organism
(Question)
Answer the following question given this paragraph: Maturation of the ovum. Notice only 1 mature ovum, or egg, forms during meiosis from the primary oocyte. Three polar bodies may form during oogenesis. These polar bodies will not form mature gametes. Conversely, four haploid spermatids form during meiosis from the primary spermatocyte. Q: Four haploid spermatids form during meiosis from what? Choices: - the zygote - the sister chromatic - the ova - the primary spermatocyte A:
(Answer)
the primary spermatocyte

Ques:Answer the following question given this paragraph: The Cellular Basis of Immunological Memory As already discussed, one of the major features of an adaptive immune response is the development of immunological memory. During a primary adaptive immune response, both memory T cells and effector T cells are generated. Memory T cells are long-lived and can even persist for a lifetime. Memory cells are primed to act rapidly. Thus, any subsequent exposure to the pathogen will elicit a very rapid T cell response. This rapid, secondary adaptive response generates large numbers of effector T cells so fast that the pathogen is often overwhelmed before it can cause any symptoms of disease. This is what is meant by immunity to a disease. The same pattern of primary and secondary immune responses occurs in B cells and the antibody response, as will be discussed later in the chapter. Q: Memory t cells are long-lived and can even persist for how long? Choices: - eons - days - minutes - lifetime A:

Ans:lifetime
Question: Answer the following question given this paragraph: Mesophiles grow best in moderate temperature, typically between 25C and 40C (77F and 104F). Mesophiles are often found living in or on the bodies of humans or other animals. The optimal growth temperature of many pathogenic mesophiles is 37C (98F), the normal human body temperature. Mesophilic organisms have important uses in food preparation, including cheese, yogurt, beer and wine. Q: What type of organism is commonly used in preparation of foods such as cheese and yogurt? Choices: - protozoa - gymnosperms - viruses - mesophilic organisms A:
Answer:
mesophilic organisms
