Answer:
Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.
Explanation:}
The provide direct energy because they help it grow plants and when plants grow it helps us live.
But it also provides indirect energy because the sun can cause droughts which is bad because with droughts we dont have enough water to water the plants and with that they dry out and die.
Explanation:
under what circumstance does a negative cell presents An antigen to another negative cell
Answer:
The problem: Under Martian gravity, the soil can hold more water than on Earth, and water and nutrients within the soil would drain away more slowly. Some conditions would make it difficult for plants to grow on Mars. For example, Mars's extremely cold temperatures make life difficult to sustain.
Scientists have conducted plant experiments simulating Martian conditions using volcanic soil in Hawaii, which is known for its similarity to Martian soil. These experiments found that plants can actually grow in these soils.
There are other aspects future Mars explorers will need to consider when growing plants on that planet. As mentioned earlier, Mars’s atmosphere is mostly carbon dioxide, and plants need this gas just as much as we need oxygen to breathe.
