The data table shows the percentage of amino acid
similarities found in a protein for several organisms
when compared to the same protein in rabbits.
Based on the data,which organism is most closely related to the rabbit?

How many atoms are in this picture?
Na3C6H507

Answers

Answer:

Explanation:

Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor. It is mildly basic and can be used along with citric acid to make biologically compatible buffers

Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix[clarification needed], ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine[citation needed], amongst others.

How can a material at a certain temperature have all of its molecules at the same energy?

Answers

Answer:

The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.

Explanation:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.
