What Is the Largest Cell in Male Human Body?
The brain and spinal cord are made up of many cells, including neurons and glial cells. Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain. There are many more glial cells; they provide support functions for the neurons, and are far more numerous than neurons.
There are many type of neurons. They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from a fraction of an inch to several feet (purkinjee cell).

Do pupil of human eye have different shapes ?
The pupil is the opening in the center of the iris. The size of the pupil determines the amount of light that enters the eye. The pupil size is controlled by the dilator and sphincter muscles of the iris. The iris has two muscles: The dilator muscle makes the iris smaller and therefore the pupil larger, allowing more light into the eye; the sphincter muscle makes the iris larger and the pupil smaller, allowing less light into the eye.
Pupil size can change from 2 millimeters to 8 millimeters. This means that by changing the size of the pupil, the eye can change the amount of light that enters it by 30 times.
What are the genes on an operon and what does each do ?
OPERON MODEL (Operon Hypothesis)
‘Lac’ operon (a Inducible operon=Genetic induction)
Francois Jacob and Jacques Monod (1961) proposed a model in 1961 of regulating system of gene action in the colon bacillus, Escherichia coli (or E. coli) and named it operon model (or operon hypothesis). They got Nobel prize in 1965 for describing. This hypothesis states that each metabolic reaction is controlled by a set of genes. All the genes controlling metabolic reaction constitute an operon. They studied the catabolism of lactose in E.coli which involves a set of genes. All these genes involved in the catabolism of lactose are called lac operon .
The operon model is formed of two types of genes namely : a. Structural genes (Co-ordinating genes) and b. Control genes.
a. Structural genes : They have the codes for the synthesis of enzymes (proteins) necessary for the metabolic reactions. These are cistrons—Z, Y and X responsible for synthesizing m—RNA and subsequently enzymes and proteins. These genes are found close to each other and are also called cluster genes.
b. Control genes : They control the activity of structural genes. The control genes are three types, namely regulator gene, promotor gene and operator gene.
(a) Promoter gene (P). This is the site where the synthesis of m—RNA is initiated. The RNA polymerase for the synthesis of m—RNA is bound to this gene. This is located adjacent to Z structural gene.
(b) Operator gene (O). This gene controls the initiation process at the promoter gene. It is located close to P.
(c) Regulator gene (R). This gene inhibits or suppresses the functioning of structural genes. It products a protein called repressor, a protein with aminoacids 360 which on combining with the operator site, inhibits the production of m—RNA, and switches off the operon system. The regulator gene is lodged near the operator gene but not immediately adjacent to the latter.

How and why do an egg become rotten ?
The stench associated with rotten eggs is caused by the sulfur compound hydrogen sulfide. The stinky smell emanating from feed lots and barn-yards is one created by the sulfur compound methyl mercaptan. The odour you associate with the ocean is in part due to the presence of dimethyl sulfide. Reasons for egg rotten can be many:
During storage, enzymes generate H2S, NH3and volatile fatty acids.
Once the egg is frozen at – 0.5 C and it becomes unsuitable for further storage. We need to avoid the big differences in temperature during storage, because the egg “sweats,” promoting the proliferation of bacteria.
Sometimes the egg is spoiled during storage. The green rotting (in basic medium) is caused by Pseudomonas species that are penetrated into the egg from faeces. They cause also red rotting (in acidic medium). The yolk becomes black and hard (black rotting), the albumen is evil-smelling upon the effect of Proteus spp. (e.g. vulgaris). Yeasts can also penetrate into the egg during storage. In the fertilized egg, the germ may start developing at low storage temperature of 37-38 oC. Under this condition after a certain time the embryo dies and the blood-ring egg develop that is not good for human consumption.
