Question: Melinda lived on The Big Island of Hawaii. One day she invited her Australian friend Janice over to visit the islands. Janice was very excited about the invitation. Which person invited Janice to visit the youngest island of the chain? Hint: The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loih
Answer: Melinda

[Q]: Bubba and Dean are two farmers which realized the benefits of having AM fungi in their soil. Dean, however, took active steps in helping the growth of AM fungi so he grew cover crops on his lands. Which farmer didn't increase the extraradical hyphal network that can colonize the roots of the new crop? Hint: Since AM fungi are biotrophic, they are dependent on plants for the growth of their hyphal networks. Growing a cover crop extends the time for AM growth into the autumn, winter, and spring. Promotion of hyphal growth creates a more extensive hyphal network. The mycorrhizal colonization increase found in cover crops systems may be largely attributed to an increase in the extraradical hyphal network that can colonize the roots of the new crop (Boswell et al. 1998). The extraradical mycelia are able to survive the winter, providing rapid spring colonization and early season symbiosis (McGonigle and Miller 1999). This early symbiosis allows plants to tap into the well-established hyphal network and be supplied with adequate phosphorus nutrition during early growth, which greatly improves the crop yield.

input: Please answer the following: John is a marine biologist. He was collecting samples from six locations in the ocean, location A, location B, location C, location D, location E, and location F. Location A was near the shore, but location B was farther offshore. Location C was in shallow water, but location D was deeper into the ocean. Location E was a habitat with very few organisms, but location F was a habitat full of organisms. Which location would see less viruses, location C or location D? Hint: The number of viruses in the oceans decreases further offshore and deeper into the water, where there are fewer host organisms.In January 2018, scientists reported that 800 million viruses, mainly of marine origin, are deposited daily from the Earth's atmosphere onto every square meter of the planet's surface, as the result of a global atmospheric stream of viruses, circulating above the weather system, but below the altitude of usual airline travel, distributing viruses around the planet.Like any organism, marine mammals are susceptible to viral infections. In 1988 and 2002, thousands of harbour seals were killed in Europe by phocine distemper virus. Many other viruses, including caliciviruses, herpesviruses, adenoviruses and parvoviruses, circulate in marine mammal populations.

Please answer this: Joe studied the lives of humans. He studied 2 groups of people. Group G had people over 65 in it, and group Y had people under 65 years old in it. Which group had fewer people that had decreased stamina? Hint: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common.

Problem: Keith landed a job with the EPA. As part of his training he needed to learn how the Geiger counter works. To learn more about the counter he tested it in three different locations, location A, location B, and location C. Location A had very high radiation; location B had low radiation; and location C didn't have any radiation. Keith learned how the counter works in locations with varying degrees of radiation. In which location the Geiger counter would click, location A or location C? Hint: You generally can't see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below.

input: Please answer the following: Two researches studied living organisms, Joe studied eukaryotes, while Bill studied prokaryotes. They were fascinated by genetic variation. Which researcher observed more membranes of two cells merging? Hint: Prokaryotes have a different way to increase genetic variation. It's called genetic transfer or bacterial conjugation . It can occur in two ways. One way is when cells "grab" stray pieces of DNA from their environment. The other way is when cells directly exchange DNA (usually plasmids) with other cells. For example, as shown in Figure below , the donor cell makes a structure called an F pilus , or sex pilus. The F pilus attaches one cell to another cell. The membranes of the two cells merge and genetic material, usually a plasmid , moves into the recipient cell. Genetic transfer makes bacteria very useful in biotechnology. It can be used to create bacterial cells that carry new genes.
