Answer the following question given this paragraph: Tapeworms and flukes have suckers and other structures for feeding on a host. Tapeworms also have a scolex , a ring of hooks on their head to attach themselves to the host (see Figure below ). Unlike other invertebrates, tapeworms lack a mouth and digestive system. Instead, they absorb nutrients directly from the host's digestive system with their suckers. Q: What is the ring of hooks tapeworms use to attach themselves? Choices: - cilia - dewlap - flagella - scolex A:
scolex
Answer the following question given this paragraph: Q: What helps frogs swim during the tadpole phase? Choices: - fins - cilia - flagella - a tail A:
a tail
Q: Answer the following question given this paragraph: One example is type 1 diabetes . In this disease, the immune system attacks cells of the pancreas. Other examples are multiple sclerosis and rheumatoid arthritis. In multiple sclerosis , the immune system attacks nerve cells. This causes weakness and pain. In rheumatoid arthritis , the immune system attacks the cells of joints. This causes joint damage and pain. Q: What system is involved in diseases that include type 1 diabetes, rheumatoid arthritis and multiple sclerosis? Choices: - circulatory system - nervous system - digestion system - immune system A:
A: immune system
Question: Answer the following question given this paragraph: Q: What is the name of the formation that regulates sleep and arousal? Choices: - gelechioidea formation - epithelial formation - sleep-arousal formation - reticular formation A:
Answer: reticular formation

Answer the following question given this paragraph: (left) The human respiratory system is only part of the story of respiration. Diaphragm, lungs, and trachea take air deep into the body and provide oxygen gas to the bloodstream. The fate of that oxygen is the story of cellular respiration. (center) Spiracles in this Cluentius Sphinx ( Neococytius cluentius ) caterpillar connect to a system of internal tubes (tracheae), which carry oxygen throughout the animal's body. (right) Gills in this alpine newt larva, Ichthyosaura alpestris , bring blood close to an extensive surface area so that the newt can absorb dissolved oxygen gas from its watery habitat. Q: Diaphragm, lungs, and trachea take air deep into the body and provide oxygen gas to what? Choices: - molecules - heart - brain - bloodstream A:
**Answer**
bloodstream

Answer the following question given this paragraph: 3.4 Protein Synthesis DNA stores the information necessary for instructing the cell to perform all of its functions. Cells use the genetic code stored within DNA to build proteins, which ultimately determine the structure and function of the cell. This genetic code lies in the particular sequence of nucleotides that make up each gene along the DNA molecule. To "read" this code, the cell must perform two sequential steps. In the first step, transcription, the DNA code is converted into a RNA code. A molecule of messenger RNA that is complementary to a specific gene is synthesized in a process similar to DNA replication. The molecule of mRNA provides the code to synthesize a protein. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized. When completed, the mRNA detaches from the ribosome, and the protein is released. Typically, multiple ribosomes attach to a single mRNA molecule at once such that multiple proteins can be manufactured from the mRNA concurrently. Q: In the cellular process of transcription, dna code is converted into what other kind of code? Choices: - dpa - sna - fna - rna A:
**Answer**
rna
