Law Incorporation [45]

Answer:

The words depict the phenomenon of cell division in prokaryotes and eukaryotes.

The possible concept map that could be drawn from these words could be:

Number 1:

Cell cycle in a eukaryote occurs through the process of mitosis (or meiosis) and chromosomes duplicate by this process. Cytokinesis separates the two daughter cells by separating the cytoplasm of the two cells.

Number 2:

Cell cycle in a prokaryote involves the method of binary fission.

Which compound is a reusable, complex protein that speeds up chemical reactions?
Irina-Kira [14]
Hello there! 

The answer is enzymes. 
Enzymes are biological catalysts, which means they decrease the amount of activation energy needed to start a reaction, therefore speeding up the rate of the reaction. They are part of the protein macromolecule group. Without them, our bodies would not process things efficiently or fast enough for us to live.

Hope I helped. Have a nice day.

<span>The chemical elements</span><span> can be broadly divided into </span>metals<span>, </span>metalloids<span> and </span>nonmetals<span> according to their shared </span>physical<span> and </span>chemical properties<span>. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form </span>alloys<span> with other metals; and have at least one </span>basic oxide<span>. Metalloids are metallic-looking brittle solids that are either </span>semiconductors<span> or exist in semiconducting forms, and have </span>amphoteric<span> or weakly </span>acidic oxides<span>. Typical nonmetals have a dull, coloured or colourless appearance; are </span>brittle<span> when solid; are poor conductors of heat and electricity; and have acidic oxides. Most or some elements in each category share a range of other properties; a few elements have properties that are either anomalous given their category, or otherwise extraordinary.</span>

Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of:
SOVA2 [1]
Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents. 
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
