What are constants or controlling variables in an experiment? What would be some constants from the experiment mentioned above?
lawyer [7]

Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

Use the drop-down menus to complete each sentence.
Svetlanka [38]

Answer:

- <u>Eukaryotes</u> are organisms that contain more than one cell with membrane-bound organelles and a nucleus.

- Organisms that contain only one cell and do not contain a nucleus or membrane-bound organelles are known as <u>prokaryotes</u>.

Explanation:

According to their structural and functional complexity, organisms can be classified into eukaryotes and prokaryotes.

  1. <em><u>Eukaryotic organisms</u></em><em> are formed by cells that have a true nucleus -where DNA is located- and specialized structures called organelles, with a system of endomembranes that compartmentalize the intracellular space. These organisms are usually pluricellular, given the ability of eukaryotic cells to group together to form tissues. </em>
  2. <em><u>Prokaryotic organisms</u></em><em> are single cells, lacking a nucleus - genetic material is scattered in the cytoplasm - and do not possess organelles.  The prokaryotic cells that form these organisms are incapable of binding together, so they do not form tissues.</em>

Some unicellular organisms are prokaryotic cells, like some parasitic microorganisms, such as amoebas.
