What sort of surfaces do the inner planets have?
The inner, or terrestrial planets are more dense than the outer planets/gas giants/jovian planets. Through a process of differentiation we find inner planets to typically consist of a molten iron core and a less dense silicate crust.
Why do planets appear to move through the background of stars?
planets are much closer to us than the stars
The planets appear to move through the background of stars because?
planets are much closer to us than the stars
The belt of constellations through which all the planets move is called the?
The belt of constellations through which all the planets move is called zodiac. The true shape of the planetary orbits was discovered by Kepler.
What are the 2 motion that all planets go through?
They orbit and they rotate
After DNA is cut with a restriction enzymes how is the mixture of DNA fragments sorted?
Through the process of gel electrophoresis.
What is the purpose of an atom smasher?
To smash atoms together really fast. The resulting fragments are then analysed through sensors to determine what happened.
What is the dropping or settling of eroded materials?
The process by which material is dropped or settles is called deposition. The deposition of rock fragments leads to the formation of sedimentary rocks through the process of lithification.
What are Cell fragments that prevent blood from leaking through capillaries?
Platelets are cell fragments that prevent blood from leaking through capillaries
What sort of surfaces do the inner planets have?
The inner, or terrestrial planets are more dense than the outer planets/gas giants/jovian planets. Through a process of differentiation we find inner planets to typically consist of a molten iron core and a less dense silicate crust.
What happens to rock fragments and other materials by water?
Given enough time, they may collect in sedimentary basins and form rock through a process of lithification.
Explain how an agarose gel can separate DNA fragments of different lengths.?
The separation of DNA fragments is based on size. When a DNA sample is run in a gel (electrophoresis), the lighter fragments migrate faster than the heavier (longer) fragments under the influence of an electric current. At the and of the process, the shorter fragments are found at the terminal end of the gel and the longer fragments closer to the origin
What is used to separate DNA fragments by size?
Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.
What can you infer about how what these meterorite fragments are made up of that can travel through space?
what can you infer about how and what thease meterorite fragments are made up of that can travel through space
What are pure PET fragments called?
Pure PET fragments are called PET flakes. These flakes are typically obtained through the process of mechanical recycling, where used PET products are sorted, cleaned, and shredded into small pieces before being melted down to create new items.
The rate at which large DNA fragments move through the electrophoretic gel is?
the answer to this question is that, its greater than the rate at which small DNA fragments move through the same apparatus
Where in the gel electrophoresis do you find larger fragments?
The larger the fragments the slower it migrates through the gel. Because it is bigger it takes longer to squeeze through the pores of the gel matrix. So the largest gel fragments will be at the top, closest to where the sample started.
