Evolutionary trends between species are often studied in the Comparative anatomy
Such as homologous structures
Answer:
Chromosome 21 in figure D is the result of a process known as non-disjunction
Explanation:
Meiosis is the process of cell division that serves to obtain gametes, cells with exactly half the chromosome load of the species. This process involves the equal distribution of chromosomes in each daughter cell.
Non-disjunction is an alteration in the separation of the sister chromatids during meiosis, resulting in a gamete with non-separated sister chromatids, which when joined to a normal gamete can produce an organism with an extra chromosome.
In the karyotype shown in the photo, the non-disjunction in chromosome 21 produces a trisomy, a type of aneuploidy seen in Down syndrome.

The answer to the question above is the forearc basin.
Forearc basins are characterized by thick sequences of relatively underformed sedimentary rocks. Examples of the forearc basins are Banda Forearc, Luzon arc-forearc, Tohoku forearc, Central Andean forearc, Savu-Wetar forearc, and between the Western Cordillera and Peru-Chile Trench.
Answer:
Hypoxia is believed to be caused primarily by excess nutrients delivered from the Mississippi River in combination with seasonal stratification of Gulf waters. ... Stratification of fresh and saline waters prevents oxygen replenishment by mixing of oxygen-rich surface water with oxygen-depleted bottom water.
