Answer:
The correct answer is option C. "Uncovered meat that had contact with air".
Explanation:
In 1668, the Italian scientist Francesco Redi performed a celebrated experiment to prove that maggots are not spontaneously created by placing fresh meat in each of two different jars: one opened and one covered with a cloth. Redi used an uncovered meat that had contact with air as a control, expecting that flies will come in and the maggots will be developed as they do in nature.

Answer:
RFLP analysis.
Explanation:
RFLP (Restriction fragment length polymorphism ) may be defined as a molecular technique used to determine the location of a particular gene in the DNA sequences. The individuals among the population can be easily identified by RFLP analysis.
The restriction enzyme is used for the digestion of DNA sample. The restriction fragments are then visualized by running the fragments on gel electrophoresis. The hybridization between single stranded nucleic acid is not involved in the RFLP.
Thus, the correct answer is option (1).
Answer:
Frogs with deformities that typically include missing limbs, extra limbs, partial limbs, limbs that are bent and contorted, or limbs that have little muscle, are malformed frogs. Most frogs are usually malformed because of the sensitivity to the environmental factors around them while growing out of the tadpole stage
Answer:
The law of superposition
Explanation:
The law of superposition is an axiom and a basic principle of sedimentary stratigraphy, it explains that the layers of sediment are deposited in a temporal sequence, in which the oldest are in a lower position than the most recent. Therefore, if there has been no deformation, the lower layers were deposited before the ones above, so they are older.
