If we are talking about one single carbon atom, then 4 hydrogen atoms can be bonded to a carbon atom, because there is 4 electrons in the valence shell, and a valence shell needs 8 electrons in total, which causes the carbon to have 4 open bonds. A hydrogen has only one electron in its valence shell of 2, and needs one more to complete it. So, each hydrogen connects to 1 of 4 bonds on the carbon to complete the valence electron.
Fun fact, CH4 is methane.
Adding large amounts of salt into your body causes your cells to become hypoglycemic (net movement into the cell outweighs net movement out) and causes the cells to boost. Via negative feedback loops, your body feels thirsty to dilute the salt in your cells to return them back to normal concentrations.
I believe the answer is spring
The fruit should have a seed that's light enough to be carried by the wind. Plants like orchids, dandelions, and cottonwood are plants that have seeds that seem like they have "wings" because of the feathery bristles that they have on top of them. These seeds are lightweight and are more often carried out by the wind for pollination.
