The ozone molecule consists of three atoms of oxygen (O₃).
Answer:
4 miles north
Explanation:
Initially Scott travels 5 miles north at this point his displacement is 5 miles toward north
then he goes 3 miles south. which makes his displacement 2 miles (5 - 3 = 2) towards north as north and south are opposite directions.
finally he travels 2 miles due north.so his final displacement is
2 miles + 2 miles = 4 miles towards north direction
Answer:
The catabolic process of converting carbohydrates to CO2 requires<u> oxidation</u> of carbon.
Explanation:
There are multiple definitions of reduction-oxidation. There is one that explains it with respect to oxygen, the other with respect to hydrogen and another with respect to electrons. The relevant one here is the one that explains it in terms of hydrogen. Oxidation is the removal of hydrogen while reduction is the addition of hydrogen. During repiration, the carbon loses the hydrogens attached to it and is therefore oxidized. These hydrogens attach themselves to oxygen which means oxygen is reduced.
The elements are placed in specific places on the periodic table based on their atomic number and outer electronic configuration which gives them certain properties.
The elements of same groups have same number of valence electrons.
Group 1: one electron in valence shell
Group 2: two electrons in valence shell.
Helium has only two electrons in its outer shell and it is grouped with elements that have completely filled outer orbitals, noble gas.
Answer:
<h2>ATP, RNA, NAD and DNA.</h2>
Explanation:
A nitrogenous base; it is an organic molecule containing a nitrogen, carbon and other atoms that has the chemical properties of a base that is why they are called as bases. The nitrogenous bases are; i) adenine, ii) guanine, iii) thymine, iv) uracil and v)cytosine.
Adenine is a nitrogenous base which is found in ATP, RNA. NAD, FAD and DNA. adenine pairs with thymine in DNA synthesis.
