The order that the nucleotide are arranged in form different 'codes' to create traits.RNA in human is used for transporting,and making the amino acids proteins.
The order of amino acid proteins also changes the polypeptide formed, changes more traits and characteristics.
Pyrimidines: Cytosine and thymine each have a single six-member ring.
Purines:Guanine and adenine each have a double ring made up of a five-atom ring attached by one side to a six atom ring.
Therefore,they are different, due to nucleotide of our DNA contains four different nitrogenous bases.
To know more about the DNA and RNA nucleotide follow the link:
B. Secondary succession is occurring because the organisms on the forest floor are changing.
C. Climax vegetation is occurring because the seedlings finally have the chance to grow.
D. Primary succession is occurring because more plant life is healthier for the ecosystem.
Answer:
B. Secondary succession is occurring because the organisms on the forest floor are changing.
Psss i just took the quiz
Which of the statements below is true about the alleles for eye color in fruit flies?
A)
The alleles for eye color produce the same phenotype.
B)
The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.
C)
Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population
Answer:
The correct answer would be B) The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.
The amino acid sequence of any protein is determined by the codon sequence of the mRNA which is in turn determined by the nucleotide sequence of the DNA.
Thus, if the nucleotide sequence of the DNA is changed, it will result in the change of amino acid sequence of the protein.
It may result in the change of the structure as well as the function of the protein.
Thus, if the sequence in the gene is changed slightly, it would not result in the production of protein required for a red color trait.
Hence, the eye color of the fruit fly would change to white.
The layer of solid ground that makes up all of Earth’s continents is called the Lithosphere. Thus, the correct option for this question is A.
The lithosphere may be defined as the rigid and outer part of any celestial body like earth. The lithosphere of the earth significantly includes the brittle upper portion of the mantle and the crust along with the outermost layers of Earth's structure.
In the region of the lithosphere, the rocks are cooler, stronger, and more rigid as compared to the other parts of the earth's surface. It is the strength of the rock and the existence of the continents that differentiated the lithosphere from other parts.
Therefore, the lithosphere is the layer of solid ground that makes up all of Earth’s continents. Thus, the correct option for this question is A.

was it the revolution
Outdoor air pollution became a significant problem around the time of the Industrial Revolution due to the increase in industries and coal usage. Heavy industrial cities like London witnessed severe air pollution. However, smaller-scale air pollution has existed since prehistoric times.
Yes, you are correct in assuming that outdoor air pollution became a significant issue around the time of the Industrial Revolution. Beginning in the late 1700s, with the advent of new technology and the increased use of coal as a fuel source, industries began to emit larger amounts of smoke and soot, significantly degrading air quality. Cities fluid in manufacturing, like London, experienced severe air pollution issues, sometimes leading to events such as the 'Great Smog' of 1952. However, it is important to note that forms of air pollution have existed for centuries before the Industrial Revolution, such as dust and smoke from burning wood during the prehistoric era.
