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.

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
kolbaska11 [484]

Answer:

True

Explanation:

<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>

<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

Korolek [52]
Volcanoes, earthquakes and mountain ranges are all results of the tectonic movement of the Earth. 
<span>When two plates collide and one does not completely give way and go under the other the crust is pushed up forming mountain ranges. 
</span>An earthquake is the shaking and vibration of the Earth's crust due to movement<span> of the Earth's </span>plates<span> (plate </span>tectonics<span>).
</span>And volcano is created <span>when </span>plates<span> are pushed together or pulled apart.
So, the relationship between volcanoes, earthquakes and mountain ranges is their connection with the tectonic movement of the Earth.</span>
