Answer:
So I'm sure this is the answer to the eauations
Answer:
The effective nuclear charge (often symbolized as Zeff or Z*) is the net positive charge experienced by an electron in a multi-electron atom. The term “effective” is used because the shielding effect of negatively charged electrons prevents higher orbital electrons from experiencing the full nuclear charge.
Explanation:
The conjugate base of ch3ch2co2h or propanoic acid would be CH3CH2COO- or propanoate. The conjugate base is what is left after an acid has donated a proton in a reaction. Hope this answers the question. Have a nice day.
Answer:
The correct option for question 1 would be:
a bilayer containing lipids with hydrophilic head groups pointing inward and hydrophobic tail groups facing the solvent (extracellular fluid and cytosol).
The correct option for question number two would be: proteins.
Explanation:
The membranes present phospholipids that act as selective barriers between the intracellular and extracellular space, allowing an internal balance in relation to the external one.
Its conformation is mostly phospholipids, fatty acids, proteins (from transmembrane to intermembrane or external)
Answer:
Rutherford's theory laid the foundation upon which Bohr's model is founded. Rutherford established the fact that at the center of the atom, there is a nucleus whose radius is smaller than the radius of the atom. This nucleus is positively charged and most of the mass of the atom is concentrated there. Electrons move round this nucleus in orbits.
The experimental evidences of the Bohr's model shows that Rutherford's model was fundamentally correct. However, Bohr's model introduced the idea of quantization of the energy of electrons in an atom. The model went further to explain the spectra lines of the hydrogen atom.
