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.

Aquatic organisms have only a predatory relationship with coral reefs. Please select the best answer from the choices provided T F.
Aquatic organisms have only a predatory relationship with coral reefs. This statement is false.
What do you mean by coral reefs?It is an underwater ecosystem and is made up of calcium carbonate. They are sessile.
Aquatic organisms have other predators as well depending on the behavior of that particular organisms. There are phytoplankton, zooplankton, small fishes, and large fishes apart from coral reefs in the aquatic ecosystem.
Therefore, Aquatic organisms have not only a predatory relationship with coral reefs.

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.

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.

Which of the following is true of a cell without tRNA?
1. Cell lacking ribosomes
2. mRNA cannot be created at the ribosomes
3. the code of DNA cannot be transferred to the ribosomes
4. Amino acids won't be delivered to the ribosomes
Answer:
double compared to single
Without tRNA, the amino acids won't be delivered to the ribosomes. Hence, option 4 is the correct answer. This is required for the translation process of the cell.
What is the translation process?In the cell, the polypeptide chain is formed by the process of translation. In translation, ribosomes, tRNA, amino acids, and mRNA are involved. The mRNA carries the genetic information. Codons are present in the mRNA. The three consecutive nucleotides make a codon. The tRNA anticodons read the codons, and as per that, amino acids are added. The tRNA carries the amino acids at its 3' end.
The tRNA carrying amino acids is called a charged tRNA. The amino acids are joined by peptide bonds to make a polypeptide chain. Others are incorrect options. Ribosomes are made up of rRNA. mRNA is produced from DNA rather than ribosomes. DNA codes are transferred via mRNA.
Hence, if tRNA is absent within the cell, then amino acids will not be delivered to the ribosome. Option 4 is the correct answer.
