Hemoglobin is found in the red blood cells and are responsible for binding onto oxygen molecules. By binding to the oxygen, it can transport it to through out the body where it is needed.
Answer:
The red balls here refers to the hydrogen and black balls refers to carbon.
The four bases in DNA are: adenine, thymine, cytosine, guanine.
In RNA, thymine gets replaced by uracil.
Purine is only a name for the two bases guanine and adenine.
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.
Sediment - rock that has formed from sediment deposited by water or air
Deposition - the geological process in which sediments, soil and rocks are added to a landform or land mass
Environment - the surroundings or conditions in which a person, animal, or plant lives or operates
