The correct answer is - Mercator projection map.
The Mercator projection map is a cylindrical type of map that represents the Earth in rectangular manner. While the map may seem as a nice representation of the Earth, and it has accurate directions, it also has some flaws. The biggest flaw of this map is the distortion of the sizes. The distortion is non existent on the Equator, but as it moves north and south of it towards the poles, the distortion is constantly increasing. This projection is not made to be able to cope with the increase of the scale, especially when it it is infinite at the poles.
Because of this, on this map, Greenland looks very similar in size with Africa, even though in reality it is around 15 times smaller.
Answer:
1. Weaker
2. Continuous
Explanation:
A tumor suppressor gene codes for retinoblastoma protein (pRb). The retinoblastoma protein binds to transcription factor E2F when DNA damage is detected. The E2F bound to pRb can not stimulate expression of genes that code for proteins required during the process of DNA synthesis. The cell can not enter the S phase.
On the other hand, when the retinoblastoma protein is phosphorylated by cyclin E-CDK2, E2F transcription factor is free to stimulate the expression of genes required for DNA synthesis and the cell proceeds from G1 to S phase.
When the mutated retinoblastoma gene code for a protein that serves as phosphorylated protein, it will not be able to bind strongly with E2F and there would be continuous expression of genes required for S phase.
