Q: Answer the following question given this paragraph: Most modern plants, like the skunk cabbage, produce flowers. However, flowers evolved relatively late in the history of plants. The earliest plants not only lacked flowers. They also lacked leaves, roots, and stems. They probably resembled the alga in Figure below . Q: The earliest types of what lacked flowers, leaves, roots and stems? A:
Answer: plants

Problem:OPTIONS:
- magnesium
- crystals
- sea salt
- carbonate

Answer the following question given this paragraph: Carbonate minerals are often found where seas once covered the land. Some carbonate minerals are very common. Calcite contains calcium, carbon, and oxygen. Have you ever been in a limestone cave or seen a marble tile? Calcite is in both limestone and marble. Azurite and malachite are also carbonate minerals. They contain copper instead of calcium. They are not as common as calcite. Malachite and azurite are used in jewelry; as you can see, they are very colorful ( Figure below ). Q: What type of minerals are often found where seas once covered the land? A:
****
A: carbonate

Answer the following question given this paragraph: Ozone (O 3 ) depletion in the atmosphere is of significant concern. This gas serves as a protection against the ultraviolet rays of the sun. Ozone is naturally depleted in addition to the depletion caused by human-made chemicals. The depletion reaction is a two-step process:. Q: What done ozone help protect against? A:
OPTIONS:
- gamma rays
- x-rays
- helium rays
- ultraviolet rays
ultraviolet rays

Answer the following question given this paragraph: Floods are a source of nutrients on a floodplain. Q: What are floods a source of on a floodplain? A:
OPTIONS:
- salt
- acids
- minerals
- nutrients

Answer: nutrients

Question: Answer the following question given this paragraph: 3.4 | Protein Synthesis By the end of this section, you will be able to: Explain how the genetic code stored within DNA determines the protein that will form Describe the process of transcription Describe the process of translation Discuss the function of ribosomes It was mentioned earlier that DNA provides a "blueprint" for the cell structure and physiology. This refers to the fact that DNA contains the information necessary for the cell to build one very important type of molecule: the protein. Most structural components of the cell are made up, at least in part, by proteins and virtually all the functions that a cell carries out are completed with the help of proteins. One of the most important classes of proteins is enzymes, which help speed up necessary biochemical reactions that take place inside the cell. Some of these critical biochemical reactions include building larger molecules from smaller components (such as occurs during DNA replication or synthesis of microtubules) and breaking down larger molecules into smaller components (such as when harvesting chemical energy from nutrient molecules). Whatever the cellular process may be, it is almost sure to involve proteins. Just as the cell's genome describes its full complement of DNA, a cell's proteome is its full complement of proteins. Protein synthesis begins with genes. A gene is a functional segment of DNA that provides the genetic information necessary to build a protein. Each particular gene provides the code necessary to construct a particular protein. Gene expression, which transforms the information coded in a gene to a final gene product, ultimately dictates the structure and function of a cell by determining which proteins are made. The interpretation of genes works in the following way. Recall that proteins are polymers, or chains, of many amino acid building blocks. The sequence of bases in a gene (that is, its sequence of A, T, C, G nucleotides) translates to an amino acid sequence. A triplet is a section of three DNA bases in a... Q: The sequence of bases in a gene translates to the sequence of what protein components? A:
OPTIONS:
- protein acids
- rna acids
- molecular acids
- amino acids
Answer: amino acids

input: OPTIONS:
- a cell wall
- a ribosome
- mitochondrial dna
- a nucleus Now, answer this question: Answer the following question given this paragraph: Prokaryotic cells are cells that lack a nucleus. The DNA in prokaryotic cells is in the cytoplasm, rather than enclosed within a nuclear membrane. All the organisms in the Bacteria and Archaea Domains have prokaryotic cells. No other organisms have this type of cell. Organisms with prokaryotic cells are called prokaryotes . They are all single-celled organisms. They were the first type of organisms to evolve. They are still the most numerous organisms today. Q: What significant part of the cell do prokaryotic cells lack? A:
A:
output:
a nucleus
