Answer:
i think it's GAATTC
Explanation:
The DNA strand above is cut with a restriction enzyme at the restriction site 5’-GAATTC-3’. The enzyme makes a staggered cut between the two T’s of the restriction site is GAATTC.
What is Restriction site?An isolated bacterial protein known as a restriction enzyme cleaves DNA at sequence-specific locations to create DNA fragments with a known sequence at each end.
For several laboratory techniques, such as genetic engineering and recombinant DNA technologies, restriction enzymes are essential.
There are at least 3,000 restriction enzymes, and they are all really cool. Each of these enzymes snips a certain DNA sequence, regardless of whether the DNA comes from a mouse, a bacterium, a fungus, or a human.
Therefore, The DNA strand above is cut with a restriction enzyme at the restriction site 5’-GAATTC-3’. The enzyme makes a staggered cut between the two T’s of the restriction site is GAATTC.

Does the DNA support the hypothesis that the coelacanth is the closest living relative to amphibians, such as frogs? If it does, explain how. If it does not, provide an alternative hypothesis suggested by the DNA data.
Answer:
DNA does not support the hypothesis that coelacanth is the closest relative to amphibians.
Explanation:
After several DNA analyzes, including analysis of mitochondrial DNA sequences, scientists found that coelacanth DNA does not support the idea that it is the closest relative of amphibians. However, other molecular analyzes, looking at the DNA of other living beings, concluded that the pulmonary fish is, in fact, the closest relative of the amphibians, with Coelacanth being the closest relative of the tetrapods.

Fossils can usually be found in layers of
chronological order
radioactive dating
common ancestry
sedimentary rock
fossil record
metamorphic rock
nitrogen dating
timeline
Answer:
Sedimentary rock
Explanation:
All fossils are sedimentary rock. When an organism dies, layers of sediments pile on top of the organism, the sediments harden to become sedimentary rock. And for this reason, fossils cannot be igneous or metamorphic rock.
The diagram shows part of the digestive system. What is the function of the liquid produces in part 1 and released into part 2?
A to digest protein to amino acids
B to increase the surface area of fat droplets
C To acidify the contents of part 2
D To prevent further digestion of starch.
The liquid which the question refers to, is the pancreatic juice, which is a liquid secreted by the pancreas, which contains a variety of enzymes, including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases and amylase. These enzymes have the function of digesting proteins, fats and carbohydrates passed from the stomach into the duodenum (part 2).
So the answer is A: to digest protein to amino acidsDescribe the data used by Watson and Crick to determine the structure of DNA

13. The diagrams show steps of a cell process.
What is the name of the process shown in the diagram? (The letters are for identification but do not
indicate the order of the process.)
Answer:
It's mitosis. Notice how the daughter cells have the same number of chromosomes as the parent cell. This does not happen in meiosis where the daughter cells after the first division will have half of the starting chromosomal set
The name of the process that is shown in the diagram is known as Mitosis. This is because the daughter cell holds the exact amount of genetic content as compared to the parental cell.
What is Cell division?Cell division may be defined as a type of biological process through which a parent cell divides into two or more daughter cells. It takes place as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.
There are two types of cell division that may normally exist. They are mitosis and meiosis. Mitosis involves the formation of two daughter cells from a parental cell that contains the same amount of genetic content.
While meiosis involves the formation of four daughter cells from a parental cell that contains half the amount of genetic content as compared to the parental cell.
Therefore, mitosis is the name of the process that is shown in the diagram.
