The, it's electron goes for HIGHER orbital form lower orbital
THE ANSWER IS B THE CEASE TO EXIST WHEN LAVED IN LIQUDI hope that helped
Energy is the ability to do work so I would say that thermal or heat energy is a type of work. Don’t know if this will work but that’s what I would put.
Answer:
Adding a reducing agent
Explanation:
Homodimeric proteins are formed by non-covalent interactions between two identical proteins (monomers).
Some of these intermolecular interactions are mediated by disulphide bonds which can be broken by a reducing agent like beta-mercaptoethanol (2-ME).
By adding the reducing agent to the gel, it is probable that the dimer is broken and the band observed will correspond to the two identical 22.5-kDa monomers.
Answer:
The speed at the aphelion is 10.75 km/s.
Explanation:
The angular momentum is defined as:
(1)
Since there is no torque acting on the system, it can be expressed in the following way:
(2)
Replacing equation 1 in equation 2 it is gotten:
(3)
Where m is the mass of the comet, 
is the orbital radius at the aphelion, 
is the speed at the aphelion, 
is the orbital radius at the perihelion and 
is the speed at the perihelion.
From equation 3 v_{a} will be isolated:
(4)
Before replacing all the values in equation 4 it is necessary to express the orbital radius for the perihelion and the aphelion from AU (astronomical units) to meters, and then from meters to kilometers:
⇒ 
⇒ 
⇒ 
⇒ 
Then, finally equation 4 can be used:
Hence, the speed at the aphelion is 10.75 km/s.
