Answer:
The hydrophobic core of the membrane does not allow the charged particles to pass through it.
Explanation:
The inner core of the membrane is made up of hydrophobic fatty acid tails of phospholipids. Due to this, some substances such as large, charged and polar particles cannot cross the membrane. This is why Na+ with a positive charge cross the membrane with the help of transport proteins only. On the other hand, molecular oxygen (O2) has a small structure and does not carry any charge. Therefore, it can cross the membrane without any help of transport proteins.
An amino acid is a protein, there is 4 groups Carbohydrates, lipids, Proteins, sugars
The best answer would most likely be genetics or genetic theory.
There were many doubts about Darwin's theory because Darwin could not yet describe the mechanism of inheritance. Mendel's work on inheritance was already published, 2 years earlier, but this eluded Darwin. It was only till after Darwin's death that the science of genetics came about.
