Answer:
1. Elements have only 1 type of atoms
2. Atomic Number
3. Atomic Mass
4. Isotopes
5. Allotropes
Explanation:
An element is a pure chemical substance made of same type of atom.
Elements are distinguished by their name, symbol, atomic number, melting point, boiling point, density and ionization energies. In the Periodic Table, elements are arranged according to their atomic number and they are grouped according to similar chemical properties and are depicted by their symbols.
<em>1. Elements have only 1 type of atoms</em>
<em>2. Atomic Number</em>= Number of protons is also indicative of electric charge or number of electrons present in the nucleus which determines chemical properties of the element.
<em>3. Atomic Mass</em>= the atomic mass of the element which is the total number of protons and neutrons in the nucleus of an atom of the element.
<em>4. Isotopes</em>= isotopes of an element have the same number of protons in their nucleus but differ in the number of neutrons. Naturally occurring elements have more than one stable isotope. Thus isotopes have similar chemical properties (due to same number of protons) but different nuclear properties (due to different number of neutrons).
<em>5. Allotropes</em>= atoms of an element can form bonds with each other in more than one way leading to difference in their chemical properties
Answer:
a genome
Explanation:
A genome is the complete set of genetic information in an organism. It provides all of the information the organism requires to function. In living organisms, the genome is stored in long molecules of DNA called chromosomes.
Answer: The reason is because DNA polymerase which is the enzyme that catalyzes the synthesis of DNA has a 3'->5' exonuclease activity that double-checks each nucleotide after it is added.
Explanation: The 3'->5' exonuclease activity of DNA polymerase allows the enzyme to double-check and remove a newly added wrong nucleotide. It is highly specific for mismatched base pairs. When the DNA polymerase adds a wrong nucleotide to the growing strand, translocation of the enzyme to the position where the next nucleotide is to be added is halted, but the exonuclease activity of the DNA polymerase removes the incorrectly paired nucleotide so that replication can continue. The process of double-checking a newly added nucleotide and removal of any incorrectly paired nucleotide by the DNA polymerase is called proofreading.
The answer is C) The population is growing unchecked. It is not A because the population is changing before our very eyes. It is not B because we know that, yet it has nothing to do with the graph. It is not D because it is still goring up even after the carrying capacity. Actually we don't even know what the carrying capacity is because it does not say. Therefore your answer is C.
