This movement occurs due to the random motion of molecules. 2. Definition of Osmosis: - Osmosis is a specific type of diffusion that refers to the movement of water molecules across a semi-permeable membrane. I
Explain the physical properties of water and how they affect the movement of water up the stem of a plant. Explain in mechanistic terms how the action potential is an all-or-none phenomenon. What situations result in motion after effect, induced movement, illusory motion of the eye, and peri...
What is the electrical nature of water molecules? explain. Describe nuclear magnetism. What is the properties of electric charge? A crystal of salt consists of electrons and positive ions. How does the net charge of the electrons compare with the net charge of ions? Explain. Explain ho...
In this model, the solid particle is considered to be surrounded by an external film offering a resistance to the mass transfer. Once the solute molecules enter into the pores of the solid particle, the model also assumes that the equilibrium adsorption is instantaneous and the adsorbed mole- ...
In a laminar flow chamber, receptor-coated microspheres move in a shear flow on top of a surface bearing ligand molecules. If a receptor binds its ligand, the microsphere stops, while a force is immediately applied to the bond. During an experiment at a given shear rate, the number of ...
Multiple fluorescence-based assays are currently available and may be used as appropriate according to the target parameter. So-called viability assays (Stocks, 2004) are applied to describe membrane integrity, based on double-staining with two DNA-intercalating fluorescent molecules (fluorophores). ...
6 Levels of Organization There are 6levelsof structuralorganization. We first begin with the chemicallevelwhich consists of atoms and molecules‚ which then combine together to form cells (the basic unit of life) this is known as the cellularleveloforganization. These cells will come toget...
"This is not the case for some materials, such as materials with very high ionic conductivity and those where the building blocks are not only atoms but also molecules. Several of the perovskites that are promising materials forsolar cellsare of this kind", Johan Klarbring, doctoral student in...
What is the difference between a spring tide and a neap tide? Why in deep waters of oceans the water seems still? Explain by using surface tension. Describe two ways a change in flux can occur. What are the differences between the convection and conduction currents? Explain wave motion. ...
A substance is known as a matter if it acquires some place (that is also known as volume) when it is placed in the space, and it has some mass also. Usually, the molecules or atoms are made with help of many tiny parts of matter. For example, Water, Ball, Pen, Pencil, Bottle, ...
