Continuous variables have no significance to the person experimenting, but they can influence and have an impact on the results.

  • What must cells do in order to survive?
    What must cells do in order to survive?
    A cell must be able to do all of the above to survive, simply put. In order to survive, the cell must be able to obtain and process energy. No energy, and the cell cannot do a thing. This is why the mitochondria is the powerhouse of the cell. Secondly, if a cell cannot convert the genetic information into proteins, it can’t carry anything out. Even if it has the energy, it won’t have the instructions. Without these two things, it’s like trying to put together a toy late on Christmas Eve: you’re tired and don’t want to read the instructions. Or can’t find them. Finally, if the biochemical reactions are not kept separate, a deadly reaction may occur. That’s never good.

  • Which diagram best illustrates the relationship between a phylum,order,and genus?
    Which diagram best illustrates the relationship between a phylum,order,and genus?
    The best way to put it is “phylum, order, genus”. The phylum is a larger classification. It groups organisms by a specific kind of characteristic. The order further narrows it down by characteristics. Genus is part of the bionomenclature that is used to give animals and plants their scientific names, so it defines the organism even further by a type of organism (such as “dog” or “cat”). The diagram given is also a good way to show which order it should go in. While “genus, order, phylum” could be correct reading up the diagram, “phylum, order, genus” is also correct when reading down the diagram, and therefore reading down the page. However, both orders would be correct since it shows the relationship both ways.

    How can you best define the process of osmosis?
    The answer to this is D. Osmosis is the process wherein a type of solvent will pass through a plasma membrane to an area with a high solute concentration. This can happen even when the energy is passive. It does not need movement in order to occur. One example of osmosis is the moving of the water that we place on plants. The water will go to the cell sap root hair which has a higher concentration as compared to the soil. The movement of the water particles will be precise and will occur even without putting any pressure or energy. The most common solvent that goes through osmosis is water.
