About
You can say, we are one bunch of 41 cheerful, bubbly people who study a common combination of triple Science, Double Math and elective Geography.
Our class is led by two superb ladies-
Classperson, Aini and
Vice-Chairperson, Jasmine; not forgetting our
Welfare Officer, Winanto.
Like every other classes, our class consists of leaders of every club you can think of, ranging from Student Council to Performing Arts to Uniformed Groups!
Thankfully, we have all stepped down from our responsibilities and all sprinting towards our common nemesis, the GCE O Level Examinations.
In general, we are nice
TTM.

Title:
Go Bonkers over Biology
Hey y'all, I came across these while revising for Biology today. Nope, it's not in the syllabus but it's cool to know these. Enjoy.
RetinoblasmaRetinoblastoma (Rb) is a rapidly developing cancer which develops in the cells of the retina, the light detecting tissue of the eye
There are two forms of the disease; a genetic heritable form and a non-genetic non-heritable form
The most common and obvious sign of retinoblastoma is an abnormal appearance of the pupil, leukocoria. Other less common and less specific signs and symptoms are: deterioration of vision, a red and irritated eye, faltering growth or delayed development. Some children with retinoblastoma can develop a squint.
In children with the heritable genetic form of retinoblastoma there is a mutation on chromosome 13, called the RB1 gene.
The genetic codes found in chromosomes control the way in which cells grow and develop within the body. If a portion of the code is missing or altered (mutation) a cancer may develop.
The defective RB1 gene can be inherited from either parent, however in some children, the mutation occurs in the early stages of fetal development. It is not known what causes the gene abnormality; it is most likely to be a random mistake during the copy process which occurs when a cell divides.
Gene TherapyGene therapy is the insertion of genes into an individual's cells and tissues to treat a disease, such as a hereditary disease in which a deleterious mutant allele is replaced with a functional one.
PencillionPenicillin (sometimes abbreviated PCN or pen) is a group of antibiotics derived from Penicillium fungi. Penicillin antibiotics are historically significant because they were the first drugs that were effective against many previously serious diseases such as tuberculosis, syphilis, and staphylococcus infections. Penicillins are still widely used today, though many types of bacteria are now resistant.
Protoplast VS SpheroplastA protoplast is a plant, bacterial or fungal cell that had its cell wall completely or partially removed using either mechanical or enzymatic means.
Protoplasts - Have their cell wall entirely removed
Spheroplasts - Have their cell wall only partially removed.
More generally protoplast refers to that unit of biology which is composed of a cell's nucleus and the surrounding protoplasmic materials.
