the technique of calorymetry is used to determine the energy content of food items.
The diffusion of water through a cell membrane to reach dynamic equilibrium.
Answer:
Concentration gradient means difference in solute concentration among two regions of a solution.
Explanation:
When there is a difference in solute concentration in the two regions of a solution then the term concentration gradient is used .
Various membrane transport process such as passive transport(diffusion and osmosis),facilitate transport depends on concentration gradient of solute molecule in both sides of plasma membrane.
During passive and facilitate diffusion solute molecules are transported along their concentration gradient that means from high concentration region to the region of low concentration until equilibrium is being established.
Answer:
Sponges, the members of the phylum Porifera, are a basal animal clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells
