Sandstone is made of sand-sized particles. Siltstone is made of smaller particles. Silt is smaller than sand but larger than clay. Shale has the smallest grain size. Shale is made mostly of clay-sized particles and hardened mud. Choices: - particle depth - density - color - size of sediment A:
size of sediment

Q: Q: What molecule can be used by the body to synthesize cholesterol ? Read this paragraph and choose the correct option from the provided answers: Because of the link between high levels of cholesterol and heart disease, it is commonly seen by the general public as a "bad" molecule. However, cholesterol plays a vital role in the body, as both a structural component of cell membranes and a metabolic precursor to various steroid hormones. Only about 30% of the cholesterol in our bodies comes from our diet; the rest is synthesized in the liver, intestines, adrenal glands, and reproductive organs. The same acetyl CoA molecule that provides biochemical energy can also be used by the body to synthesize cholesterol. There are approximately twenty-two steps involved in the formation of cholesterol from acetyl CoA. Choices: - ethylene coa - hydroxide coa - chloride coa - acetyl coa A:
A: acetyl coa
