<span>Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span>
Mitosis is the division that results in two “daughter” cells. Both of these daughter cells have the same number of chromosomes as the “parent” cell.
Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase.
Prophase: the DNA is copied and the chromosomes pair up
Metaphase: the chromosomes line up in the middle of the cell
Anaphase: sister chromatids are pulled apart from each other towards opposite sides of the cell
Telophase: the cell begins to pinch in the middle and separates into two identical daughter cells
<span>B. Rocks go through many stages during their formation</span><span>
Sedimentary rocks together with the igneous rocks and the metamorphic rocks are the three main types of rocks that existed on earth. It is formed or made accordingly into four major ways. First, it is formed by depositing weathered remains of "clastic sedimentary rocks" or other rocks. Second, is through accumulation and the consolidation of sediments, thirdly is by depositing the results of biogenic activity and lastly it is formed through precipitation from solution. Limestone, shale, chalk clay and others are best examples of sedimentary rocks. </span>
From the data, the manatee population obviously increased after the regulations went into affect and the deaths due to watercraft reduced from 25 to 8 after the regulations were put into effect. The population increased by 165% from 1980=-2010 and the drop in deaths due to watercraft decreased by
68%.So this is not a direct correlation but at least it shows that the watercraft deaths decreased significantly. Since the population increased at a greater rate then it may be that more females were spared so could mate and give birth to that many more manatees.
