Answer the following question given this paragraph: Mercury is the smallest planet. It has no moon. It is also the planet closest to the Sun. Pictured below is the surface of Mercury covered with craters ( Figure below ), like Earth's Moon. Many of the impact craters are billions of years old. This means that Mercury hasn't changed much geologically for billions of years. It has no plate tectonics. With only a trace of an atmosphere, it has no weather to wear down the ancient craters. Q: What is the name of the smallest planet in our solar system, which is also nearest to the sun? Choices: - mars - jupitor - earth - mercury A:
mercury

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:
(Answer)
pap smears
Ques: Answer the following question given this paragraph: An underwater earthquake creates a tsunami this way: The movement of the crust displaces water. The displacement forms a set of waves. The waves travel at jet speed through the ocean. Since the waves have low amplitudes and long wavelengths, they are unnoticed in deep water. As the waves reach shore they compress. They are also pushed upward by the shore. For these reasons, tsunami can grow to enormous wave heights. Tsunami waves can cause tremendous destruction and loss of life. Fortunately, few undersea earthquakes generate tsunami. Q: What type of amplitudes and wavelengths avoid detection in deep water? Choices: - high and long - high and wide - low and wide - low and long A:
Ans: low and long

Answer the following question given this paragraph: 22.1 | Prokaryotic Diversity By the end of this section, you will be able to: Describe the evolutionary history of prokaryotes Discuss the distinguishing features of extremophiles Explain why it is difficult to culture prokaryotes Prokaryotes are ubiquitous. They cover every imaginable surface where there is sufficient moisture, and they live on and inside of other living things. In the typical human body, prokaryotic cells outnumber human body cells by about ten to one. They comprise the majority of living things in all ecosystems. Some prokaryotes thrive in environments that are inhospitable for most living things. Prokaryotes recycle nutrientsessential substances (such as carbon and nitrogen)and they drive the evolution of new ecosystems, some of which are natural and others man-made. Prokaryotes have been on Earth since long before multicellular life appeared. Q: What group of simple organisms recycles nutrients and has been on earth since long before multicellular life appeared? Choices: - bacteria - protists - eukaryotes - prokaryotes A:
(A).
prokaryotes
Ques:Answer the following question given this paragraph: Lighter alkanes wash away protective skin oils; heavier alkanes form a protective layer. Q: How do heavy alkanes affect the skin? Choices: - they do not affect the skin - damage the skin - color the skin - form a protective layer A:

Ans:form a protective layer
Answer the following question given this paragraph: Biotic factors are all of the living or once-living aspects of the environment. They include all the organisms that live there as well as the remains of dead organisms. Q: What are all of the living or once-living aspects of the environment called? Choices: - abiotic factors - photic factors - fossils - biotic factors A:
biotic factors
