Explanation

The telencephalon is the part of the developing brain that eventually forms the cerebral hemispheres.

The term "cerebral hemispheres" is synonymous with the telencephalon. 

Explanation

If a codon consisted of only two nucleotides, there would be 16 possible codons. 

Since there are four possible nucleotides (A, C, G, and T), each position in a two-nucleotide codon could be filled by any of these nucleotides.

Therefore, to calculate the total number of possible codons,

We multiply the number of possibilities for the first position by the number of possibilities for the second position:

4 nucleotides * 4 nucleotides = 16 possible codons. 

Explanation

At room temperature, H₂ (hydrogen) has the lowest density among Ne (neon), N₂ (nitrogen), and CO (carbon monoxide). 

Density is directly proportional to molar mass, meaning the gas with the lowest molar mass will have the lowest density.

Hydrogen has the lowest molar mass among the listed gases, making it the least dense. 

Explanation

In the 3d series of the periodic table, melting and boiling points generally increase up to the middle,

Reaching a peak around elements like Chromium (Cr), and then decreasing towards the end of the series, with Zinc (Zn) having the lowest melting point. 

Explanation

Iodine is solid due to its high polarizability. 

Iodine is a solid at room temperature due to the strong intermolecular forces present between its molecules, specifically London dispersion forces

These forces arise from the large size and high polarizability of iodine atoms.

Larger atoms like iodine have more electrons, which are easier to distort, leading to stronger attractive forces between molecules.

This allows iodine molecules to stick together in a solid state

Explanation

nsulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

Explanation

Kinetic energy (K.E) in terms of momentum is given by the formula:

K.E = p² / (2m)

Where:  

- p is momentum  

- m is mass  

Explanation

Brewster’s angle is the angle of incidence at which light with a particular polarization is perfectly transmitted through a surface with no reflection.

At this angle, the reflected and refracted rays are perpendicular (90° apart).

Explanation

The speed of sound in a gas is proportional to the square root of temperature (in Kelvin):

v ∝ √T

If the temperature becomes 16 times, then:

New speed = √16 × original speed = 4 × original speed

Explanation

 Ferromagnetic materials are those that can retain a permanent magnetization even after an external magnetic field is removed.

This property is due to the aligned magnetic domains within the material.

Iron (Fe), Cobalt (Co), and Nickel (Ni) are all ferromagnetic.

Antimony (Sb), on the other hand, is not ferromagnetic; it is classified as diamagnetic, meaning it repels a magnetic field.
