Schwann cells are not component of areolar tissue. The areolar tissues are made up of the matrix, fibroblasts, mast cells, macrophages, reticular fibres, chromatophores, lymphocytes, and plasma cells. Schwann cells (SCs) are the main glial cells of the peripheral nervous system which wrap around axons of motor and sensory neurons to form the myelin sheath.

Anthesis refers to the process of opening of the floral buds. It involves dehiscence of the anthers, attracting the pollinators, stigma receptivity, style elongation etc. Also, anthesis can be a sequential process in the inflorescence. The flower during anthesis becomes functional.

Ribosomes are very fine particles located in the cell fluid of a living cell, which have an important role in the synthesis of proteins. They convert signals from genetic material (DNA or RNA) into the protein chain. They are found on the upper surface of the endoplasmic reticulum, in addition to those found in mitochondria and chloroplasts. tRNA carries amino acid at its 3' end amino acid attachment site.

The dormancy caused by conditions within the embryo itself is called endogenous dormancy. It includes physiological dormancy, morphological dormancy, and combined dormancy, Morphological dormancy is a type of endogenous dormancy. In this, the embryo is underdeveloped or undifferentiated. 

According to the given figure, A⁺ is present in the octahedral void of X⁻. 

The limiting radius in octahedral void is related to the radius of sphere as

The dimension of thermal conductivity is MLT⁻³K⁻¹, expressed in terms of the dimensions mass (M), length (L), time (T), and temperature (Θ). Other dimensions given do not match with the thermal conductivity.

Situated in Gujarat, Rann of Kutch is also known as the Flamingo city. It houses a great number of beautiful pink flamingos. These birds fly here from central Asia after each monsoon to build their nests, breeding in shifts through the winter, and in summer they disappear. It is a major attraction for tourists.

Since excess pressure inside an air bubble of radius  the smaller bubble has higher pressure. Hence air flows from smaller bubble to larger bubble.

The substances which are attracted towards a magnet are called ferro-magnetic materials Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.

From the figure below we can analyze the IUPAC name:

∴ Systematic IUPAC name : 2-Hydroxypropane-1,2,3-tricarboxylic acid.
