Answer and Explanation:
During an experiment, data from an experimental group are compared with the data of a control group. These two sets are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals. This variable keeps constant in the control group.
The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups.
In the control group, the variable measured keeps constant, not influencing the results. This isolates the effect of the independent variable on the experiment and helps to find alternative explanations to the different results.
In the exposed example:
- Control group: Certain amounts of fishes exposed to a normal number of light hours per day. For example, if under natural conditions in its original environment the species is exposed to 12 hour light, then the control group should be exposed constantly to 12 hours light a day to maintain its normal reproductive levels.
- Experimental group: Certain amounts of fishes, equal to the control group, exposed to a different number of light hours per day. For example, there might be 5 experimental groups: one of them exposed to 4 hours light, a second group exposed to 8 hours light, the third group exposed to 12 hours light (The same as the control group), the fourth group exposed to 16 hours light, and the fifth group exposed to 20 hours light.
Except for light, the rest of the variables should be the same for all the groups.
Well, to know the answer to this question, you must know the meaning of vertebrae. Vertebrae are just a connections of bones that make up your backbone. These include about 24 ligaments that make up your spine. So all vertebrae are bones since they are ligaments and other bones that make up, well, your backbone! However, not all bones are vertebrae, because your finger bones, ribs, skull, and other bones in your body aren't part of your backbone.
Hope this helps!

Answer: Lydell Grant, acknowledging that he was wrongfully convicted of murder has only meant purgatory, nearly seven months of it. He is neither free nor behind bars, nor can he restart his life. The laggardly movement of his case for exoneration, which his supporters say only underscores the frustrations and larger belief that systemic racism is ingrained in the justice system, has left him in a different type of cage. A jury convicted Grant of the 2010 fatal stabbing of a man outside a Houston bar, sending him away for life. Grant spent his days in prison reading about the legal system and writing letters to whoever he thought would take up his cause. Then, in 2019, with the help of a legal team with the Innocence Project of Texas and forensic scientists who used emerging DNA technology, new evidence was collected that convinced Harris County District Attorney Kim Ogg to support a request for bond.Grant was released from a Texas prison just before Thanksgiving Day.In December, prosecutors confirmed that re-examined DNA recovered from the fingernails of the victim, Aaron Scheerhoorn, had yielded charges against a new suspect found through an FBI criminal database. Houston Police Chief Art Acevedo said Jermarico Carter of Atlanta, who had a criminal record, confessed to having stabbed Scheerhoorn and was arrested. Acevedo personally, and publicly, apologized to Grant.
