Eukaryotes
<span>Plants normally make their own food by the process of photosynthesis. Plants take in water through the roots from the ground, absorb sunlight during the day and take in carbon dioxide from the air to make their nutrients. So plants are normally autotrophic in nature. Animals on the other hand consume plants as well as other animals to produce nutrients. So animals are mostly heterotrophic in nature. Fungi release enzymes which in turn help in digesting external material. Then the fungi absorb that digested compound that is created by the enzyme. </span>
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make <u>glucose</u>, <u>acetic acid</u>, <u>amino acids</u> and <u>lipids</u>.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
The following statements apply:
1. Salt is not chemically bonded to water.
2. The ratio of salt to water may vary.
3. Salt and water retain their own chemical properties.
The solution formed by dissolving salt in water is an example of a mixture, it is a physical change and no new substance is formed. The salt and the water are not chemically bonded and salt can easily be recovered from the water by mean of evaporation. Any amount of salt can be dissolved in the water and each of the component, that is, salt and water still retain their individual chemical properties.
