Which of these would most likely result in a change to the current classification of an organism?

Answers

Hello. This question is incomplete. The full question is:

"Which of these would most likely result in a change to the current classiﬁcation of an organism? A- Discovering organisms with similar physical traits in the fossil record B- Finding a related organism that was previously considered extinct C- Linking the organism to different ancestors through DNA sequencing D- Observing organisms that occupy the same ecological niche. "

Answer:

C- Linking the organism to different ancestors through DNA sequencing

Explanation:

To formulate the oldest classifications, ecological and physiological characteristics were used, as well as all others that are available for the taxa in question. However, in recent years, classifications based on the similarity between genomes have been attempted, with great advances in some areas, especially when those from other fields of Biology are added to this information. Because of this evolution in the classification technology, a change in the current classification of an organism could occur by linking the organism to different ancestors through DNA sequencing.

The classification of living beings is part of the systematic, science that studies the relationships between organisms, and which includes the collection, preservation and study of specimens, and the analysis of data from various areas of biological research.

Which of these would most likely result in a change to the current classification of an organism?

An analysis of the DNA sequence of an organism will most probably result in a change to a current classification of an organism.
>>>DNA analysis is one of the new reasons why organisms/species are being re-evaluated . Basic genetic analysis information can change our ideas of how closely two organisms/species are closely related thus, their classification can change.

What two properties of water contribute to capillary action?

Answers

Answer:

Adhesion and cohesion

Explanation:

Capillary action refers to the ability of water to move in small-diameter or narrow tubes against the force of gravity. Water has a tendency to form hydrogen bonds with other water molecules.

Intermolecular hydrogen bonding allows the water molecules to stick together. This tendency of water molecules to stick together is called cohesion. Adhesion is the ability of the water to stick to other substances with polar or charged groups. As a consequence of cohesive and adhesive properties, water exhibits capillary action. When water moves through microscopic spaces present between the soil particles towards the roots, it is capillary action.

Which sugar is present in the nucleic acid that is represented in the diagram?

Answers

In order to determine the sugar molecule associated with the nucleic acid, we must first determine if the nucleic acid is a deoxyribose nucleic acid (DNA) molecule or a ribonucleic acid (RNA) molecule. We can determine this by looking at the bases in the molecule, as DNA has thymine and RNA has uracil. After the type of molecule is determined, the nature of the sugar is given by the name. DNA has deoxyribose and RNA has ribose

If the asthenosphere cooled and stopped flowing. How would you expect the movement of tectonic plates in the lithosphere to change? The tectonic plates would _________?

Answers

If the asthenosphere cooled and stopped flowing. The movement of tectonic plates in the lithosphere changes. The tectonic plateswould move less than 2 cm a year.
