Answer:The constituents of a solid can be arranged in two general ways: they can form a regular repeating three-dimensional structure called a crystal lattice, thus producing a crystalline solid, or they can aggregate with no particular order, in which case they form an amorphous solid (from the Greek ámorphos, meaning
Explanation:
A.
all the DNA strands in the two DNA molecules will have both parental and newly synthesized DNA.
B.
it results in two nonidentical DNA molecules.
C.
each of the two DNA molecules will consist of one parental strand and one newly synthesized strand.
D.
of the two DNA molecules, one is made up totally of parental DNA, while the other is entirely newly synthesized DNA.
E.
one DNA strand is replicated continuously, while the other must be replicated discontinuously.
DNA analysis
light microscopy
electron microscopy
Electron microscopy has enabled the greatest advances in understanding law of inheritance. Thus, option D is correct.
Inheritance can be defined as the process by which an offspring can carry genetic information from their parent.
Gregor Mendel who first postulated laws of inheritance while doing hybridization experiment on garden pea plant.
He proposed three laws
First Law of Dominance states that In an organism, a character express in two forms or allele.
In F1-progeny the allele which is expressed is called dominant, while the other remain masked is called recessive allele.
Second Law of segregation which states the alleles do not show any mixing and both the traits are appeared in F2-generation.
Third Law of Independent Assortment states that when two pairs of characters are combined, separation of one pair of trait is independent of other pair segregation of one pair of character.
Thus, option D is correct.

DNA Analysis
Explanation:
Answer:
Increase occurs in fresh water input.
Decrease occurs in the salinity of the bay.
Explanation:
The low rate of fresh water input and the presence of high amount of salts in water decreases the population of producers such as grasses in bay ecosystem. Due to this decrease, the population of the marine animals decreases due to the low availability of food for herbivorous organism that lives in the bay. The negative feedback mechanisms will be achieved if increase occurs in fresh water input and decrease occurs in the salinity of the bay.
Argon is a chemical element which is a gas at room temperature, has 8 valence electrons and 22 neutrons. This element belongs to the noble gas elements group.
Noble gas is any of the rare gases that include helium, neon, argon, krypton, xenon, and sometimes radon also and that exhibit great stability and extremely low reaction rates than other elements in the periodic table.
Argon is a chemical element with the symbol Ar and it has an atomic number of 18. It is in the group 18 of the periodic table and it is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.9340 ppmv. It is more than twice as abundant as that of water vapor, 23 times as abundant as carbon dioxide, and more than 500 times as abundant as neon gas. Argon is the most abundant noble gas in the Earth's crust, which comprises about 0.00015% of the crust.
