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:
brain function
Answer the following question given this paragraph: Yeasts are an exception. They reproduce asexually by budding instead of by producing spores. An offspring cell forms on a parent cell. After it grows and develops, it buds off to form a new cell. The offspring cell is genetically identical to the parent cell. You can see yeast cells budding in Figure below . Q: How do yeasts reproduce? Choices: - homosexual - preferentially - bisexual - asexually A:
asexually
Q: Answer the following question given this paragraph: Burning forests also releases carbon dioxide into the atmosphere. Other human activities release greenhouse gases into the atmosphere. For example, growing rice and raising livestock both produce methane. Q: Burning forests, growing rice and raising livestock all cause a release of what into the atmosphere? Choices: - oxide gases - carbonate gases - glucose gases - greenhouse gases A:
A: greenhouse gases
Question: Answer the following question given this paragraph: and Z, the atomic number, is the number of protons. The protons and neutrons that make up the nucleus of an atom are callednucleons, and an atom with a particular number of protons and neutrons is called anuclide. Nuclides with the same number of protons but different numbers of neutrons are called isotopes. Isotopes can also be represented by an alternative notation that uses the name of the element followed by the mass number, such as carbon-12. The stable isotopes of oxygen, for example, can be represented in any of the following ways:. Q: What are protons and neutrons that make up the nucleus of an atom called? Choices: - baryons - pions - electron shells - nucleons A:
Answer: nucleons

Answer the following question given this paragraph: A: Earth has north and south magnetic poles. The North Pole is located at about 80 degrees north latitude. The magnetic field is an area around Earth that is affected by its magnetic field. The field is strongest at the poles, and lines of magnetic force move from the north to the south magnetic pole. Q: What is located at about 80 degrees north latitude? Choices: - alaska - india - the equator - the north pole A:
**Answer**
the north pole
