Organisms are classified into one of three domains by scientists. Which of the following characteristics is used most often to classify organisms into the proper domain?

A. genetic similarities
B. body shape similarities
C. presence or absence of photosynthesis
D. presence or absence of a cell membrane

Answers

Answer 1

Answer:

Most likely A. Genetic similarities

Explanation:

Because that is how you can tell they are alike and what they have in common to actually classify what family, kingdom, and domain they are in.

Answer 2

Genetic similarities are used most often to classify organisms into the three domains. Therefore, the correct option is A.

What are the three domains of life?

The three domains of life are Bacteria, Archaea, and Eukarya, and they are distinguished based on their genetic differences. For example, Bacteria and Archaea are prokaryotes and lack a nucleus, while Eukarya are eukaryotes and have a nucleus.

The genetic material in Bacteria and Archaea is organized differently from that in Eukarya, and they also have distinct cellular structures and metabolic pathways. Therefore, genetic differences are the primary characteristic used to classify organisms into their appropriate domain. Therefore, the correct option is A.

The process by which green plants and some other organisms use sunshine to create meals from carbon dioxide and water is called photosynthesis. Therefore, option (A) is correct.

What is photosynthesis?

Photosynthesis is the process by which green plants and some other species use sunlight to create food from carbon dioxide and water. Other organisms may also participate in this process. Chlorophyll, a green pigment, is typically involved in the process of photosynthesis, which results in the production of oxygen as a byproduct in plants.

Photosynthesis takes place in the chloroplast, a specialized intracellular organelle found in plants and algae, which emerged considerably later. During the day, photosynthesis is carried out by chloroplasts. The photosynthetic cells use NADPH and ATP, the direct results of photosynthesis, to make a variety of chemical compounds.

A Eastern mole, coyote, and red fox, because they all have thick fur.

B Coyote, eastern mole, and red fox, because they live in similar habitats.

C Eastern mole and side-striped jackal, because they have specified dietary needs.

D Side-striped jackal, red fox, and coyote, because they have shared physical characteristics.

Answers

Answer:

Kingdom Animalia

Explanation:

Living organisms have been classified into a large group called DOMAIN. Based on the domain classification, living organisms are either prokaryotic (without a membrane-bound nucleus) or eukaryotic (possess membrane-bound nucleus). The domains were further classified into six (6) Kingdoms viz: Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.

Each living organisms that make up a Kingdom has its own characteristics. Based on the characteristics outlined in the attached image, it depicts that of a living organism in Kingdom Animalia because all animals are belong to the domain Eukarya i.e. are eukaryotic, multicellular and heterotrophic.

Organisms in Kingdom Animalia depend on other organisms for their food source i.e. heterotrophic. They possess more than one cell i.e. multicellular.
