How are water and nutrients transported through bryophytes? What is a plant cell organelle that processes energy? How do water molecules move through the cell membrane during osmosis? Why are animal cells more irregularly shaped than plant cells?
During osmosis, which molecules move and through which type of membrane? What is passive membrane transport? a. the movement of a substance across a membrane without expending energy b. the movement of a substance across a membrane by expending energy c. the transport...
How are cells able to respond to signal molecules? What type of transport can move big molecules across the cellular membrane? How do carrier proteins transport substances across cell membranes? How do water molecules move through the cell membrane during osmosis?
Water. At its most basic, water is a molecule with one oxygen atom and two hydrogen atoms, bonded together by shared electrons. It is a V-shaped polar molecule, which means that it's charged positively near the hydrogen atoms and negatively near the oxygen atom. Water molecules are ...
During the electron transport chain, do electrons bond to oxygen molecules to form ions? Why are ions so important in the electron transport chain? How do root hair cells absorb water? Describe the function of organelles, cells, tissues, and the organ system as well as their role in...
The actual microscopic process that drives osmosis is a bit mysterious, but scientists describe it this way: Water molecules are is a state of constant motion, and they migrate freely throughout an unrestricted container to equalize their concentration. If you insert a barrier into the container ...
Whereas Osmosis is the process in which water crosses membranes from regions of high water concentration to areas with low water concentration. While molecules in diffusion move down a concentration gradient, molecules during osmosis both move down a concentration gradient as well as across it. Both...

Water molecules are naturally attracted and stick to each other because of this polarity, forming a hydrogen bond. This hydrogen bond is the reason behind many of water's special properties, such as the fact that it's denser in its liquid state than in its solid state (ice floats on ...
Basically, water flows through clay that contains a lot of really tiny holes, which are big enough to let water molecules though, but too small for biological contaminants, dirt, and other bad stuff [source: Doulton USA]. The first such device was developed by a British potter, Henry ...
