DNA provides a very significant role in the formation and development of an organism.what is that role?
Answer:
The significant role that DNA provides is the organism's genetic information. It stores its information inside, and that's what makes up all the traits of the organism. All known cellular life contains DNA for this reason, and basically serves as long-term storage of information about the organism.

ILL GIVE BRAINLY PLZ HELP Fisherman at Reelfoot Lake, in Northwest Tennessee, noted a drop in the number of catfish. What is the most reasonable conclusion, based on the data provided?
A) The pH of the rain will not affect the fish that live in the lake.
B) The pH of the rain falling into the lake is of level that it is killing the adult fish.
C) The pH of the rain falling into the lake is of level that it is affecting fish reproduction.
D) The pH of the rain falling into the lake is of level that it is both affecting fish reproduction and killing adult fish.
Answer:
D, if you look at the acid rain it covers both death of fish and reproduction
Fecal coliform is an indicator of what type of disease?
Answer:
Explanation:
Some waterborne pathogenic diseases include typhoid fever, viral and bacterial gastroenteritis and hepatitis A. The presence of fecal contamination is an indicator that a potential health risk exists for individuals exposed to this water.
Answer:
Thermotolerant coliform bacteria (commonly referred as fecal coliforms) are the group most frequently used as indicators of fecal pollution because they behave in a similar way to most pathogenic bacteria in the environment, and, during treatment, they are abundant and easy to determine.
4 pros and 4 cons of nuclear desalination
20 points
Four pros of nuclear desalination; nuclear desalination provides accessible drinking water, helps with habitat protection, provides water to the agricultural industry, and uses a large amount of energy.
Four cons of nuclear desalination; Waste Disposal, nuclear desalination could lower down Ocean populations, nuclear desalination creates Health Concerns, and uses energy.
Which compound forms when carbon dioxide diffuses and reacts with seawater?
A. Hydroxide ions
B. Carbonate
C. Bicarbonate
D. Carbonic acid
Answer:
It's D
Explanation:
When CO2 reacts with water first carbonic acid is produced. then this carbonic acid will transform to H+ and HCO3-.
BUT BECAUSE FIRST CARBONUC ACID IS PRODUCED SO CARBONIC ACID IS CORRECT.
hope you understand.

Answer:
C-U-A-G-G-A
Explanation:
took the quiz this question right with this answer
The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.

A student collects a sample of water from a pond near her home. She
examines a drop of the water under a microscope and sees four very
differently shaped single-celled organisms. Which of the following
can she reasonably conclude as the reason the organisms look so
different?
Answer:
A. Each organism had a different parent that passed on a set of unique genetic instructions.
Explanation:
Organisms can either be single-celled or multicellular. According to this question, a student collects a sample of water from a pond near her home. She then examines a drop of the water under a microscope and noticed it contains four very differently shaped single-celled organisms.
The single-celled organisms are of different shapes because they are from different parents, which passed on a set of unique genetic instructions via their genes to them. Organisms of the same species from the same parent will possess the same shape because they contain same gene which makes them look and behave similar.
However, in this case, the four different shaped single-celled organisms are of DIFFERENT SPECIES and hence, contain individual unique genes that makes them so
