PLS HELP SUPER HARD 100 POINTS Ian dissects a frog in science class and is interested in the heart. He studies a diagram of the human heart to compare them. He finds that a frog’s heart has two atria and a single ventricle. He returns to the human heart diagram and reads that it is considered a double loop system.
In the center of the diagram is a small round object, with a cutaway to see inside. Inside are two main sections separated by a thick line. The section on the left of the diagram is labeled right side of the heart. There are arrows pointing down and curving back up into a dark tube. The section on the right of the diagram is labeled left side of the heart. There are arrows pointing down from a light tube and then back up. On top of the diagram is a looped tube. One end of the tube is darker and labeled arteries. It is connected to the top of the right side of the heart section, and it has arrows pointing upward. At the top of the diagram the tube splits into smaller tubes labeled, capillaries. The smaller tubes join back into a single, lighter tube, which is labeled veins. This portion of the tube is connected to the top of the left side of the heart section. It has one arrow pointing down. At the bottom of the diagram is a second looped tube. One end of the tube, is lighter and labeled arteries. It is connected to the top of right side of the heart section, and it has arrows pointing downward. At the bottom of the diagram the tube splits into smaller tubes labeled, capillaries. The smaller tubes join back into a single, darker tube, which is labeled veins. This portion of the tube is connected to the top of the right side of the heart section. It has arrows pointing upward.
Why is the human heart called a double loop system?
A. There are two sections, or loops, that each have the same job in the circulatory system.
B. One loop passes through the heart on the way to the body, and the other loop passes through the body to the lungs.
C. One loop takes blood with oxygen to the lungs, and the other loop takes blood and wastes to the body.
D. One loop takes blood with wastes to the lungs, and the other loop takes blood with oxygen to the body.
Answer:
D. One loop takes blood with wastes to the lungs, and the other loop takes blood with oxygen to the body.
Explanation:
The first loop takes blood with wastes to the lungs so that it can be breathed out during exhalation - this could be carbon dioxide and water vapour. The other loop takes oxygenated blood to the body so that cells can use the oxygen and glucose for respiration to release energy.

Is it worth it to genetically modify food? Consider the risks and benefits of genetically modified foods in farming in your answer.
Answer:
no is not hygienic because it's not healthy
Answer:
The bottom line is that while there are benefits to GM crops, there are substantial downsides. Remove the herbicide resistance, and the benefits increase a lot. GM technology may also one day prove useful in other ways, e.g. helping adapt crops to climate change by introducing genes for heat or drought resistance.

A researcher determines an organism to be eukaryotic, unicellular, and autotrophic. In which taxonomic group should this organism be classified
According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.
What is the kingdom protista?It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.
Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.
Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.

Explanation:
How an mRNA is synthesized using a gene
The nucleus uses the nucleotide sequence of DNA as a template to make mRNA. The enzyme RNA polymerase II catalyzes this activity, which requires nucleotide triphosphates as substrates. Transcription is the process of producing mRNA from DNA, and it takes place in the nucleus. The DNA of a gene serves as a template for complementary base-pairing during transcription, and an enzyme known as RNA polymerase II catalyzes the synthesis of a pre-mRNA molecule, which is then processed to generate mature mRNA.

Gene control mechanisms, or "gene expression," control _____.
A kinds and amounts of proteins in a cell
B DNA replication
C mRNA translation
D protein synthesis
Answer:
I believe the correct answer is C. mRnA translation.
Explanation:
Because the gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.

Describe how a nonpolar to polar R group substitution changes the structure and function of a protein.
A nonpolar to polar R group substitution changes the structure and function of a protein because polar structure can dissolved polar and non-polar can dissolve non-polar.
Why change of nonpolar to polar affect structure and function of protein?The change of nonpolar to polar leads to change in structure and function of protein because the arrangements of atoms are different which leads to change of function as well.
So we can conclude that nonpolar to polar changes the structure and function of a protein because polar structure can dissolved polar and non-polar can dissolve non-polar.
