Chemistry
What is the electronic configuration of the most stable oxidation state of the element Ruthenium?
+3
What is the difference between elastic and inelastic collisions in mechanics?
In a elastic collision, the total kinetic energy remains conserved, whereas, in an inelastic collision, the total kinetic energy at the starting and ending of the collision is different.
What is the function of a ribosome and what are the two main subunits that make up a ribosome in molecular biology?
Ribosomes are used to create proteins. Two main subunits of Ribosoms are the small subunit, and the large subunit.
What is the difference between a rock and a mineral, and how do geologists determine the properties of each?
Minerals are naturally formed, while Rocks are made from Minerals, determined by looking at physical features.
What is the significance of the discovery of the "Lucy" fossil in the field of anthropology?
It revealed that bipedalism, it seems, was the first step towards becoming human.
What is the mechanism of the reaction between an aldehyde and a primary amine to form an imine?
A nucleophilic addition-elimination reaction.
What is the relationship between entropy and the second law of thermodynamics in a spontaneous process?
What is the difference between a prokaryotic and eukaryotic cell and how does this difference impact the structure and function of the cell?
Eukaryotic cells contain membrane-bound organelles, while prokaryotic cells don't. The presence of membrane-bound organelles in eukaryotic cells allows for compartmentalization of different cellular processes.
What is the cause of lightning?
In the initial stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground; however, when the differences in charges become too great, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning.

What is the difference between monetary policy and fiscal policy?
Monetary policy refers to central bank activities that influence the quantity of money and credit in an economy. By contrast, fiscal policy refers to the government's decisions about taxation and spending
What is the difference between atomic absorption spectroscopy and atomic emission spectroscopy?
Atomic emission spectroscopy measures the intensity of light emitted by the excited atoms, while atomic absorption spectroscopy measures the light absorbed by atomic absorption.
What is the relationship between electric fields and magnetic fields in electromagnetic waves?
In electromagnetic waves, electric and magnetic fields are intertwined and mutually dependent
What is the difference between a genotype and a phenotype?
Genotype refers to the alleles you possess for a particular gene or set of genes. Phenotype is the physical trait itself, which may be influenced by genotypes.
What is the difference between a thermocline and a halocline?
A thermocline is an area within a body of water that marks a drastic temperature change. A halocline is a relatively sharp discontinuity in ocean salinity at a particular depth.
What is the difference between a presidential system of government and a parliamentary system of government? What is the difference between a presidential system of government and a parliamentary system of government?
The presidential system elects a head of government independently of the legislature, while in contrast, the head of government in a parliamentary system answers directly to the legislature.
What is the role of chaperones in protein folding, and how do they prevent misfolding and aggregation?
Chaperones assisting protein folding in the cell under physiological and stress conditions. They translate ribosomes to bind and stabilize nascent polypeptides and promote proper folding.
What is the difference between a coherent and incoherent light source in optics?
A coherent light source has in-phase waves while an incoherent light source has randomly out-of-phase waves.
What is the relationship between biodiversity and ecosystem functioning?
Higher levels of biodiversity lead to greater ecosystem stability and sustainability
What is dark matter, and what evidence do astronomers have to support its existence?
Dark Matter is a substance that is not known to interact with the magnetic force. The founding existence of Dark Matter is the fact that the outer rings of Galaxies spun too fast.
What is the relationship between nature and nurture in the development of personality?
It's complex and dynamic.
What is the fundamental difference between the thermodynamic definition of entropy and the statistical definition of entropy in physical chemistry?
The thermodynamic definition of entropy provides the experimental verification of entropy, while the statistical definition of entropy extends the concept, providing an explanation and a deeper understanding of its nature.
What is the Heisenberg uncertainty principle in quantum mechanics?
The Heisenberg uncertainty principle in quantum mechanics states that there is a fundamental limit to the precision with which we can simultaneously measure the position and momentum of a particle.
What was the exact nature of the first living organism?
There is no definite answer, as research is still ongoing.
What is the impact of ocean acidification on marine ecosystems?
It'll harm life forms that rely on carbonate-based shells and skeletons, harm organisms sensitive to acidity, and harm organisms higher up the food chain that feed on these sensitive organisms.
What is the conflict theory in sociology?
The conflict theory is a sociological perspective that views society as a constantly changing arena of competition and conflict between groups with conflicting interests, values, and goals.
