its internal volume (cubic function) grows faster than its surface area (square function). This places a limit on the organism's size, because substances from the outside of the organism must pass into and throughout the organism by diffusion, which depends upon large surface...
Osmosis is the passage or diffusion of water or other solvents through a semipermeable membrane that blocks the passage of dissolved solutes [source: Encyclopedia Britannica]. What, you don't get it? No fear. Most of us don't, which is why there are countless explanations and analogies to ...
How does a cell's organelles help carry out the 6 characteristics of life? How is cell differentiation different in plants and animals? Why simple diffusion is enough for performing various life processes in unicellular organisms and why not in multicellular organisms?
The GNoME database probably includes interesting compounds, say its DeepMind scientific creators. But they acknowledge it’s only a preliminary step in showing how AI could help in materials discovery. Much work remains to broaden its usefulness. Ekin Dogus Cubuk, a Google research scientist and co...
In 2022, we've seen the advent of some incredible text-to-image generators. The first to set off the big wave was Dall-E 2, with Stable Diffusion arriving a short while later. Since then, we've seen other tools arrive too, including Midjourney, Craiyon, and even TikTok to a certain...
. It is used in some hydroponic vegetable (and other plant) production systems. The large pore spaces it creates and the wicking action it does in the container helps keep a balance of air and water for the roots. The #1 leading cause of death among houseplants is overwatering – it ...
Dall-E 3, whose name is a mashup of Pixar's WALL-E robot and surrealist painter Salvador Dalí, isn't the only text-to-image generator promising to produce your next masterpiece in seconds.Popular tools in this categoryincludeMidjourney,Stable Diffusion,Shutterstock's AI image generator,Canva...
How does homeostasis affect the body? How does diffusion help maintain homeostasis? How does the respiratory system help maintain homeostasis? How do we know if homeostasis was achieved? How does the lymphatic system help maintain homeostasis? How do stomata help plants maintain homeostasis? How does...
The temporal scope of our study does not capture the full pandemic as it is still ongoing at the time of writing but it includes the three major contagion waves in the U.S., characterizing the entire year of 2020. The first wave captured the initial diffusion of the virus in the world,...
This is called the diffusion theory.How do Post-it® notes work?So what about that little Post-it® note stuck to your wall? How does that work?Look at the back of a sticky note using an electron microscope and you'll see not a continuous film of adhesive but lots of microscopic ...
