Answer:
The most important information in this model he developed is the "filter theory."
Explanation:
Filter theory is a description of desirability planned by Kerchoff and Davies (1962). This concept proposes that individuals advance associations by smearing a sequence of filters, such as resemblance of communal demographic issues and arrogance and complementary of wants to slender down the pool of obtainable candidates. Filter theory is a sociological theory concerning dating and mate selection. It proposes that social structure limits the number of eligible candidates for a mate. Most often, this takes place due to homogamy, as people seek to date and marry only those similar to them.
A carbohydrate composed of two covalently bonded simple sugars is called a <u>disaccharide</u>.
Carbohydrates or sugars are one of the four main categories of the macromolecules that make up living things (the other three being nucleic acids, proteins and lipids). It can either be a simple sugar (sugar monomer or monosaccharide) or a polymer of simple sugars.
Carbohydrates are composed entirely of carbon, oxygen and hydrogen atoms. Simple sugars or monosaccharides contain six carbon atoms, twelve hydrogen atoms and six oxygen atoms. When two monosaccharides bond covalently, they form a disaccharide.
Some examples of disaccharides include:
- Sucrose or table sugar - It is made up of one glucose molecule and one fructose molecule
- Lactose or milk sugar - It is made up of one glucose and one galactose molecule
- Maltose or malt sugar - It is made up of two glucose molecules.

Answer:
Germline mutations
Explanation:
Mutation in the cancer critical genes leads to the formation of stable mutant protein whose accumulation leads to the origin of cancer cells. Mutant p53 proteins not only lose their tumor suppressive activities (P53 gene is a tumor suppressive gene) but often gain additional oncogenic functions that allow for uncontrolled division of cells allowing increased growth and survival advantages. the same also goes for the retinoblastoma gene which is also a tumor suppressor gene that regulates cell division and other cellular activities. This mutations are usually inherited and can be transfered to their offspring.
Answer:
IT IS BEST FOR A CELL TO HAVE A LARGE SURFACE AREA AND A SMALL VOLUME. THEREFORE, A LARGE SURFACE AREA TO VOLUME RATIO IS MORE DESIRABLE.
