I fill like the reaction would be distillation or chromatography but distillation has to do with bioling points and chromatography has to do with how far the components separate along the material. but im in chemistry not advance placement.
Answer:
The energy in seismic waves that cause the ground to shake Heat energy associated with friction on the fault slip surface Gravitational potential energy (the energy stored when lifting something off the ground, for example) may change as a result of the earthquake Elastic potential energy, as in the recoil energy of a stretched spring.
Explanation:
Answer:
B• The hydrophilic phosphate groups of the phospholipid molecules are attracted to the aqueous internal and external environments.
Explanation:
Hello, you did not put the model to which this question refers, but I can say that the letter B is the correct answer, due to the composition that the phospholipids present.
Phospholipids are a molecule formed by two tails of hydrophobic fatty acids, that is, they do not come into contact with water, and a type of "head" that is a hydrophilic phosphate group, that is, it allows contact with water.
When a molecule formed by phosphate groups is found in an aqueous medium, it is common for the hydrophobic tail to be attracted to the inner corner of the molecule, preventing contact with water, while the hydrophilic part faces the outer side of the molecule.
Answer:
2y=8-x
y-2x=-1
y-2x=-1
y = 2x-1
Substitute for y in the 1st
2(2x-1)=8-x
4x-2=8-x
5x = 10
x = 2
y=2x-1
y = 3
Explanation:
2y=8-x
y-2x=-1
------------
Rearrange:
x = 8-2y
y = 2x-1
------------
Substitute to get:
y = 2(8-2y)-1
y = 16-4y-1
5y = 15
y = 3
-------------------
Substitute to solve for "x":
x = 8-2(3)
x = 2
