Two organisms have analogous structures. A student concluded that these organisms must have a common ancestor is the student cor
arsen [322]

Answer:

The student is wrong, just because the analogous structures of any two organism may have the same structure or even have the some relation between there way of operation or functions.

Explanation:

  • <u>Analogous Structures:</u>

As the similarity between two or more different organisms structure or any organ does not means that they have same ancestors or have the common origin from which the evolve into two different species. Now analogous structures are very much similar in there structure physically, but two different organisms may use them for the same function, which is astonishing to see or observe in way different species.

  • <u>For example:</u>

As the structure of the flipper of a Dolphin has similarity with the phalanges of a human being and with the wings of the bat. As all of them functions for the basic need of movement or locomotion from one point to another. While, all the three species are very much different in there features and are not the same obviously.

Which of the following statements is true?
mafiozo [28]

Answer:

The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.

Explanation:

The kidneys are the organs that control, for example, <u>the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. </u>These organs are also key to <u>eliminate the toxins from the body. </u>

The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.

The kidneys <u>do not regulate blood glucose</u>. That is the job of the pancreas through two hormones called insulin and glucagon.

The kidneys <u>do not remove nitrogenous wastes</u> (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.
