Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.
According to the information given above, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.
What are Bases?Bases may be defined as the monomer of nucleic acids such as DNA or RNA. These nucleotide bases are composed of a pentose sugar, and a phosphate group.
There are four types of nucleotide bases that are generally found in any nucleic acid sequence. They are adenine, guanine, thymine, and cytosine. But in RNA, Thymine is replaced by Uracil.
According to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.
∴ A = T : G = C.
If the amount of adenine is 20%, the amount of thymine is also 20%. Together, they constitute 40% of DNA, now the remaining is 60%.
This 60% is then equally divided into two parts between 30% cytosine and 30% guanine.
Therefore, the amount of the three remaining bases for this sample is 30% cytosine, 20% thymine, and 30% guanine. Thus, the correct option is B.

Describe three ways to reduce the practice of shark finning.
Answer:
If you know that a restaurant is serving shark fin, raise awareness of shark finning with the people that you eat with. Tell them about the cruel practice and try to convince them to also stop going to the restaurant. If the restaurant sees a decline in customers, then they might stop serving shark fin.
why physiological can occur during hibernation?
Answer:
Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism. Research into the processes involved in hibernation could result in medical benefits for people
Explanation:
what is the role of carbon in living organisms
Answer:
All living things contain carbon in some form. Carbon is the primary component of macromolecules, including proteins, lipids, nucleic acids, and carbohydrates. Carbon's molecular structure allows it to bond in many different ways and with many different elements.

Which statement is correct regarding the semiconservative nature of DNA?
A. RNA operates as a template to allow DNA to replicate itself using ribosomes
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
C. The semiconservative nature of DNA allows for genetic continuity in gamete production
D. The structure of the sugars on the DNA molecule direct the correct nucleotides into place during replication
I need the answer fast, this is a 40 point and i will put you as brainliest
Answer:
B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made
Explanation:
DNA replication is the process whereby the contents of DNA is doubled or duplicated. In other words, another copy of DNA is produced from one DNA molecule. The process follows the semi-conservative model, which generally speaks of how one template strand is used to synthesize another new strand.
In the semi-conservative model of DNA replication, the double strand of DNA is unwind and one of the strands called parent strand is used synthesize a complementary strand of DNA. At the end of the process, two DNA molecules results with each having one old strand and one new strand. Nitrogenous bases or nucleotides in each "parent" strand" serve as a template for the new strand to be made.

how might a healthy, actively hunting wolf pack impact the elk herd population density?
The elk herd population density will decrease the density by feeding off them, however, if it's a healthy balanced amount.
What do you mean by population density?Population density is the average number of individuals in a population per unit of area or volume. For example, a population of 100 insects that live in an area of 100 squar e meter s has a density of 1 insect per square meter.
The number of individuals living within that specific location determines the population density, or the number of individuals divided by the size of the area. Population density can be used to describe the location, growth, and migration of many organisms
To calculate density, you divide the number of objects by the measurement of the area. The population density of a country is the number of people in that country divided by the area in square kilometers or miles.

Which of the following would give a person the most energy?
a starch
a monosaccharide
a disaccharide
glucose
Answer:
I THINK IS D
Explanation:
The following that would give a person the most energy is glucose. The correct option is D.
What is glucose?Glucose is a monosaccharide ad it is the primary source of energy in plants and animals. The cells produce energy by converting food into glucose molecules.
Its structure is simple. It is a simple carbohydrate. The formula is C6H12O6. It is made up of carbon, hydrogen, and oxygen. It is the only form and basic form of energy.
Every plant and animal produce glucose by body function, and if there is excess glucose in the body, the body saves it in the form of glycogen in the adipose tissues.
In all others, starch does not produce energy. It gives structural strength to the body, and disaccharides are a unit, but not all disaccharides provide energy to the body.
Thus, the correct option is D. glucose.
