Answer:
<u>Frederich Miescher</u>- first person to isolate DNA and RNA
<u>Frederick Griffith</u>- first to demonstrate horizontal transmission of dna using bacteria
<u>Gregor Mendel</u>- documented and demonstrated inheritance patterns
Thomas Hunt Morgan- identified chromosomes as the structures responsible for inheritance
<u>Joachim Hammerling</u>- demonstrated that the hereditary information of of eukaryotes is contained within the nucleus
<u>Alfred Hershey and Martha Chase</u>- demonstrated that dna not protein was the molecule responsible for hereditary
<u>George Beadle and Edward Tatum</u>- used mutants to show the relationship between DNA and proteins
<u>Albrecht Kossel</u>- characterized the structure of adenine, guanine, cytosine, thymine, and uracil

Hope this helps! Pls give brainliest!
None because Covalent compounds don’t conduct electricity because they are formed between the non metal atoms by sharing of electrons. The Covalent compounds haves no free electrons and also no ions and hence they do not conduct electricity. That is why they do not conduct electricity.
Answer:
metallic bonding is the bond form between two or more metal elements or between metal element and the other group elements
Answer:
Yes , 5 mole of Iron Oxide has mass of 798.5 g
Explanation:
Formula of iron oxide:
Atomic mass of Fe = 55.84 amu
Atomic mass of O = 15.99 amu
Molar mass of Fe2O3 = 2(atomic mass of Fe) + 3(atomic mass of O)
= 2(55.84) + 3(15.99)
=111.68 + 47.97
= 159.69 g/mol
<u>Molar mass</u> always equal to <u>1 mole</u> of the substance.
1 mole = 159.69 g
5 mole =
= 798.45 g
