Answer:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA.
EXPLANATION: SO THE CORRECT ANSWER IS
"NUCLEIC ACID"
The neuron maintains a resting membrane potential. ... Because potassium is in high concentration inside the neuron, there is a concentration gradient attempting to force potassium out of the cell. Similar forces will attempt to move sodium ions into the neuron. so the answer is A ions
Answer:
A difference of 1 would mean there is either x10 more or less depending on where you are starting.
Explanation:
The pH of 3 differs from 4 because the acidity of 3 is 10x higher than that of 4. This is due to how the scientific notation of 3 in relation to pH is 10x^-3 while that of 4 is 10^-4 so in terms of the stronger acid that would be the one with the pH of 3.
(6.0×10^4) = 60,000
(3.1×10^-1) = 0.31
60,000 × 0.31 = 18,600
Answer:
1. Nonmetal
2. Nonmetal
3. Covalent
Explanation:
Methane is the molecule being described in this question. It has a chemical formula of CH4 where four hydrogen atoms are bonded to one central carbon atom. Carbon as well as hydrogen are non-metallic elements, which means that they can only share their valence electrons to form a COVALENT BOND.
A covalent bond is a type of chemical bond in which two atoms share their valence electrons. It occurs between two non-metallic atoms. In this molecule, CH4, carbon and hydrogen share their valence electrons to form a covalent bond.
