You are on vacation and see an organism that you do not recognize. discuss what possible steps you can take to classify it.
bija089 [108]

Taxonomy is the branch of Science, in which we study the Classification of Organisms. On discovering an unknown organism, begin classification by looking for anatomical features that appear to have the same function as those found on other species.

In order to correctly classify an organism, scientists use many modern tools.

1.Morphology describes the physical characteristics of an organism. Typically, this is enough information to place the organism within a domain and kingdom.

2.DNA and biochemical analysis allow scientists to test less visible, but distinguishing, characteristics.

3.Comparing embryology allows scientists to group organisms that share common fetal development.

<span>4.Evolutionary phylogeny describes the evolutionary relationships between organisms.</span>These relationships are deduced based on shared traits that may have been passed from ancestor to new species. Traits may include physical traits (ex. presence of jaws), or may be genetic traits (shared genes).

Sketch and label a food-web that includes at least 6 different items. Make
astra-53 [7]

Answer and Explanation:

Example of a food-web:

(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.

1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.

The next links are the consumers:

2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.

3) Krills are the secondary consumers and feed on protozoans.

4) Some species of cephalopods feed on krill, among other species.

5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.

6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.

Compare and contrast the processes that form different fossil types
marishachu [46]
<h3><u>Processes that form different fossil types:</u></h3>
  • The remained parts and elements of an organism that live several years ago is called as fossils.
  • Due to natural processes like weathering, soil erosion and other geological activities fossils are hard to preserve.
  • Carbonization, permineralization, recrystallization and replacement are the fossil formation processes.
  • Carbonization is the chemical reaction forming the thin film of carbon of the organic material.
  • Permineralization includes the fossils of bones and teeth. The recrystallization process is responsible for changing the micro-structure of the organic materials to form the fossils.
