Answer:
unwinding the strand.
Explanation:
The main function of DNA polymerase is to make DNA from nucleotides, the building blocks of DNA. There are several forms of DNA polymerase that play a role in DNA replication and they usually work in pairs.Polymerase move alonf the DNA unwinding the strand.
Hope this helps>.<
D) It controls materials that enter and exit the cell
The answer of that question is A I AM PRETTY SURE ABOUT IT
Hello!
In order to find the correct answer, you need to find a hypothesis that cannot be proven wrong. Out of the options in the prompt, all but one can indeed be proven wrong. The correct answer is A because there is no way anyone can tell if there is a teacup orbiting the Milky Way galaxy or not. We know that it can be proven wrong there is no life on Mars, the human species started in Africa and that humans cannot live without a certain amino acid. The only thing that really can’t be proven wrong (that is quite stupid) is the one about a teacup.
Upon studying the theory of falsifiability, I came across an example of a person who claimed they had invisible unicorns in their digestive tract. We know that this (incredibly dumb) example cannot be proven wrong because, well, there is no way to actually know what’s in someone.
Answer: The electrons in an atom that take part in chemical bonding are the electrons in the outermost shell and they are called valence electrons.
Explanation: An atom is composed of three particles: protons, neutrons and electrons. The protons and neutrons occupy the centrally located nucleus while the electrons are located in the empty space outside the nucleus. Electrons are distributed around the nucleus in paths called electron shells. The electrons in the outermost electron shells are called the valence electrons. The valence electrons are the electrons that participate in chemical bonding. During chemical bonding, the valence electrons are either transferred from one atom to another or the valence electrons are shared between two atoms. A type of chemical bonding in which there is a complete transfer of valence electrons from an atom of a metal to an atom of a non-metal so that can attain octet or duplet structure of noble gases is called electrovalent or ionic bonding. A type of chemical bonding in which there is sharing of electrons between two atoms of non-metals so that both can attain the octet or duplet structure of noble gases is called covalent bonding.
