Question: I can use this background: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. Now, I have a new situation: Students learned about protozoa in school this week. Dan and Jim were interested and read more on the subject. Dan read more about predatory protozoa, while Jim read more about herbivore protozoa. Answer this question please: Which student read more about protozoa preying upon single-celled organisms?
Answer: Dan

Question: I can use this background: Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and EpsteinBarr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years. Now, I have a new situation: The Jones family had a history of chronic viral infections. Jenny got human papillomavirus, while her brother Josh got infected with the EpsteinBarr virus. They were both under treatment. Answer this question please: Which sibling had a lower risk of developing Hodgkin's lymphoma?
Answer: Jenny

Question: I can use this background: A few insects, such as mayflies and some moths, never eat. That's because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried. Now, I have a new situation: Two entomologists liked studying all types of insects and arthropods. Bill was focused on insects that never eat. His buddy Paul was more focused on the feeding habits of other insects that eat a lot of food. Answer this question please: Which friend didn't learn that a locust eats its own weight in plants every day?
Answer:
Bill
