Why do cells divide? Why are B cells important? Infer why whitefish embryo cells and root-tip cells are used to study mitosis instead of cells in a human bone or plant leaf. Why do lipids make effective cell membranes in living cells?
Why do mitochondria and chloroplasts have 2 bilayer lipids around them? Do prokaryotic cells have mitochondria? If so, what is the purpose of the mitochondria? Why is the cell membrane important to homeostasis? Why do cells need carrier proteins that transport glucose?
Proteins form important structures in the body, make up a key part of the blood, help regulate many body functions, and can fuel body cells. Essential amino acids are needed in your daily diet because your body cannot make them. If you do not get essential amino acids in your diet, ...
In order to keep our bodies healthy we need to ensure we are getting the proper amount of each nutrient. Carbohydrates, our bodies main source of energy, can be absorbed through bread, pasta, beans, and vegetables. Proteins, nutrients our body uses to build and maintain its cells and ...
Although seemingly simple, these vaccines rely on a critical packaging made of lipids (fat-like molecules) to protect, and to deliver, the mRNA into cells. The packaging is composed of lipid nanoparticles. These LNPs are usually made of four types of lipids, includ...
Heart disease is a scary disease often treated with even scarier drugs—like statins! Statins (cholesterol lowering drugs) deplete the body of vital heart-nourishing nutrients and can do more harm than good! Coconut oil is full of heart-healing benefits and can help prevent the need for such ...
Given that acne commonly affects patients around the mouth, this has been interpreted as evidence of some unmet oral need. However, the potent effectiveness of isotretinoin, a retinoid that significantly reduces sebum production and is generally considered the most powerful treatment for acne but has...

Why do cells need selectively permeable membranes? What is the plasma membrane of a cell and what is the function of the plasma membrane? How is osmosis different with a semipermeable and permeable membrane? Why proteins are an excellent macromolecule for anchoring in the plasma membrane?
Why do neurons die without oxygen? Why do neurons need oxygen? Do neurons undergo cell division? How do neurons learn? Why don't neurons use lipids for energy? Why are sensory neurons structured differently in comparison to motor neurons? What are the reasons behind the different structures for...
