parasitic
Q: Answer the following question given this paragraph: Figure 21.5 Viruses are classified based on their core genetic material and capsid design. (a) Rabies virus has a single-stranded RNA (ssRNA) core and an enveloped helical capsid, whereas (b) variola virus, the causative agent of smallpox, has a double-stranded DNA (dsDNA) core and a complex capsid. Rabies transmission occurs when saliva from an infected mammal enters a wound. The virus travels through neurons in the peripheral nervous system to the central nervous system where it impairs brain function, and then travels to other tissues. The virus can infect any mammal, and most die within weeks of infection. Smallpox is a human virus transmitted by inhalation of the variola virus, localized in the skin, mouth, and throat, which causes a characteristic rash. Before its eradication in 1979, infection resulted in a 3035 percent mortality rate.

Q: Rabies transmission occurs when saliva from an infected mammal enters a wound. the virus travels through neurons in the peripheral nervous system to the central nervous system where it impairs this? Choices: - lung function - skeletal system - reproduction system - brain function A:
A: brain function
Question: Answer the following question given this paragraph: Arthropods are the largest phylum in the animal kingdom. Most arthropods are insects. The phylum also includes spiders, centipedes, and crustaceans. The arthropod body consists of three segments with a hard exoskeleton and jointed appendages. Terrestrial arthropods have adaptations for life on land, such as trachea or book lungs for breathing air. The earliest arthropods were trilobites. The earliest land arthropods were millipedes. Q: The largest phylum in the animal kingdom, arthropod, is primarily comprised of what? Choices: - reptiles - mammals - amphibians - insects A:
Answer: insects

Answer the following question given this paragraph: All modern classification systems have their roots in the Linnaean classification system. It was developed by Swedish botanist Carolus Linnaeus in the 1700s. He tried to classify all living things that were known at his time. He grouped together organisms that shared obvious physical traits, such as number of legs or shape of leaves. For his contribution, Linnaeus is known as the "father of taxonomy. " You can learn more about Linnaeus and his system of classification by watching the video at this link: http://teachertube. com/viewVideo. php?video_id=169889 . Q: What classification system was developed by a swedish botanist trying to classify all known living things? Choices: - taxonomical system - plantological system - bionumerical system - linnaean system A:
**Answer**
linnaean system
(Q).
Answer the following question given this paragraph: The visible range of light (i. e. the range of wavelengths that our eyes can detect) is a very narrow piece of the full EM spectrum. In the visible range our eyes differentiate between the different wavelengths by producing 'color' for them. When we observe something that is green, it is green to us, because the wavelength of the light hitting our eyes is around 550 nm. If the wavelength of light is slightly larger than this it starts to look red, if it is slightly smaller it looks blue. White light is the combination of all the colors. Black light is the absence of EM waves in the visible spectrum for human beings. Q: What color light is actually the absence of electromagnetic waves in the visible spectrum, for humans? Choices: - ultraviolet light - infrared light - blue light - black light A:
(A).
black light
