To sort the rock layers by age, you can use the principles of relative dating and correlation, such as the law of superposition and the principle of original horizontality.
After cutting out the drawings of the rock layers, you can begin the process of sorting the layers by age by using the principles of relative dating and correlation. The first principle is the law of superposition, which states that the oldest rock layer is at the bottom and the youngest is at the top. The second principle is the principle of original horizontality, which states that layers of sediment are originally deposited horizontally. By examining the characteristics and relationships between the rock layers, you can determine their relative ages.

B. tRNAs are bringing amino acids to the ribosomes.
C. mRNA is still in the nucleus.
D. rRNAs expose their anticodons.
The answer is B
Before the process of translation occurs, mRNA which bears the blue print or coded information for the synthesis of a specific protein arrives from the nucleus and into the cytoplasm where there are ribosomes
mRNA then attaches itself to a ribosome. The ribosome is the site where the protein is formed. It is sometimes referred to as the "work bench" of the cell. Once mRNA is attached, tRNA comes and begins to read and translate the coded information on the mRNA. This is the translation stage of protein synthesis.
Based on the translated information, tRNA then fetches amino acids from the pool of free amino acids found in the cytoplasm and brings them to the ribosome where they are joined to form a chain thus creating a protein.
All of the following such as DNA sequencing, PCR, electrophoresis, and DNA hybridization are used in molecular techniques for genetic analysis.
Genetic analysis is the science of identifying, studying, and diagnosing genetic variations in an organism's DNA. The most common molecular techniques used in genetic analysis include DNA sequencing, PCR, electrophoresis, and DNA hybridization.
All of these techniques share the underlying theme of genetic analysis, with a focus on the analysis of genetic variations in DNA. DNA sequencing is used to read and interpret the genetic code, while PCR is used to amplify specific DNA sequences, enabling their detection.
Electrophoresis is a technique that separates DNA fragments based on their size, charge, and other physical properties, and DNA hybridization is a technique that detects and quantifies specific DNA sequences by binding them to complementary DNA probes.

Your question is incomplete, most probably the complete question is:
What underlying theme do the four molecular techniques share?
A. DNA sequencing
B. PCR
C. electrophoresis
D. DNA hybridization
B) enclosed in protein capsule
C) undergo cellular respiration
D) produce proteins in ribosome
Answer:
The correct answer would be B) enclosed in a protein capsule
Almost all living cells contain DNA as their genetic material. DNA control and coordinates the function of the cell. The two cells also must contain the DNA.
Cellular respiration refers to the set of biochemical reactions by which the cell generates ATP or energy. All the living cells produce energy through cellular respiration, however, they may utilize the aerobic or anaerobic form of respiration.
A ribosome is found in all the living cells including animal cells, plants, bacteria et cetera. They form the site for protein synthesis in all the cells.
The protein capsule is not a universal feature of all living cells. Thus, it may be present in one cell type and absent in another cell type.
Answer:
The answer is B) Enclosed in protein capsule.
Explanation:
If you look at all the other options, they are present in all the cell types. Be it a plant cell or an animal cell or bacterial cell, they all contain the genetic material DNA, they undergo or exhibit cellular respiration which is responsible for the release of energy and all the cell types contain ribosomes which is the site of protein synthesis. Only some cell types are enclosed by protein capsule like some viruses but not all cell types, thus the answer is B.
