Flight‑tracking studies show insects usually do not fly directly toward lights; instead they tilt their dorsum toward the brightest region, disrupting flight orientation.
3
[ "biology-0/extraction_0.txt" ]
biology-0-a2
Many insects exhibit positive phototaxis and strong responses to visible wavelengths, especially shorter wavelengths like UV and blue light.
2
[ "biology-0/extraction_1.txt", "biology-0/extraction_5.txt" ]
biology-0-a3
If heat attraction were the primary mechanism, lights lacking infrared radiation should not attract insects, yet LEDs still trap many.

biology-1-a1
Humans exhibit a nasal cycle where airflow alternates between nostrils because one nasal passage becomes partially obstructed while the other opens.
3
[ "breathe_out_of_one_nostril/Nasal_cycle_0.txt", "biology-1/extraction_2.txt" ]
biology-1-a2
This alternation occurs because blood‑filled nasal turbinates periodically swell on one side and shrink on the other, changing resistance and airflow.
3
[ "breathe_out_of_one_nostril/Nasal_cycle_1.txt" ]
biology-1-a3
Asymmetric airflow during the nasal cycle may support nasal functions such as humidification, respiratory defense, and detecting a broader range of odors.
2
[ "breathe_out_of_one_nostril/Nasal_cycle_3.txt", "breathe_out_of_one_nostril/Nasal_cycle_2.txt" ]
biology-1-a4
Most people normally do not notice the asymmetry, but persistent one‑sided blockage can also result from conditions like allergies or deviated septum.

Humans possess roughly 400 types of olfactory receptors, far more than the three cone photoreceptors underlying RGB-based color vision.
3
[ "RGB_equivalent_for_smells/Olfactory_receptor_0.txt", "biology-2/extraction_8.txt" ]
biology-2-a2
Olfaction uses combinatorial coding: each receptor responds to multiple odorants and each odorant activates multiple receptors, producing pattern-based smell representations.
3
[ "RGB_equivalent_for_smells/Olfactory_receptor_3.txt", "biology-2/extraction_0.txt", "biology-2/extraction_1.txt" ]
biology-2-a3
Because odors arise from complex mixtures and enormous combinatorial possibilities, humans can discriminate extremely many stimuli, estimated around a trillion.
2
[ "biology-2/extraction_4.txt" ]
biology-2-a4
Odor mixtures interact nonlinearly through receptor competition, antagonism, perceptual synthesis, and phenomena like olfactory white, preventing simple RGB-style mixing rules.

Cerebral lateralization is widespread across animals, producing consistent left–right behavioral asymmetries including preferential limb use in many species.
3
[ "animals_handedness/Laterality_2.txt", "biology-3/extraction_3.txt" ]
biology-3-a2
Studies of domestic cats show many individuals consistently favor one paw for tasks, though populations overall show roughly balanced left and right preferences.
3
[ "biology-3/extraction_1.txt", "biology-3/extraction_2.txt" ]
biology-3-a3
Sex-related patterns influence paw preference in cats and other animals, with males tending leftward and females more often showing right-sided bias.
2
[ "animals_handedness/Handedness_7.txt", "biology-3/extraction_0.txt" ]
biology-3-a4
Other species such as dogs and parrots also display limb or foot preferences, sometimes even producing population-level lateralization patterns.
2
[ "biology-3/extraction_4.txt", "biology-3/extraction_5.txt" ]
biology-4-a1
Dichromatic vision can improve detection of camouflaged objects because absence of red–green contrast reduces interference from irrelevant color variation.
3
[ "biology-4/extraction_3.txt" ]
biology-4-a2
Behavioral and field studies show dichromats may outperform trichromats at detecting cryptic prey or camouflaged targets, supporting ecological niche divergence.

Superfecundation occurs when multiple ova released in the same menstrual cycle are fertilized from separate acts of intercourse.
3
[ "twins_with_different_fathers/Superfecundation_0.txt", "biology-5/extraction_6.txt" ]
biology-5-a2
Sperm can survive several days in the female reproductive tract while eggs remain viable briefly, enabling fertilization from different partners.
2
[ "twins_with_different_fathers/Superfecundation_1.txt", "biology-5/extraction_2.txt" ]
biology-5-a3
Heteropaternal superfecundation produces dizygotic twins sharing the same mother but different fathers, making them genetically half‑siblings.
3
[ "twins_with_different_fathers/Superfecundation_2.txt", "twins_with_different_fathers/Twin_9.txt" ]
biology-5-a4
Although rare in humans, documented cases confirmed by genetic testing and paternity studies demonstrate twins can have different fathers.
2
[ "biology-5/extraction_0.txt", "biology-5/extraction_4.txt", "biology-5/extraction_5.txt" ]
biology-6-a1
Natural selection’s strength declines with age because reproductive probability peaks early and falls later, reducing evolutionary pressure on late-life traits.
3
[ "evolution_not_make_our_life_longer/Mutation_accumulation_theory_2.txt", "biology-6/extraction_0.txt", "biology-6/extraction_2.txt" ]
biology-6-a2
Mutation accumulation theory proposes that harmful mutations expressed only in late life persist because carriers already reproduced before effects appear.

Stretching or separating a joint lowers synovial fluid pressure, causing dissolved gases to form bubbles whose rapid formation or bursting produces popping sounds.
3
[ "cracking_joint/Crepitus_1.txt", "biology-7/extraction_3.txt", "biology-7/extraction_5.txt" ]
biology-7-a2
Scientific debate exists whether the cracking sound comes from formation of a gas cavity during separation or collapse of cavitation bubbles.
2
[ "biology-7/extraction_0.txt", "biology-7/extraction_1.txt", "biology-7/extraction_6.txt" ]
biology-7-a3
After cracking, the joint enters a refractory period because gas must re‑dissolve into synovial fluid before another bubble event occurs.
2
[ "cracking_joint/Joint_cracking_0.txt" ]

Coconut flowers typically possess a tricarpellate gynoecium, meaning the ovary forms from three carpels that later contribute to fruit structure.
3
[ "biology-11/extraction_0.txt", "coconut_three_holes/Gynoecium_3.txt" ]
biology-11-a2
During fruit development, the three carpels fuse and shape the coconut endocarp, producing three longitudinal ridges visible on the shell.
3
[ "biology-11/extraction_1.txt", "biology-11/extraction_2.txt" ]
biology-11-a3
Between the three ridges at one end of the coconut shell are three pores or micropyles corresponding to the underlying carpels.
