Answer the following question given this paragraph: A community is made up of the relationships between groups of different species. For example, the desert communities consist of rabbits, coyotes, snakes, birds, mice and such plants as sahuaro cactus, ocotillo, and creosote bush. Community structure can be disturbed by such dynamics as fire, human activity, and over-population. Q: The relationships between groups of different species makes up a ___________. Choices: - species - family - food chain - community A:
community

Ques: Answer the following question given this paragraph: The prevalence of cervical cancer in the United States is very low because of regular screening exams called pap smears. Pap smears sample cells of the cervix, allowing the detection of abnormal cells. If pre-cancerous cells are detected, there are several highly effective techniques that are currently in use to remove them before they pose a danger. However, women in developing countries often do not have access to regular pap smears. As a result, these women account for as many as 80 percent of the cases of cervical cancer worldwide. In 2006, the first vaccine against the high-risk types of HPV was approved. There are now two HPV vaccines available: Gardasil®️ and Cervarix®️. Whereas these vaccines were initially only targeted for women, because HPV is sexually transmitted, both men and women require vaccination for this approach to achieve its maximum efficacy. A recent study suggests that the HPV vaccine has cut the rates of HPV infection by the four targeted strains at least in half. Unfortunately, the high cost of manufacturing the vaccine is currently limiting access to many women worldwide. Q: The prevalence of cervical cancer in the united states is very low because of regular screening exams called what? Choices: - prostates exams - mammograms - Stavros smears - pap smears A:
Ans: pap smears

Ques:Answer the following question given this paragraph: All life relies on a relatively narrow range of pH, or acidity. That's because protein structure and function are very sensitive to pH. Air pollution can cause precipitation to become acidic. Nitrogen and sulfur oxides, mainly from motor vehicle exhaust and coal burning, create acids when they combine with water in the air. The acids lower the pH of precipitation, forming acid rain . If acid rain falls on the ground, it may damage soil and soil organisms. If it falls on plants, it may kill them (see Figure below ). If it falls into lakes, it lowers the pH of the water and kills aquatic organisms. Q: When the ph of precipitation is lowered because of air pollution, what results? Choices: - abnormal rain - climate change - sleet - acid rain A:

Ans:acid rain
