Biology

zzz [600]3 years ago

Answer:

The correct answer will be option A-the accepted model of the atom was changed.

Explanation:

J.J Thomson discovered the electrons by cathode ray tube experiment in 1897 and realized that the accepted model of atom as proposed by the Dalton has problems as he stated that "atom is indivisible".

The discovery of sub-atomic particles-electrons in his experiments showed that the atom can be divided into sub-atomic particles and he proposed the pudding model of the  atom which changed the accepted model of atom at that time.

Thus, option A-the accepted model of the atom was changed is the correct answer.

Blood flows through an artery that is partially blocked. as the blood moves from the wider region into the narrow region, alternately increases and then decreases.

<h3>What is the purpose of blood flow in heart?</h3>

The removal of positive charge by electrochemical gradients causes the membrane potential of the cell to shift more strongly in the direction of the equilibrium potential for potassium.

The membrane would become more negative as potassium permeability through the membrane increased. Given that potassium is a positively-charged ion and that the intracellular environment has a net negative charge, enhancing the membrane's permeability would result in a more negative membrane.

For instance, the amplitude of the potassium concentration gradient across the myocyte decreases as the external potassium level rises, lowering the resting membrane potential.
