals. Plus you read about point and non-point sources of pollution. I hope you enjoyed reading this pamphlet of ours.
Thanks from,
Hadlei, Jacob and Alina
