Evidence of the past life preserved in rocks . This overlap of dna suggested we all derived from a common ancestor
Answer:
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.

Explanation: Fungi are multicellular and eukaryotic organisms. Its cell wall is made of a substance called chitin. It is a heterotrophic organisms i. e. take nutrients from other organisms.
Answer:
Macronutrients: water, fat, carbohydrates, protein
Micronutrients: minerals, vitamins
Explanation:
The six types of nutrients humans need are water, fat, carbohydrates, protein, minerals, and vitamins.
Macronutrients are nutrients we need in large amounts (macro- means big).
Micronutrients are nutrients we need in small amount (micro- means small).
Consider what you eat in a day, you (should) be getting all of these.
It's recommended you have about 8 cups of water a day, which is a large amount.
Fat and carbohydrates are used as sources of energy and are consumed in large amounts.
Proteins (meats, nuts) used to build muscle are also eaten in large amount.
Minerals and vitamins have recommended intakes of milligrams (mg) which is a very small amount. They are found in traces in our food. For example, you would not fill your entire palm with calcium and eat it. You only need small amounts of calcium (probably in your milk).
