Answer:
Diffusion: the Simple and the Facilitated
Diffusion is the movement of particles down their gradient. A gradient is any imbalance in concentration, and moving down a gradient just means that the particle is trying to be evenly distributed everywhere, like dropping food coloring in water. This is what happened when we made our granola - a bunch of separate ingredients came together and spread out across the whole mixture. We call this evening-out moving “downhill”, and it doesn’t require energy. The molecule most likely to be involved in simple diffusion is water - it can easily pass through cell membranes. When water undergoes simple diffusion, it is known as osmosis.
Movement Across a Membrane and Energy
There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

Answer: cancer cells given vinblastine will be unable to separate chromosomes during cell division.
Explanation:
Vinblastine is a chemotherapy medication that is use in treating different types of cancer. It is an alkaloid that is produced naturally from plants. It is mixed with other medications to treat different types of cancer. It inhibits microtubules polymerisation. It works by stopping the cancer cells from diving into two new cells,therefore blocking it's growth.

Answer:
2hydogen + 1oxygen = H2O = water
Explanation:
The answer lies with carbon's unique properties. Carbon has an exceptional ability to bind with a wide variety of other elements. Carbon atoms can form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. Carbon atoms can also form stable bonds with other carbon atoms.
