Answer:
B) meteorite sample
Explanation:
The age of the solar system, derived from the study of meteorites (thought to be the oldest accessible material around) is near 5 billion years; that of the Earth is taken as 4.6 billion years. The oldest rocks on Earth are dated as 3.8 billion years.
Answer:
The steps will be in order in the sequence 12,13,11,4 and 15
Explanation:
12. In glycolysis, glucose is converted into pyruvate. ATP and NADH ARE MADE.
13. Pyruvate is oxidized and converted into acetyl CoA in the mitochondria. Carbon dioxide and NADH are also made.
11. The acetyl CoA undergoes a series of changes and ATP, FADH2, NADH, and carbon dioxide are released.
4. NADH and FADH2 lose their electrons and get converted back into NAD+ and FAD.
15. Oxygen takes electrons and water is produced. 34 ATP molecules are released.
Answer:
The rocks may have different textures
Explanation:
If we have to igneous rocks, and they have the same minerals, that doesn't necessarily means that they will have the same name, thus being classified as the same rock. The reason for this is that the two igneous rocks may have a different texture. One of the rocks may have a foliated, while the other may have porphyritic, giving them different appearance despite the same minerals being in both of them. The reason why two igneous rocks with the same minerlas may appear different, is the process in which they have been formed, the quickness of the cooling, the temperature that they were exposed to, and the pressure they were exposed to.
