Answer: Stratigraphy and Biostratigraphy
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.

B is the only answer that correctly correlates to the question. Heterotrophs are organism that are not able to produce their own source of food. To acquire food, they depend on the organic molecules produced by producers.
A decrease in the overall volume of gases like hydrogen can prevent nuclear fusion in a nebula.
Explanation:
Nuclear fusion: The reaction of combining two or more atomic nuclei to form one or more different atomic nuclei and subatomic particles is known as nuclear fusion. A single heavy nucleus is formed from two lighter nuclei. Helium is made by fusing Hydrogen atoms together.
Nebula: A nebula is a giant cloud dust and gas in space. Nebulae are formed out of the gas and dust that are thrown out by the explosion of a dying star.
A decrease in the overall volume of gases like hydrogen can prevent nuclear fusion in a nebula.
Answer:
GTACCGA
Explanation:
During DNA replication, the purine bases adenine and guanine binds to the pyrimidine bases thymine and cytosine respectively.
From the above original strand, the complementary strand will be:
GTACCGA
