<h2>Answer</h2>
By the attraction between atomic particles of opposite charge
<u>Explanation</u>
An ionic bond is created by the attraction between atomic particles of opposite charge because when the charges are unlike they attract and in this type of attraction there is a complete transfer of charges. In the ionic bond complete transfer of charges takes place. Ionic bonds are formed between elements which have electronegativity changes greater than 1.4 or less than that. It is formed by a combination of cation and anion.
Radiometric dating is a kind of technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
Answer:
having traits that help a single organism survive
Answer:
d
Explanation:
<em>Crossing over shuffles alleles on non-sister chromatids of homologous chromosomes.</em>
At the prophase I stage of meiosis, homologous chromosomes synapsed to form a four-chromatid structure known as tetrad. Exchange of chromosomal segments between non-sister chromatids of the tetrad then takes place, a process that results in the reshuffling of genes or alleles on the non-sister chromatids.
Hence, none of the answers is correct.
Correct option: d
The pH scale is a logarithmic one, meaning that each pH unit has 10 times as many hydrogen ions as the unit above it. So, at pH 4, there are 10 times more hydrogen ions than at pH 5 and 100 times more hydrogen ions than at pH 6.
