Master of the Cells B16/B17
This type of nuclear division occurs to replace damaged cells or allow an organism to grow, producing two genetically identical diploid cells.
What is Mitosis?
This biological concept represents a unit containing all of the organisms in a community and their surrounding environment interacting together.
What is an Ecosystem?
his chemical adjective, meaning "without water," describes the blue form of cobalt(II) chloride or the white form of copper(II) sulfate.
What is Anhydrous?
This unique chemical family of salts is consistently produced whenever dilute sulfuric acid successfully neutralizes a basic compound.
What are Sulfates?
This is the term for an organic compound composed entirely and exclusively of hydrogen and carbon atoms.
What is a Hydrocarbon?
These alternative, distinct versions of the exact same gene dictate varied traits like pale grey vs. charcoal chinchilla fur.
What are Alleles?
Human height and weight display this type of variation, characterized by a complete, continuous range of phenotypic data between two extremes.
What is Continuous Variation?
A reversible system can only reach dynamic equilibrium when contained inside this type of isolated, uncompromised vessel.
What is a Closed System?
This is the collective name given to the water molecules trapped and chemically bound inside the crystalline framework of hydrated salts.
What is the Water of Crystallisation?
Alkanes are classified by this term because all of their carbon-to-carbon bonds are composed entirely of single covalent links.
What is Saturated?
This specialized reduction division halves the chromosome count to yield four genetically unique haploid gamete cells.
What is Meiosis?
This is the precise term for an inherited structural or behavioral feature that actively helps an organism to survive and reproduce in its specific habitat.
What is an Adaptive Feature?
This is the identity of the raw material from which industrial manufacturers extract the Nitrogen gas needed for the Haber Process.
What is Air?
This quantitative laboratory technique using a burette, indicator, and pipette must be deployed to prepare a soluble salt when both starting reagents are soluble alkalis and acids.
What is a Titration?
This environmental catalyst or energy source is mandatory to kickstart the substitution reaction between methane and chlorine gas.
What is Ultraviolet (UV) light?
It is the specific cell structure where the sequence of bases in a DNA molecule is read to synthesize a chain of amino acids into proteins.
What is a Ribosome?
This type of selection occurs when humans purposefully choose individual animals or crops with preferred traits to cross-breed across generations.
What is Artificial Selection (or Selective Breeding)?
To speed up the rates of both the forward and backward reactions equally without altering the overall position of equilibrium, factories introduce this metal element into the Haber loop.
What is Iron?
According to general solubility parameters, this specific rule dictates the solubility behavior of all Nitrate salts without exception.
What is that all Nitrates are soluble?
This type of chemical mechanism breaks open an alkene's reactive C=C double bond to integrate new halogen atoms and change orange bromine water colorless.
What is an Addition Reaction?
These unspecialized biological cells are capable of dividing indefinitely by mitosis before transitioning to become highly specialized tissues.
What are Stem Cells?
This phase of a standard population sigmoid growth curve is defined by a stagnant population size where the birth rate perfectly equals the death rate.
What is the Stationary Phase?
These are the exact numerical parameters chosen by chemical engineers for the temperature and operating pressure to run an efficient, economical Haber reaction.
What are 450 degrees C and 20,000 kPa (or 200 atmospheres)?
This precise separation process is used to isolate an insoluble salt like barium sulfate immediately after mixing two soluble ionic solutions together.
What is Precipitation?
This is the definition for compounds—such as but-1-ene and but-2-ene—that hold the exact same molecular formula but display entirely different spatial arrangements.
What are Structural Isomers?
