Chemistry / biology /physics applications

[hassam]

this thread is solely for application topics.I could not see any help for application in other threads and since application topics are TOUGH with lot of intensive learning material it is important THAT application topics be considered ESPECIALLY.
U can ask related past paper questions also or if u cant understand the underlying chemistry/physics/biology behind a particular topic....ask here.....and plxx nthing else than application cos those other threads are working very good!!!
some SUPPORT MATERIAL for application

Cystic fibrosis is an autosomal recessive disease in which
thick mucus is produced in the lungs and airways. The gene
responsible for this disease codes for a protein composed of
1,480 amino acids. In most patients with cystic fibrosis, the
protein has 1,479 amino acids: A phenylalanine is missing at
position 508. A baby is born with cystic fibrosis. He has an
older brother. How would you test the DNA of the brother to
determine if he is a carrier for cystic fibrosis? How would you
design a gene therapy protocol to “cure” the cells in the lung
and airway?

What is a CT scan?​

A computerized axial tomography scan is an x-ray procedure that combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body. Computerized axial tomography is more commonly known by its abbreviated names, CT scan or CAT scan. A CT scan is used to define normal and abnormal structures in the body and/or assist in procedures by helping to accurately guide the placement of instruments or treatments.​

A large donut-shaped x-ray machine takes x-ray images at many different angles around the body. These images are processed by a computer to produce cross-sectional pictures of the body. In each of these pictures the body is seen as an x-ray "slice" of the body, which is recorded on a film. This recorded image is called a tomogram. "Computerized Axial Tomography" refers to the recorded tomogram "sections" at different levels of the body.​

Imagine the body as a loaf of bread and you are looking at one end of the loaf. As you remove each slice of bread, you can see the entire surface of that slice from the crust to the center. The body is seen on CT scan slices in a similar fashion from the skin to the central part of the body being examined. When these levels are further "added" together, a three-dimensional picture of an organ or abnormal body structure can be obtained.​

solve this problem

As-salam-o-alaikum!

Is this related to the first topic?
cuz i only did that! I don't seem to understand it!

Assalamoalaikum!!

Thank you so much for these......

but I feel the application booklet states some things wrongly?! is it?

and thanks...these videos helped me understand the process....Jazak Allah Khairen!

and do u have the new application booklet for biology...is it even there? cuz there are new ones for physics and chemistry?!

 

[hassam]

yea application booklet is confusing......i m waching video and then trying to link the process decribed in video with points in revision guide and booklet
