Answer:
Skin is the human body's largest organ.
Explanation:
Body organs aren't all internal like the brain or the heart. There's one we wear on the outside. Skin is our largest organ—adults carry some 8 pounds (3.6 kilograms) and 22 square feet (2 square meters) of it.
Answer:
interspersed, transposon-derived repeats, simple sequence repeats.
Explanation:
In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.
Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are mobile DNA sequences that can migrate to different regions/areas of the genome.
Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.

Answer:
Explanation:
Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.
