Thomson's model of the atom was called the plum pudding model. He discovered electrons, so he placed them in the atoms. This was before the nucleus was discovered.
Now, the current model is an atom that contains a positively charged nucleus (with both protons and neutrons), and negatively charged orbitals with electrons.
Chiral center is the center where all the attached substituents are different. For example, a carbon is said to be chiral carbon if it is attached to four different substituents.
The structure of threonine is attached here.
The marked carbons are chiral carbons because they have all the 4 different substituents.
the movement of air parallel to earth’s surface is called wind
Answer:
Resting potential
Explanation:
The resting potential is the term used to the describe the difference in electrical charge across a membrane. Ion is solution are capable of carrying a charge so their presence in biological systems is of interest. Two factors affect the resting potential:
- the concentration gradients of the ions in solution across the membrane
- the permeability of the said membrane to the ions mentioned above
Answer: energy transfer
Explanation:
latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapor at constant temperature and pressure.
