The statements that are true of heterogeneous mixtures are: they settle out and the proportions of solute to solvent may vary. The correct answer is option A. 1 and 2. Heterogeneous mixtures are considered mixtures wherein the components are not uniform and still retain their properties. Characteristics of heterogeneous mixtures are: the ratio of solute and solvent is not equal, the substances can be separated physically and they still retain their properties even if mixed with another substance.
B. tiny algae and plankton decomposed under conditions of heat, pressure, and low oxygen.
Explanation:
Oil is most likely to form where tiny algae and plankton decomposed under conditions of heat, pressure and low oxygen.
Coal will form when plant materials like twigs, leaves and tree trunks decomposed under conditions of heat, pressure and low oxygen.
- To form oil, algae and plankton will be gathered with sediments in a basin.
- Rapid burial causes the algae and plankton to be cut off from aerobic environment that would lead to the decay of these organisms.
- They are buried alive and as the basin subsides, temperature and pressure acts to produce kerogen.
- Further cracking produces oil and gas.

Explanation:
The way the Cell cycle works helps us keep us alive as long as usually do. An example is when you bite your cheek, you may kill some cells by it but your alive cells will replace them by creating more. Now without the cell cycle here's what would happen, You bite your cheek and your cells die forever causing your mouth to be dryer, weaker and to lack enzymes ( enzymes help brake down your food and ready it to go threw your digestive system ) So imagine every time you get hurt and your cells just keep dying without being reborn that's like as if everyone stopped creating children eventually the human race would end, If the cell cycle does not do its job eventually you will get weak and die. that's why the Cell Cycle is important to any living things well being especially if its Multicellular.

It's called merging cells. I don't understand why this is in Biology but whatever.
