A resource, such as oil, that cannot regenerate in a reasonable amount of time, such as a human lifetime, is called a "nonrenewable" resource.<em> (A) </em>
Once it's gone, it's gone.
Answer:2 m right
Explanation:
Given
First child is sitting 1 m left from Pivot point
Mass of second child is half of first
Let mass of first child be m
Second child 
In order to balance see saw torque must be zero about pivot

x=2 m right from pivot point
Answer:
At the dimer-dimer interface there might be acting non-covalent forces (van der waals, Hidrogene bridges, hydrophobic forces)
At the monomer-monomer interface there might be covalent forces acting (disulfide bridges).
Explanation:
On the SDS-PAGE application works by disrupting non-covalent bonds in the proteins, and so denaturing them. Therefore, the disulfide bridges won´t be disrupted, so the monomers will remain bounded.
A proton consists of 2 up quarks and 1 down quark.
A neutron consists of 1 up quark and 2 down quarks.
A deuterium nucleus consists of one proton and one neutron, so its quark composition is (3) 3 up quarks and 3 down quarks.
To solve this problem we will apply the concept given by the law of gravitational attraction, which properly defines gravity under the function

Here,
G = Gravitational Universal Constant
M = Mass of Earth
r = Distance between the human and the center of mass of the Earth
The acceleration due to gravity when is 4 times the mass of Earth and 3 times the radius would be given as,




The weight is defined as

So the new weight would be given as






Therefore the weight under this condition is 288.8N
