that is true it is made up of different forms of life
Answer:
c) 3
Explanation:
Cellular respiration includes following 3 processes:
1) Glycolysis
2) Citric acid cycle or TCA or Kreb's cycle
3) Electron Transport Chain (ETC)
In glycolysis, a 3 carbon compound known as pyruvate is produced from glucose. Each glucose molecule produces 2 pyruvate molecules. Each pyruvate molecule then enters a complex known as Pyruvate dehydrogenase complex wherein the pyruvate molecule further undergoes oxidative decarboxylation to produce a 2 carbon compound known as Acetyl-CoA.
.
The Acetyl-CoA then enters citric acid cycle or TCA or Kreb's cycle wherein this Acetyl-CoA and oxaloacetate are oxidized to produce CO₂ molecules in eight steps. Each glucose molecule is capable of producing six CO₂ after the completion of citric acid cycle. Since one glucose molecule produces 2 pyruvate molecules then it means <u>a pyruvate molecule will be able to produce three CO₂.</u>
The Hubble Space Telescope is a large telescope that was launched by NASA in 1990. It is named after the astronomer Edwin Hubble.
Limestone deposits can help researchers learn about what the area was like thousands of years ago as Limestone can contain fossilized plants and animals.
Explanation:
- Limestone often contains fossils of shelled sea creatures. Entire reef formations and communities of organisms are found preserved in limestone.
- The types of fossils found in limestone include coral, algae, clams, brachiopods, bryozoa and crinoids.
- Limestone is a sedimentary rock made almost entirely of fossils.
- Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.
- Limestone is composed of the mineral calcite; calcium carbonate. It often has variable amounts of silica in it, as well as varying amounts of clay, silt, and sand. Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite.
