To capture their prey, spiders have fangs, which pierce the body wall of insects and inject venom. Spider venoms usually contain specific proteins that attack the cell membranes of the prey. The membranes and most of the contents of the insect’s body turn into a liquid that the spider then ingests for food. These specific venom proteins are most likely
ATP molecules
DNA molecules
biological catalysts
regulatory hormones

In the 1660s, Flemish physician Jan van Helmont grew a small willow tree in a pot of soil. He added only water to the pot. At the end of five years, he found that the tree had gained 75 kilograms, but there was very little change in the mass of the soil. Van Helmont concluded that the plant gained weight directly from the water. We now know that this conclusion is only partially correct because, in addition to water, photosynthesis also requires
oxygen from the atmosphere
carbon dioxide from the atmosphere
proteins from animal prey
carbohydrates from the soil
What process requires energy?
active transport
osmosis
diffusion
passive transport
