Explanation:
The cell was first discovered by Robert Hooke in 1665 through the microscope. Theodor Schwann and Matthias Jakob Schleiden discovered cell theory and postulated that All living organisms are composed of one or more cells
,the cell is the most basic unit of life and All cells arise only from pre-existing cells
Answer: Upwelling brings nutrient-rich deep waters to the surface, where algae can thrive in the sunlight, feeding the fish. ... The strong dependency of upwelling processes on the strength of trade winds contains one hint. Remember that trade winds are zonal winds, which feed off the latitudinal temperature gradient.

Answer:
<em>A: Tetrads do not form in prophase II</em>
Explanation:
Prophase I and prophase II are stages in meiosis which is the division of sex cells that results in the production of haploid gametes or daughter cells.
Meiosis involves two successive division. At the end of the first division, two daughter cells are produced while each of the produced daughter cells undergo another division each to give four daughter cells at the end.
Meiosis I involves prophase I, metaphase I, anaphase I, and telophase I while meiosis II involves prophase II, metaphase II, anaphase II, and telophase II respectively.
Prophase I marks the beginning of meiosis and it involves a synapsis of homologous chromosomes to form a 4-chromatids structure known as bivalents or tetrads. On the other hand, prophase II does not involve formation of tetrads, rather, it involves the dissolution of nuclear envelope and formation of spindle. The chromosomes at this stage are not in 4-chromatids but 2 chromatids each.
<em>The correction option is A.</em>
The answer should be B, since eukarya and archaea are in the bacterial family
