Important topics for neet with high weightage of physics class 12

Image
Here are some key notes for Physics of class 12 that can be useful for preparing for NEET UG: Electrostatics : Coulomb's law, electric field, electric potential, capacitance, and dielectrics. Current Electricity : Ohm's law, Kirchhoff's laws, and electromagnetic induction. Magnetic Effects of Electric Current : Biot-Savart law, Ampere's law, and electromagnetic waves. Optics : Reflection, refraction, and lenses, including Snell's law, and optical instruments like the microscope and telescope. Dual Nature of Matter and Radiations : Photoelectric effect, wave-particle duality, and the Uncertainty principle. Atoms and Nuclei : Atomic structure, isotopes, and radioactivity. Electronic Devices: Semiconductors and their applications in devices such as diodes and transistors. Communication Systems : Electromagnetic waves and their use in communication systems such as AM and FM radio. It is important to practice solving numerical problems and previous years question papers...

What happens when you mix oil and vinegar? What would happen if you mixed water with both of them at the same time?

Image
  When you mix oil and vinegar, they do not mix well together because oil and vinegar have different densities and are not miscible, meaning they do not dissolve in each other. The oil will form droplets in the vinegar and separate out due to their different densities. This is why dressing made with oil and vinegar often require shaking or stirring to combine the ingredients before use. If you mix water with both oil and vinegar, the oil will still separate from the vinegar and form droplets in the water. The water will not mix with the oil, but will mix with the vinegar to form a homogeneous mixture. This is because vinegar is an aqueous solution (i.e., a solution in water) while oil is not.

DNA Replication notes

Image
  DNA 🧬  replication is a Vital  process that occurs in all living organisms. It is the process by which a cell duplicates its genetic material, creating an identical copy of itself. This process is essential for the growth and reproduction of cells, and it plays a crucial role in the continuation of life on Earth. The process of DNA replication begins with the unwinding of the double helix structure of DNA. This is accomplished by enzymes called helicases, which break the hydrogen bonds holding the two strands of DNA together. Next, enzymes called primases add a short RNA primer to the exposed single strands of DNA. These primers serve as a starting point for the replication process. After the primers are added, enzymes called DNA polymerases bind to the single strands of DNA and begin adding nucleotides, the building blocks of DNA, to the exposed strands. DNA polymerases can only add nucleotides to the 3' end of a strand, so replication proceeds in the 5' to 3' directi...
