Answer the following question given this paragraph: Figure 12.6 Somatic, Autonomic, and Enteric Structures of the Nervous System Somatic structures include the spinal nerves, both motor and sensory fibers, as well as the sensory ganglia (posterior root ganglia and cranial nerve ganglia). Autonomic structures are found in the nerves also, but include the sympathetic and parasympathetic ganglia. The enteric nervous system includes the nervous tissue within the organs of the digestive tract. Q: Somatic, autonomic, and enteric structures are part of what system? Choices: - circulatory system - circulatory system - adrenal system - nervous system A:
nervous system
(Question)

(Answer)
vascular tissue system
Ques: Answer the following question given this paragraph: CHAPTER SUMMARY 21.1 Viral Evolution, Morphology, and Classification Viruses are tiny, acellular entities that can usually only be seen with an electron microscope. Their genomes contain either DNA or RNAnever bothand they replicate using the replication proteins of a host cell. Viruses are diverse, infecting archaea, bacteria, fungi, plants, and animals. Viruses consist of a nucleic acid core surrounded by a protein capsid with or without an outer lipid envelope. The capsid shape, presence of an envelope, and core composition dictate some elements of the classification of viruses. The most commonly used classification method, the Baltimore classification, categorizes viruses based on how they produce their mRNA. Q: Categorized based on how they produce their mrna using the baltimore classification method, what consist of a nucleic acid core surrounded by a protein capsid with or without an outer lipid envelope? Choices: - bacteria - amphibians - parasites - viruses A:
Ans: viruses
(Q).
Answer the following question given this paragraph: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. Q: What is the hypothesis that states that the biosphere is its own living organism? Choices: - Big Bang theory - Geiger theory - Pascal's hypothesis - gaia hypothesis A:
(A).
gaia hypothesis
Ques:Answer the following question given this paragraph: The cell cycle is controlled by a number of protein-controlled feedback processes. Two types of proteins involved in the control of the cell cycle are kinases and cyclins . Cyclins activate kinases by binding to them, specifically they activate cyclin-dependent kinases (CDK) . Cyclins comprise a group of proteins that are rapidly produced at key stages in the cell cycle. Once activated by a cyclin, CDK are enzymes that activate or inactivate other target molecules through phosphorylation. It is this precise regulation of proteins that triggers advancement through the cell cycle. Leland H. Hartwell, R. Timothy Hunt, and Paul M. Nurse won the 2001 Nobel Prize in Physiology or Medicine for their discovery of these critical proteins. Q: What are cyclins made up of? Choices: - enzymes - group of sugars - steroids - group of proteins A:

Ans:group of proteins
Answer the following question given this paragraph: Below the topsoil is the "B" horizon. This is also called the subsoil . Soluble minerals and clays accumulate in the subsoil. Because it has less organic material, this layer is lighter brown in color than topsoil. It also holds more water due to the presence of iron and clay. There is less organic material in this layer. Q: Most waves strike the shore at an angle. this causes what? Choices: - erosion - tide - fontaine drift - longshore drift A:
longshore drift
