A student wants to model the net movement of water into a cell using a semi-permeable bag, water, a large beaker and
salt.
W
Which setup could he use to model the net movement of
water into a cell?
O Place a bag containing a 10% salt solution into a
beaker containing a 10% salt solution
O Place a bag containing a 30% salt solution into a
beaker containing a 10% salt solution
O Place a bag containing a 20% salt solution into a
beaker containing a 40% salt solution
O Place a bag containing a 30% salt solution into a
beaker containing a 40% salt solution

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
