what is a hierarchal relationship
the biological levels of an organism in a complex, multicellular organism, from smallest to larges units
what is the hierarchal relationship
The biological levels of organization in a complex, multicellular organism, from the smallest unit to the largest unit, are…
CELLS - TISSUES - ORGANS - ORGAN SYSTEM - ORGANISM
what is the respiratory system in animals
the function is to bring in the oxygen and get rid of carbon dioxide
digestive system in animals
the function is to absorb food and then excrete the waste products
prokaryotic
does not contain membrane
eukaryotic
contain a membrane bound organelle
scanning electron microscope
the purpose of the scanning electron microscope is a technique for obtaining high resolution images of biological and non-biological specimens. it uses biomedical research to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes
what do the basic units of life include
- cells are basic units of life
- all living this are made up of cells
- all cells come from other cells
formula for cellular respiration
C6H12O6 + 6O2 ——> 6CO2 + 6H2 O + chemical energy (ATP)
unicellular organisms
made up of only one cell that carries out all of the functions needed in an organism
multicellular organisms
multicellular organisms use many cells to funtion
specilised animal cells
features which have components that allow them a specific purpose (for example, red blood cells, muscle cells, etc)
low power
x10 (x10) = x100
high power
x40 (x10) = x400
total magnification
x100 (x10) = x1000
