Answer:
Lightyears
Explanation:
When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.
Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.
This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km
If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.

A student combined baking soda and vinegar. Is this an example of a chemical reaction? Use evidence and scientific reasoning to support your claim.
Answer:
It is not a chemical reaction, because you can still separate it, meaning it is a physical change. Also it did not make a new substance, burn, or rot also making a physical change.

During DNA replication what occurs
Answer:
What happens during DNA replication?
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

What happens next after the ribosome reaches the start codon?
A. Peptide bonds between amino acids are broken.
O B. The ribosome detaches from the amino acids.
C. TRNA molecules attach to codons.
D. The ribosome finds the stop codon.
Once the ribosome reaches the start codon, the next step in protein synthesis is the binding of a complementary tRNA molecule carrying the appropriate amino acid to the codon, which is option C.
What is translation in proteins?During translation, the ribosome reads the codons in the mRNA strand, which specify the sequence of amino acids that will be assembled into a protein. The ribosome does this by binding to the mRNA at the start codon (usually AUG), which indicates the beginning of the protein-coding sequence. Once the ribosome is positioned at the start codon, the first tRNA molecule carrying the appropriate amino acid binds to the codon via complementary base pairing between the codon and the anticodon of the tRNA.
Hence, the next step in protein synthesis is the binding of a complementary tRNA molecule carrying the appropriate amino acid to the codon, which is option C.

Dr. Bailey and his team are studying two plates that are far apart from each other.
However, these two plates used to be next to each other. Which diagram shows
what Dr. Bailey and his team would find between these plates?
Answer: Diagram A: Soft, solid rock from underneath the plates rose and hardened adding solid rock to the edges of both plates.
Explanation:
Sand makes up the top layer of the Earth's crust under the ocean. The outer layer of the Earth is composed of solid, hard rock, beneath both the soil and the water. Thus, option A is correct.
What solid rock from underneath the plates?Underneath the sand and gravel on the surface is a solid, hard rock known as the bedrock. Bedrock also provides stability for the sand and other sediments that make up the ocean floor.
The rigid, stony, outermost layer of the Earth is referred to as the crust. It is composed of low-density, easily melted rocks; the continental crust is mostly composed of granitic rock, while the oceanic crust is primarily composed of basalt and gabbro (see granite).
Therefore, Soft, solid rock from underneath the plates rose and hardened adding solid rock to the edges of both plates.

Answer and explanation:
No, because most people are infected with salmonella by eating foods that have been contaminated by the s-word. Since our society is much more industrialized, we are cleaner when it comes to making food. Salmonella is mostly found in dirtier countries such as third world countries. Obviously, other food-borne illnesses are out there, but salmonella is not as common anymore, since we are improving.
