How are stars formed?
Stars form by the slow contraction under gravity of a very large cloud of gas and dust particles in space.

What is a pulsar?
Pulsars are highly magnetized, rapidly rotating neutron stars formed from the remnants of massive stars that have undergone supernova explosions. / Pulsars emit beams of electromagnetic radiation along their magnetic poles, which sweep across space as the neutron star rotates, observed as periodic pulses of light when these beams intersect Earth's line of sight.
What is the most searched question on Google?

Explain what causes the seasons on earth.
Different parts of the Earth receive varying amounts of sunlight at different times of the year. / As Earth moves along its orbit, different parts of the planet are tilted towards or away from the Sun at different times of the year. [1]
When a hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer, while the opposite hemisphere is tilted away from the Sun, receiving less direct sunlight and experiencing winter. [1]
As Earth orbits the Sun, the orientation of its axis remains fixed relative to the stars. [1]
What is the main growth tissue in stems and roots of most plants?
Vascular cambium
How many countries are part of the Paris Agreement?

who is the 5th richest person in the world?
Describe DNA Replication.
DNA replication begins at the origin of replication. Helicase unwinds the double helix structure by breaking the hydrogen bonds between the complementary base pairs in the parental strand. [1]
Each parental strand acts as a template for the synthesis of a new daughter strand. Primase attaches itself to the unwound strand and catalyses the synthesis of RNA primers which help to provide free 3’OH ends for DNA polymerase III. [1]
DNA polymerase III then catalyses phosphodiester bonds between the free incoming deoxyribonucleotides and free 3 ‘OH ends, lengthening the daughter strand in the 5’ to 3’ direction. Daughter strand links itself to the parental strand by complementary base pairing, with A to T and G to C. [1]
Leading strand is synthesised continuously while lagging strand is synthesised discontinuously, forming Okazaki fragments. [1]
RNA primers are removed and replaced by deoxyribonucleotides by DNA Polymerase I. Nicks between Okazaki fragments are filled by DNA ligase through forming phosphodiester bonds. [1]
How does the concept of continental drift start?
The concept of continental drift posits that Earth's continents were once part of a single supercontinent called Pangaea, which gradually broke apart and drifted to their current positions. [1]
What planets show signs of possible life?
Mars, Europa, Enceladus, Titan, Mar’s Moons - Phobos and Deimos, Exoplanets
What is Pauli’s Exclusion Principle?
2 electrons occupying the same orbital must have different spins (they cannot have the same quantum state at the same time)
What is the term for the fear of the number 13?
Triskaidekaphobia
Describe the effect of light energy in light-dependent reactions.
Light energy absorbed by chloroplast pigments in the grana of the chloroplast, for photolysis of water & formation of NADPH & ATP molecules
Light energy is harnessed to split water molecules to form hydrogen & oxygen atoms, yielding O2 as by-product
NADPH & ATP molecules used to drive reactions of light independent stage to synthesize complex organic compounds
