What else can I help you with?
The reason that water soluble molecules cannot enter certain regions of the plasma membrane is due to the presence of?
hydrophobic tails of phospholipids in the plasma membrane, which create a barrier that repels water-soluble molecules. This limits the passive permeability of water-soluble molecules through the membrane.
Why is it important for the cell membrane to be fluid?
The reason why the cell membrane requires a fluid consistency is to allow certain molecules to pass through. Fluidity is also important for phagocytosis to take place.
What type of molecules can damage the ozone layer?
The molecules that damage the ozone layer are chlorine molecules. These molecules are the main destructive reason behind depletion.
Why is it that you can smell perfume several meters away give reason?
Perfume evaporates, the perfume molecules diffuse through the air and reach your nose, enabling you to smell them.
Is it possible to multiply air molecules?
Multiplication in its most literal sense applies only to mathematical operations performed on numbers, not on physical objects. Metaphorically, multiplication is sometimes used to refer to the process of biological reproduction, but air molecules do nor reproduce and are not alive. And sometimes multiplication just means making more of something - my problems are multiplying. It is not impossible to make more air molecules, although there isn't a lot of reason to do that, since the Earth already has a suitably dense atmosphere. The planet Mars could use more air molecules, though.

State one possible reason a certain substance can not pass across a cell membrane?
The cell membrane is selectively permeable. Some substances like molecules are too big to pass through the membrane. The membrane allows passive transport of moleculesÊ by filtration, diffusion, or osmosis.
State one reason why chromography is very effective for this type of analysis?
What type of analysis? Chromatography is the separation of molecules based on how they react in a passing mobile phase through a stationary phase and separating the molecules.
What is the reason behind ozone hole?
The main reason behind ozone hole is the reaction of the chlorine molecules from CFC's. These molecules initiate a chain reaction which then destroy the ozone molecules to form the ozone hole.
What are some issues with ozone depletion?
Ozone depletion is the process of thinning of ozone molecules below a certain concentration. The main reason behind ozone depletion is the excessive use of CFCs.
How does sharks excrete waste?
Sharks excrete their urea through their skin. Hence the reason why they have a certain 'ammonia-like' kind of smell.
What type of molecules can damage the ozone layer?
The molecules that damage the ozone layer are chlorine molecules. These molecules are the main destructive reason behind depletion.

Polar molecules behave as though they?
possess a separation of electric charge, with one end being slightly positive and the other slightly negative. This results in interactions with other polar molecules, such as hydrogen bonding, which can influence their physical properties such as solubility and boiling point.
Why do bottlenose dolphin live in the ocean?
Because god out them there for a reason and the reason is certain
