cell membrane- Controls the movement of substances in and out of the cell

cell wall- The cell wall is the shield of the cell. Essentially the rib cage

nucleus- The nucleus contains genetic material, which controls the activities of the cell

chloroplast- Contain chlorophyll, which absorbs light energy for photosynthesis

mitochondria- The energy from the cell is released by respiration

vacuole-  Filled with cell sap to help keep the cell healthy

Natural selection is when an organism has a mutation which allows it to get more resources such as: food and water. The mutation will let the organism defend its self and in total live longer. This allows the organism to have offspring. The offspring will carry the mutation and again be able to live longer and have children. When all the organism that have not advanced die out it is then that evolution has happened.

Jackson was walking home at 12 o’clock at night.  He usually strolls home in the cold at night feeling fine, However this night Jackson was walking at a steady pace. Just about running. This night with the fog curling up all around it felt mysterious. Dangerous. Jackson felt as if the cold was stalking him. wrapping him up in its cold hands. When Jackson walked further he felt something he hadn’t felt in a long time. he wanted to run into the nearest building and curl up in a ball.

While Jackson  thought this, he soon realized that he was on his front porch. Jackson put his key in the door and began turning the key. As Jackson was doing this he felt as if he was being watched. Being stalked. As if he was a burglar in his wife’s house.When Jackson put his hand on the door handle there was a banging noise. he looked up. the shutters were were open and the net was swaying in the gentle breeze.

As Jackson was staring at the net something or someone moved. There was something in the house that felt different. It felt like something was there. Living. Jackson was just looking at the window expecting to see his friend jump out and scare him. His pocket watch struck 12:15.the night started to lighten, but still gave the house a sense of mystery. He realized that less then twelve hours ago his wife’s funeral had taken place. Finally Jackson went into the house. When he stepped in to the house way he felt as if his dead wife was present. watching him. stalking him. As he stared at the rocking chair where she would always sit, he felt empty.

Jackson went to the fire place and started a fire. when he finally got a fire roaring, there was a gush of wind. An object swept by taking the fire with it. The went dark. Jackson looked up. there was a rattle of chains, a creak of the floor board, the sound of something walking down the stairs with a step every minute. cautiously Jackson slowly walked up the stairs ready to meet this intruder. Slowly Jackson felt dizzy and weak with every step. His foot missed the 5th step and Jackson fell.

The church bells rang 1 o’clock. only then did Jackson open his eyes. He was feeling weak but was welcomed  to a huge luxury fire, with the shutters and net pulled back into place. Jackson ran a hand through his hair. His chest felt tight. his head was screaming GO, GO. He felt scared. Not terrified. Just scared. He felt as if the intruder was close to him. Not the feeling to runaway, in fact he now felt the need to stay.  Then something happened. There was another hand on his head. cold and death like. It was there. Not a figment of the imagination. It was there. Jackson got up and turned. the figure moved back into the moonlight, and he saw her. The warm smile on her face, her blonde hair swaying in the moonlight, her blue eyes shining, but her skin colour was grey. Grey like a decomposing body. Grey. She was wearing a Grey dress yet we buried her in black. Jackson, was drawn to her. Compelled to stair. As Jackson stared, he felt himself wrinkle. Jackson fell. When he was on the ground he stared at his hand. Grey.

A microscope is a device which we use view and study objects that are not visible to the us with out a device to enhance our eye sight. The parts of a compound microscope are as followed: the eyepiece, the ocular lens, the objective lens, the stage, a condenser,  the condenser adjustment control, the microscope light source, the light switch control, adjustment knobs and nosepeices

One of the features of a microscope is that it has the  ability to enlarge images on a slide. Magnification is provided by a two-lens optical system consisting of the ocular and objective lenses. The ocular lens is on the eyepiece while the objective lens is attached to a rotating nosepiece. Typically, the nosepiece contains four objective lenses, with each lens corresponding to different levels of magnification. The combined magnification of the ocular and objective lenses is the total linear magnification of a microscope. A compound microscope is capable of enlarging an image from 40 to 20,000 times its original size.

Another basic feature of a microscope is its resolving power, otherwise known as the resolution. The two factors that affect the resolution are the wavelength of the light source and the numerical aperture. Electron microscopes provide better resolution and show more detail compared to light microscopes.

The reason microscopes are useful when you study cells in biology is because microscopes allow scientist to look at cell structures and molecular structures.  microscopes enlarge small  cells on a silicon chip and allows you to see what is on the slide through lenses. Doctors use microscopes as well so they can look at blood cells and tissue so they can make a correct diagnosis.

calculating total magnification

how to calculate total magnification is not as hard as you may think. to calculate the magnification is that you take the lens power, usually 4x, 10x, 40x, and simply multiply the power of the eyepiece which is normally 10x.

this is a image on how you can calculate total magnification

HOW TO USE A LIGHT MICROSCOPE

                                                                                                                                                                                                                                                 Rotate the moving lens with the lowest power has been put into position

  Put the slide with the object you want to see on the stage and hold in place with the microscopes stage clips

Take a look at the side through the lens and use the focus knobs so that the stage stage moves up and down. When you look through the lens move the focus knob so until you have a clear image

Adjust the condenser and light intensity for the greatest amount of light.

Move the microscope slide around until the sample is in the center of the field of view

twist the focus knobs so the sample is in the focus and adjust the the condense rand light intensity for the clearest image 

When there is a clear image of the sample, with the lowest power objective, you can then switch to a different lens

when you have an image of your sample you may have to readjust condenser and light intensity. If the image of the slide is not in the focus you will have to readjust the the knobs and the light. if this does not work you may have to use a higher power lens. Do not let the objective lens touch the slide.

the relationship between online text and spoken language is that both mean the same thing its just that one is easier to read then the other. when children or teenagers use text speech(textism) and sometimes the text can be unclear on just unreadable. when adults text some use textism while others use formal language. the style of the text can be chatty of just straight forward getting to the point. An example of my texts just being plain would be this.” On train. No hwk. Bye” and this is an example of me being chatty” r u gonna b on the train. Did u see the football game. I will text you the score l8r.” As you can see there is a clear change of formal language when i am talking to my mum and when i am talking to my friend. When i am talking to my mum i am more formal and less chatty. The reason i think i do this is because when you talk to your mum you are less likely to use textism because your mum is more likely to not understand what you are saying. My friend who was using textism is more likely to understand because he is a ‘digital native’ while my mum is a ‘digital immigrant’. the difference between a digital immigrant and a digital native is that a digital immigrant is someone who was alive before textism and i-pads and laptops and touch screen phones. a digital immigrant is more likely to not understand textism and will be very confused and stressed around new technology, while a digital native is someone who grew up around technology. i am a digital native because i am someone who grew up in the rise of technology. the reason that i have included this in this essay is because this has an affect on how the language is different because digital natives understand text slang. this is basically how people text now. the way how people talk is utterly different except for the few kids that talk how they text. for example some say “totes” instead of totally. this may be because the way they text may be effecting how they talk. moving aside from that when most teenagers talk they use slang such as ‘fame’. when teenagers text they use textism and teenager talk using slang. when adults text they use formal language and when they talk adults use formal language as well. this is interesting because if adults use formal language for text  and for talk, then why do teenagers use two different forms language to speak to another person? what i think to the question i have proposed would be that we are in an age of technology and that we are picking up the way that few started to now having used all over the world. because we are teenagers we

 The equipment I will use in this practical will be:

A clamp- The reason that I’m using a clamp is to hold the ruler steady so that I can drop it at the same height

Clamp stand- The reason that I will use a clamp stand is that the stand will be able to hold the clamp when it is screwed onto the stand

a metal lab grip- By using this I can have the clamp stand and the clamp screwed onto each other with this simple mechanism

A 1 meter wooden ruler- By using this I can drop the paper helicopter at the same height so the test will be accurate and fair

Stop watch- This will allow me to time how long it will take the helicopter to fall to the ground

And a paper helicopter- Now this is what I will use to test my hypothesis

the reason why I have chosen this equipment for this experiment is because the clamp will hold the ruler  in the same place so I can drop the paper helicopter at the same height so that the experiment will be accurate. The reason that I’m not using a person to hold the paper helicopter is that a person will change the length of the drop when we drop the helicopter so I comes an experiment which is not accurate

I have named my equipment and justified my choice in the equipment but I haven’t actually named my idea. So hear it is.My hypothesis is to change the length of the helicopter blades so it will go through the air with a larger surface area cutting more air so that it is propelled faster.

I woke up at the break of dawn in the pitch blackness of my cave with my two sisters either side of me. I woke my sisters by shaking them roughly and then my daily routine starts with my sister Hex saying ‘should we summon our mistress Hecate the Goddess of black magic?’ I replied to hex ‘Yes we should summon  our mistress, after breakfast.’ I used my Black magic to open the cupboard to make a jar of gruel levitate to me. I open the jar and poured the mixture in my cauldron to cook. After a while I dip my chipped wooden bowl into the cauldron and I eat what is in my bowl with my wooden spoon.

I change into my dirty brown dress, then i put on my black apron. We then hold hands and dance around the cauldron saying ‘Hecate, Hecate, come, come to us,  we need our ordes for the day’. Hecate pops out of the cauldron with a scream shouting’who dares summon me’? I speak out first saying ‘Hecate,Hecate, what are our orders for the day’?

After we are givon are orders we go outside and climb upon our broom stick’s. While  flying high t say to Hex ‘finally we get to  punish the Mortals for imprisoning Hecate’

After awhile we stop at our first of many villages to terroize. We turn the cows milk sour turn the cheese mouldy and kill the pigs. we put a spell on the chickens, now they will never lay eggs. HA HA!

At the next village we make a big thunderstorm and control the rain and lighting. this will frighten them. HA HA!

At the next village we break into the village and make the food disappear to our cave. HA HA!

we fly back to our cave for a feast. Then we fly out to the port and cause a large Tempest. It destroys the boats with it’s high winds, sharp lighting, sets the port on fire. The ships have all sunk and heavy rain pours and floods the cargo hatches.HA HA!

We fly home happy with our days work and summon Hecate again, we give a full report, she is pleased we have done her bidding.

After supper, I go to bed on my pile of hay, happy with our work to day, but my body aches like all the other days!

“Sometimes there are demands for more homework, as a part of a drive for higher standards”

The sentence structure is relativity long and is split up into two separate simple sentences. The grammar is simple with only a comma.

“At other times there are calls for less homework to be set”

This sentence is the complete opposite to the first one as it is a complaint for less homework not more. This is another simple sentence with no grammar.

“American studies report the amount of homework being set for younger students doubling over the past twenty-five years or so, although some doubt these findings”

This sentence talks about homework doubling over the past twenty-five years but then the author brings in some views within the public. This brings a balanced view so you do not change your mind straight away. This is a long sentence and not a simple sentence unlike the others. Like the second one it has a comma to divide the sentence up
