2881. In malaria, the body temperature may rise as high as:

• A. 102°F
• B. 104°F
• C. 106°F
• D. 107°F
• E. 106°C

Explanation: Malaria can cause high fevers as part of its symptomatology, especially in severe cases. A body temperature of 106°F (41.1°C) is indicative of an extreme fever, which can occur during the peak of a febrile paroxysm in malaria. Options like 102°F and 104°F, while high, do not capture the severity possible in malaria-induced fevers. Temperatures like 107°F and 106°C are either dangerously high or impossible for human survival, making them incorrect choices.

2882. Which of the following is not a symptom of malaria?

• A. Headache
• B. Muscular pains
• C. Constipation
• D. Chills
• E. Flu-like symptoms

Explanation: Constipation is not a typical symptom of malaria. Malaria commonly presents with symptoms that affect the body's temperature regulation and mimic flu-like conditions, such as fever, chills, headache, and muscular pains. Headache, muscular pains, chills, and flu-like symptoms are all consistent with malaria. Constipation, however, is not usually related to malaria, which primarily impacts the body's febrile and respiratory systems.

2883. Concerning 'LAVA' which statement is not correct?

• A. The plant body is called thallus
• B. Sporophyte is thallus with 26 chromosomes
• C. Gametophyte is thallus with 26 chromosomes
• D. Reproduction is by sexual as well as asexual methods
• E. It is found growing along the sea-coasts between high and low tides.

Explanation: The correct answer is Option D: 'Reproduction is by sexual as well as asexual methods.' This statement is typically true for many algae species, which exhibit both reproductive modes. The other options are incorrect because they either present misleading chromosome counts for life cycle stages (Options B and C) or describe general characteristics of algae that do not necessarily pinpoint an incorrect statement about 'LAVA' (Options A and E).

2886. What was the correct classification according to Linnaeus?

• A. Similar genera in one family
• B. Similar species in one genus
• C. Similar familes in one order
• D. All of above

Explanation: Linnaean classification indeed involved grouping organisms hierarchically based on similarities, encompassing similar species in one genus, similar genera in one family, and similar families in one order. Therefore, the accurate choice is "All of the Above." Linnaeus organized living organisms into a nested hierarchy that considered similarities at various taxonomic levels.
