In the context of the neural impulse, the membrane that encases the axon is called semipermeable because FLUIDS CAN SOMETIMES FLOW INTO OR OUT OF IT.
Semi permeability is the ability of the membrane to allow certain substances, not all, to pass through it.
Answer:
In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many <u>hydrogen</u> bonds
Explanation:
In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.
Answer:
because of how close and far a location is from the sun
The symbol C represents Carbon.
CaCO₃ ⇒ CaO + CO₂
Calcium carbonate is a compound which comprises of elements such as :
<h3>Compound</h3>
This is formed from the combination of two or more elements in a chemical
reaction. In this scenario, the elements are combined in varying proportions
to form the compound.
Carbon is an elements which is denoted with the symbol C which makes it
the appropriate choice.
