Rico and Bree are camping and have potatoes wrapped in foil to eat. Bree put her potato in the campfire for a while, but Rico did not. Now Bree's potato has a high temperature. What is the difference between the molecules of the two potatoes? *

Answers

There is no difference because both potatoes are made of the same type of molecules.

What is Molecules?

Molecule is a group of two or more atoms that are bound together with the help of some attractive forces. These attractive forces are known as chemical bonds. It is the smallest particle of a substance that has all the physical and chemical properties of that substance.

Atoms have a single nucleus with a positive charge protons surrounded by a cloud of negatively charged electrons. When these come close to each other, the electrons interact with each other and with the nucleus, lowering the total energy of the system, then the atoms bond together to form a molecule.

There are three types of molecules:

1. Molecule of an atom

2. Molecule of an element

3. Molecule of a compound

Thus, there is no difference because both potatoes are made of the same type of molecules.

Answers

Answer:

In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The process begins when the enzyme RNA polymerase binds to a region called the promoter.

Explanation:

I took the test lol

Transcription is a particularly important stage in gene expression, since it is the main method by which the cell regulates which proteins are to be created and at what rate.

What is the role of enzyme in the transcription process?

RNA polymerase, which creates a complementary strand of RNA using a single-stranded DNA template, is the primary enzyme involved in transcription.

Each new nucleotide is added to the 3' end of the strand as RNA polymerase constructs an RNA strand in the 5' to 3' orientation.

The first step in unlocking a cell's genetic code is transcription. Enzymes known as RNA polymerases construct complementary RNA molecules to a section of one strand of the DNA double helix during transcription.

Therefore, In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The RNA polymerase enzyme binds to a region known as the promoter to start the process.

Answers

Answer:

Everything from the hawk's diet

Explanation:

Mice, rats, shrews, without their main predator, the ecosystem would become unbalanced by the increasing overpopulation of rodents and most likely small snakes that are also on hawks' diet. Another consumer would probably be other animals that eat the hawks' diet. Without a competing consumer, the, let's say snake, population would grow larger.
