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.
Answer:
Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents. In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
Naming ionic compounds<span> with transition metals isn't too hard either. They are</span>named<span> like the </span>binary compounds<span>, with the cation first, then the anion with -ide added to it, but you have to take into account the variations of the metal </span>ions<span>. You do this by adding Roman numerals in parenthesis to the cation.</span>
<span>The cpt codes that should be reported for this procedure are as follows: 64493-50, 64494-50. The reason for this is that these codes are for the injection of the lumbar. 64493 is the injection specifically, and 64494 is referencing L4. The -50 is added to show that the injection was done on both sides.</span>
