<span>Bt corn is a type of GMO corn which has had genes inserted into its genetic material from another organism, known as a donor organism. In this case, it is the bacterium Bacillus thuringiensis, which naturally occurs in soil. The value of the gene which has been added is that it contains a protein which kills the larvae of certain insects, especially European corn borers. This insect resistance is the chief feature of value in Bt corn.</span>

Answer:
The correct answer is :
Independent variable: study music.
Dependent variable: test performance.
Explanation:
Independent variable in a experiment is a variable or a factor that is manipulated or changed in a particular experiment to see its the effect on dependent variable of this change. In this case classical music is variable as it is manipulated to see if it has any effect on studying.
Dependent variable is a variable which is measured in experiment to find the result and affected by the independent variable. In this case testing the performance of subject is dependent variable as it is being measured and affected by classical music.
Thus, the correct answer is: Independent variable: study music.
Dependent variable: test performance.
Answer:
(B) resemble structures formed by bacterial communities that are found today in some shallow marine bays.
Explanation:
Extant stromatolites represent real "living fossils" for they are decendents of ancient forms that are associated with one of the first living forms on earth. Particularly, stromatolites are real bacteria communities where the autotrophic organism of the community are represented by cyanobacteria, which live along with heterotrophic bacteria. This clearly indicates that fossilized stromatolites points to bacteria (prokaryotes) as the first living things on earth (dated with not less than 3.5 billion year old)
Nowadays, stromatolites with cyanobacteria allows to reconstruct and understand fossilized forms. These current structures live in shallow marines ambients (e.g. Australia) but also in continental salt flats (e.g. Argentina) where few others bacteria can survive to these extreme conditions (high light exposure and salt concentration).
