Why is active transport important to organisms? Why does active transport require energy input by the cell? Why is it important that cell membranes are semipermeable? Why is diffusion important to cells? What facilitates passive transport ac...
Why are enzymes important? Why is diffusion important to cells? Why is it important that cell membranes are semipermeable? What are the main functions of the smooth endoplasmic reticulum? Why do mitochondria and chloroplasts have 2 bilayer lipids around them?
What is the function of the papillary muscles and chordae tendineae? (a) Where do the interneurons branch off to? (b) What are their functions in the spinal cord? How do the vasa recta promote countercurrent exchange? Why does diffusion of gases constrict and dilate? The Purkinje fibe...

Homeostasis is a word that is used to describe/denote the balancing within a system. Note that this term is so often associated with organism physiology, as the body, as well as the cell, is a perfect example of a system that relies on homeostasis to function and live. ...
Most animals are complex multicellular organisms that require a mechanism for transporting nutrients throughout their bodies and removing waste products. The circulatory system has evolved over time from simple diffusion through cells in the early evolution of animals to a complex network of blood ve...
Why Dissolved Oxygen is Important Dissolved oxygen The dissolved oxygen (DO) isoxygenthat is dissolved in water. The oxygen dissolves by diffusion from the surrounding air; aeration of water that has tumbled over falls and rapids; and as a waste product of photosynthesis. An simplified formula is...
This transport produces movement of particles and/or heat that can be used by organisms to harvest energy. Each gradient can generate different kind of forces and processes (mechanical-movement of water masses, diffusion, thermal fluxes, chemicals, etc.) expressed at different scales. The total ...
Why is maintaining homeostasis particularly important to single-celled organisms? Which describes the role of oxygen in photosynthesis and cellular respiration? Why is diffusion important to cells? For what purpose does a cell use the energy from redox reactions in cellular respiration?
Why are enzymes important to cells? Why is cell division so important? Why is diffusion important to cells? Why is cell differentiation important in multicellular organisms? How do B cells depend on T cells? Why it is beneficial for cells to be small?
