Explain the relationship between the second law of thermodynamics and the net energy of an
Anton [14]

Answer:

The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered state

is that helpful?

Put the following events in the correct order:
Wewaii [24]

Answer:

Explanation:

c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.

b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.

The process of deoxyribonucleic acod starts with replication to transcription and translation.

Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.

transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.

Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

Hence the arrangement is from C ---- A-----B.

The proportions of the bases are consistent within a species; however they do vary between species. Using the base-pair rules, c
Snezhnost [94]

Answer:

The correct answer would be:

                  A         G          C         T

Human:   31          19          19       31

Cow:         28         22      22         28

Salmon:     29       21       21         29

Wheat        27      23        23        27

Yeast         31         19       19         31

Explanation:

According to the rule of Chargaff which states or explains the amount of the A, T, G, and C bases in the DNA molecule. It says that the DNA of any organism should have a pyrimidine and purine ratio of 1:1. This means the amount of A would be equal to T and the amount G should be equal to the amount of C.

It also says that the amount of a and G would be equal to the amount of C and T. So on the base of this we can find the missing value in the table:

                    A         G          C         T

Human:   31          19          19       31   (A= T and G=C)

Cow:         28         22      22         28  (A= T and G=C)

Salmon:     29       21       21         29   (A= T and G=C)

Wheat        27      23        23        27 (100 - A+T = G+C)

Yeast         31         19       19         31 (A= T and G=C)

What characteristic is shared by both inceptisols and entisols, the soils of flood plains?
marysya [2.9K]

<u>Answer</u>:

"Both are young and only beginning to develop horizons and a soil profile"is the characteristic  shared by both inceptisols and entisols, the soils of flood plains

<u>Explanation</u>:

Inceptisols and entisols are the soils that are seen in the floodplains. These soils are very weakly withered and also lacks organic matter. They are the sediments that comes from several other places through flood. The soil order of inceptisols in USDA in the soil taxonomy because they have the capability to form by the change of parent material. Also they are known to be more developed than that of entisols. Presence of clay, iron oxide, aluminium oxide and organic matters are also not found. But the entisols can not be changed from that of parent material. They are either rock or sediments.
