The respiratory system
The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
oxygen+glucose carbon dioxide+water
In your lungs 🫁 78.09% are nitrogen and 20.95% is oxygen
There are small air sacks called aveoli
They have chambers in the aveoli
Your oxygen goes in them and comes out of them
Inside a cell there is the cell wall, nucleus and Cytoplasm
The nucleus is the middle part of the cell. It contains DNA
The parts of the microscope are the base, illuminator, eyepiece and the eyepiece tube, the focus knob and the lens.
You put the object you want to magnify under the lens then turn on the light and then you look through the eyepiece
Co2 and oxygen
specialized cells are parts of cells that have a specific job to do E.G. the nerve cell.
Diffusion is when molecules move in water for example when the water is frozen they stick together but when it is not frozen, they move around.
Heart 🫀, Brain 🧠,lungs 🫁, Intestines, Liver and Kidney, pancreas
Unicellular organisms are organisms with only 1 cell inside them.
Unicellular organisms have a reproduction system.
The cardiovascular system
The reproductive system
The digestive system
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The skeletal system
Air contains 78.o9% of nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon and other gases
Animal and plant cells have a nucleus
There are 2. Main. Cells
Blood cells contain oxygen and co2
