Plant Hormones and Flowering in Pineapple

Plant Physiology

• Auxin and Ethylene can be applied to artificially induce flowering in pineapple plants throughout the year to increase yield.
• Gibberellin and Abscisic acid are not a suitable combination of hormones for artificial flowering.

Bacteria and Toxins

• The Bt toxin of Bacillus thuringiensis is activated in the boll worm by the moist surface of the midgut and alkaline pH of the gut.
• Acidic pH of the stomach is not involved in the activation of Bt toxin.

Human Health

• Goblet Cells are the cells that secrete mucus, which protects the lining of the gastro-intestinal tract from various enzymes.
• Streptococcus pneumoniae is not the causative agent of typhoid fever.
• Salmonella typhi is the causative agent of typhoid fever, and the Widal test is the confirmatory test for typhoid.

Biocontrol Agents

• Trichoderma can be used as a biocontrol agent in the treatment of plant diseases.

Genetic Disorders

• An individual with an overall masculine development, gynaecomastia, and sterility is likely to have a genetic disorder.

Botany

• Phloem in gymnosperms lacks sieve tubes.
• Pinus seeds cannot germinate and establish themselves without fungal association because they have an obligate association with mycorrhizae.

Genetics

• The ratio of F2 is 1:2:1 (Red: Pink: White).
• The law of segregation does apply in this experiment.

Biochemistry

• Conversion of glucose to glucose-6-phosphate is catalyzed by Hexokinase.
• Phosphofructokinase is not the enzyme that catalyzes the first irreversible reaction of glycolysis.

Biotechnology

• Genetic code is nearly universal, allowing bacteria to produce human insulin by recombinant DNA technology.
• Heroin is synthesized by acetylation of morphine.

STDs

• One of the sexually transmitted diseases that is not completely curable is not specified.

Animal Characteristics

• Annelida, Arthropoda, and Chordata are the animal groups that possess true coelomates with segmentation of the body and bilateral symmetry.

Respiratory Quotient

• Respiratory Quotient (RQ) value of tripalmitin is 0.7.

Medicines

• Statin is a commercial blood cholesterol-lowering agent.
• Cyclosporin A, Streptokinase, and Lipases are not blood cholesterol-lowering agents.

Conservation Biology

• In situ conservation of biodiversity is not done by the method mentioned.
