do rocks and twigs contain water?
twigs usually have water. Its possible to dry them out.\n\nRocks can be porous enough to trap water inside them.
im studying the digestive system right now, so i'll have a go at this question (u may want to chec accuracy).\nthe cell gets the carbon it needs via the blood supply. when we eat, all the nutrients are broken down and molecules such as hydrogen, oxygen and carbon are filtered into the blood stream so that they can be passed on to all the cells in th body.\n\ndoes that help?
