Botany
This sticky structure is responsible for capturing pollen in the carpels of flowers but can also refer to a mark of disgrace associated with something.
What is a stigma?
This hormone predominates & stimulates uterine lining growth in the second half of the uterine cycle.
What is progesterone ?
This is a species interaction observed in how orchids grow on tree trunks for support and access to sunlight, but the tree does not receive direct benefit or harm from the presence of the orchid.
What is commensalism?
This Swedish naturalist classified thousands of organisms throughout his life and is known as the father of taxonomy.
Who is Carolus Linnaeus?
A food preservation method where food is heated to high temperatures in short amounts of time to kill pathogenic microbes.
What is pasteurization?
In this type of seed germination, cotyledons rise above the soil surface appropriately sharing its prefix with the theme of this year's BioLOGIC!
What is epigeal germination?
In the digestive system, chief cells secrete a precursor substance that can be activated by secretions from the parietal cells. This activated substance performs this function in digestion.
What is proteolysis?
This shallow coastal marine ecosystem, dominated by salt-tolerant trees, serves as a nursery and breeding ground for fish and other marine organisms.
What are mangrove forests?
Gnetophytes are a group of species classified under the paraphyletic grouping "gymnosperms." However, biologists have found out that some gnetophytes like Ephedra and Gnetum can also undergo double fertilization, a unique trait among angiosperms. This evolutionary process can explain this similiarity.
What is convergent evolution?
This polymer, which makes up most of the cell wall of most bacteria, makes up about 90% of gram-positive bacterial cell walls and only 10% of gram-negative ones.
What is peptidoglycan
These cells, which are found in plants that share its name with a type of explosive, surround the vascular bundles and aid in surviving hot and dry environments.
What are bundle sheath cells?
These are a clade of animals in Class Mammalia united by hornlike dermal tissue that is comparable to a human fingernail, which extends over the end of a broadened terminal digit.
What are ungulates ?
This is the process by which genetic variation is gradually lost in small, isolated populations due to chance events rather than natural selection.
What is genetic drift?
Mammals and amphibians are both quadrupeds possessing four limbs. Despite the divergence in their evolutionary paths, it is believed that they once shared a common ancestor that had this condition. This shared characteristic among two or more lineages is an example of this taxonomic trait.
What is synapomorphy/symplesiomorphy?
Viruses use capsid shells and envelopes to infect cells with their RNA or DNA genome. This is the complete inert virus particles found outside of the host cell.
What are virions?
After a megaspore mother cell produces four megaspores by meiosis, only one survives and divides mitotically to form this pouch-like female gametophyte of flowering plants.
What is the embryo sac?
This is the type of symmetry displayed by adult echinoderms such as starfish. Be highly specific.
What is pentamerous radial symmetry ?
A researcher studies a lake ecosystem contaminated with a persistent pesticide. They measure contaminant levels in algae, then in small invertebrates that feed on the algae, then in fish that eat the invertebrates, and finally in birds that feed on the fish. They observe that the concentration of the pesticide increases at each successive trophic level. This process is called...
What is biomagnification?
This modern geological principle states that slow, gradual process such as erosion and sedimentation have shaped the Earth today. A common quote associated with this concept is "the present is the key to the past."
What is Uniformitarianism?
This bacterial appendage, shorter and more numerous than flagella, facilitates adhesion to host tissues or surfaces, which is an essential step in colonization and pathogenesis. Identify this structure.
What are fimbriae?
Two molecules of this organic compound produced during the Calvin cycle are directly used to synthesize one molecule of glucose. Abbreviations are allowed.
What is G3P / Glyceraldehyde-3-phosphate ?
This subfield of zoology focuses on the microscopic anatomy of animal tissues, examining the organization and specialization of cells that collectively perform specific functions, bridging the gap between gross anatomy and cellular biology.
What is histology?
The evolutionary hypothesis first proposed in 1973 which states that species must constantly adapt, evolve, and proliferate to survive while being pitted against an ever-evolving opposing species to "stay in the same place."
What is the "Red Queen Hypothesis"?
A group of vertebrates characterized by a single opening behind their eye socket, which includes all mammals and their direct reptilian ancestors.
What are Synapsida / Synapsids?
This compound with a tongue-twisting name, which shares its acronym to a nickname of Vietnam, is an important component of the bacterial cell wall.
What is N-acetylmuramic acid (NAM)?
