Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

Answer:
See the answer below
Explanation:
A human and a cat with XXY chromosome share two things in common mainly:
- <em>They are both males</em>
- <em>They both suffer from Klinefelter syndrome</em>
In humans and cats, sex is determined by the XY chromosome system. The male sex chromosome is XY while the female sex chromosome is XX. Male individuals with an extra chromosome are XXY and usually suffer from a chromosome disorder known as the Klinefelter syndrome.
The Klinefelter syndrome in humans is characterized by small undescended testes, gynecomastia, and unusually small penis due to the shortage of the testosterone hormone.
Well, many people might associate this to the increase in the movement of particles that occurs along with the increase in temperature, but that might not be enought to move ocean water to different places.
I'd relate it to density. Because, the higher the movement of particles, the lover the density. Which means that if we start cooling and sinking bringing new water to the surface, and if that becomes a cycle, along with water currents, we can create a movement.
↑ In my opinion, that is a really good point, so you should elaborate more on how the water currents will affect the process, and that should be it.

Answer:
Both molecular and morphological comparisons among dugongs and proboscideans species should be conducted
Explanation:
From a molecular biology point of view, it is possible to compare the sequences of dugongs and proboscideans and thus observe the homology level between genes of interest, it in order to establish evolutionary relationships among species. Moroever, by mass spectrometry (MS), it is possible to compare proteins in fossils >1 million years, these comparisons may shed light on the evolutionary origin of one group
