I am going to need to do something about this person he keeps mocking me and I ain’t having it. I don’t want them to find out but to be the best I can be I need him to disappear. I will just have to act normal but when the time is right he’s going out!

This is quite strange often the evil people(witches) will tell us the truth to make Us trust them and then afterwards they deceive us in our important times making us betray people which will give us big consequences

it is strange often in order to do us harm the witches tell us the truth about matters of small importance and then betray us in relation to something of imortance. Work done in class

Microscopes are useful in studying cell biology because it can magnify into an object that is underneath the scope and show its cells. The cells can then be examined by scientists and therefore it builds understandings of cells. The reason why it is really helpful is because they can zoom in up to 1000 times bigger than the normal size, if it was the normal size we wouldn’t be able to examine it but this way we can.

Magnification calculation formula: Length of object= Length of magnified object/magnification

Magnification is the ability to make small objects seem larger and Resolution is the ability to separate two objects from each other.

Advantages of light microscope: Simple to use, can view both alive and dead specimen, cheap to buy and low repair costs.

Disadvantages of light microscope: Poor surface view, low resolving power and low magnification.

Advantages of a electron microscope: Good surface view and internal details, high resolving powers and high magnifications.

Disadvantages of a electron microscope: Harder to use, user requires technical skills, can only view dead specimens, very expensive and expensive to maintain.

Single celled Prokaryotes are microbes that include bacteria, prokaryotic cells are much more simple then the more advanced Eukaryotic cell. Prokaryotes cells do not have a nucleus but instead has only a single chromosome. All Eukaryotic cells contain a Nucleus within the membrane. The difference between two cells is that one has a Nucleus and the other does not have a Nucleus. Also one contains a Membrane-bound organelle and the other does not.

Prokaryotes cells contains a plasma membrane, cytoplasm, cytoskeleton, ribosomes and a flagellum. The plasma membrane is a double layer of protein and other molecules, it holds everything in it together. The cytoplasm is jell like liquid that has all the cellular organelles within in it. A cytoskeleton provides structural support and also helps in the cell division. Ribosomes are tiny protein making machines of the cell. Flagellum helps the cell move.

Root hair cells and Palisade cells are specialized plant cells. Root hair cells are used for absorbing water and minerals from the soil for plants. Palisade cells are used for photosynthesis. Root hair cells have large surface areas which can be useful and palisade cells contain a lot of chloroplasts that help for maximum photosynthesis.

Lichens can be used as environmental indicators as they can only grow in places with clean air. They can’t grow in a place where the air is polluted with sulfur dioxide, therefore they can show us which areas are more polluted than others. Some types of lichens (Leafy and Crusty) can grow in places where there is pollution, however it has to be at a low amount. Bushy lichens are the only types of lichens that need really clean air. Lichens are unlikely to grow in places near roads as they are used by a lot of cars that release sulfur dioxide. The near roads the level of sulfur dioxide will high and so the air will be polluted. Yellow colored lichens are extremely unlikely to grow in places near roads as they need clean air to grow. Green and red lichens can grow in places near roads as long as the level of sulfur dioxide is low.

Fossil fuels are one major reason to why SO2 and CO2 is released in to the atmosphere. The way we can remove SO2 and CO2 from the atmosphere is by using several different methods such as solar panels to reduce the amount of fossils fuels being burnt for power. We can also use wind turbines which will generate electricity which means we would not need to use any fossil fuels which would reduce the SO2 in the air. The reason why would know it will be working is because Lichens would grow and when they do the color of their organism will be either green or yellow, yellow meaning the air is clean and if it is green then the air is slightly polluted. So by building these things in the countryside or on buildings(solar panels) you can reduce the amount of CO2 and SO2 in the air keeping it less polluted.

The merciless McDonald who is worthy as a rebel who attracts all swarms of villains to him but he was too weak and Macbeth who was a proud brave man sliced him up into half and put his head on a plaque.

Lichens are Plant organisms that can be used as Environmental Indicators because they sense air pollution especially the concentration of sulfur dioxide in the atmosphere. Lichens can be found in various different exposed places such as rocks and tree barks. They also need to be good at absorbing water and nutrients to grow there.

The Process of Natural selection according to Darwin’s Theory of evolution only the organisms best fit for that environment will stay alive and will start reproducing, making more of the same organisms to grow over the generations and the weak will be destroyed because it will not be fit for that environment. Natural selection is also the process of biological heritable traits becoming either more or less common in the population so it can develop the organisms fit for that environment. It is because of random mutation that these organisms get there beneficial genetics which then make them more liable to survive in the world. Also not always do these genes get passed on.
