Answer:
Sight, hearing, smell, taste, and touch
Explanation:
The correct answer is protons and electrons.
Atoms are made of particles called protons (p+), neutrons (n0), and electrons (e-).
Protons and neutrons are located in the center of the atom, making up the nucleus and electrons surround the nucleus.
The charge on the proton and electron are exactly the same size but opposite and their number in the atom is the same when we talk about neutral atoms. Ions are charged atoms, so the number of their electrons and protons are different (for example, positive ions have more protons).
Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
The number of H+ ions moving down the channel.
So id say the answer is C.
She didn’t cycle the reaction! She has to cycle as follows:
1. 95C-to denature the double stranded DNA
2. 50-55C depends on her primers- to anneal the primers to the single stranded DNA
3. 37-42C depending on the enzyme used - DNA polymerase extends from the primers to make the new DNA.
Also, are the dNTPs special? Either radioactive or with a fluorescence to measure/detect them?
