The subject area of Chemistry is a very broad area. So, it is classified into sub-branches like inorganic chemistry, organic chemistry, physical chemistry, quantitative chemistry and many more. But when the basis is on the composition of elements, it is divided into inorganic and organic chemistry. Compounds containing the element Carbon are all under organic chemistry. If they do not contain carbon, they are considered as inorganic.
During the early times, the only differentiation between these two sub branches is the vital theory. This theory proposes that all things that have life can be only made by nature alone are inorganic. But thing was disproved by Wohler when he was able to synthesize urea from inorganic compounds. Thus, today the only differentiation is the carbon atom.
Answer:
The fundamental law of inheritance.
Explanation:
He is responsible for our knowing that genes come in pairs and are inherited as units (alleles), one from each parent.
Answer:
GAA TTC GCA Original strand
CTT AAG CGT Complimentary strand
Explanation:
The original strand is already given. It is GAA TTC GCA
Now we need to recognize the complementary strand from the pool of options and pair their bases. Names are written with their letters.
Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines.
- Adenine (A) and guanine (G) derive from purines,
- Thymine (T) and Cytosine (C) derive from Pyrimidines.
In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.
Knowing this, we need to find the correct option, which will pair A with T and C with G.
- 1st Strand → CUU AAG CGU → You can eliminate this option because it includes Uracil, which is a base of RNA. Uracil complements with Adenine, but only in RNA, and now we are looking for a DNA complementary strand.
- 2nd Strand → GAA CCT CAT → None of the triplets pair correctly the original strand. It is not complementary
- 4rth Strand → GAA TTC GCA → This is equal to the original strand. It does not complement it.
- 3rd Strand → CTT AAG CGT → The three triples complement the ones of the original strand. This is the correct option.
G ⇔<em>C</em>
A ⇔ <em>T</em>
A ⇔ <em>T</em>
T ⇔ <em>A</em>
T ⇔ <em>A</em>
C ⇔ <em>G</em>
G ⇔ <em>C</em>
C ⇔ <em>G</em>
A⇔ <em>T</em>

Answer:
Sharing electrons occurs when atoms have a covalent bond. Covalent bonds occur between non-metals and there are two types of covalent bonds: Polar and Nonpolar Covalent bonds. Polar covalent bonds are when there is an unequal sharing of electrons which causes the atom that occupies the electron(s) more to have a slightly negative charge while the atom that occupies the electron(s) less has a slightly positive charge. Nonpolar covalent bonds basically have equal sharing of the electron(s).
Atoms bond because they need to become stable like the noble gases.
