The mono- clonal antibody that forms Herceptin was isolated by inoculating mice with cells expressing excess levels of human HER2 protein, followed by immunization of the murine antibody.

A DNA probe from the human HER2 gene was then used to discover HER2 gene amplification in human breast cancer. The process is known as recombinant DNA technique .

HER2 plays an important role in the signaling network that drives cell proliferation. Herceptin is believed to block intracellular signaling pathways. By attenuating the signal transduction downstream, Herceptin may promote apoptosis and arrest cell proliferation. Herceptin is the brand name of a medicine called trastuzumab. some common uses of Herceptin are they are used in treatment of breast cancer, esophageal cancer and stomach cancer.

Planet X
Explanation:
The orbital radii of planet X is the smallest which means that is closest to the sun. The distance to the star determines the temperature of the planet. Closer the planet, more likely it would have higher temperature. So planet X has highest temperature most likely.
In the solar system, there is exception, mercury is closest to sun but Venus which is the second planet from the sun has highest temperature. This is because mercury has no atmosphere and Venus has very thick atmosphere which traps the solar radiation and heats up.

The answer would be survival of the fittest.

This metaphor, "<em>survival of the fittest</em>," was used by Herbert Spencer to explain <em>natural selection. </em>It is sometimes also referred to as the survival for existence. This phrase came from the Dawinian theory of evolution where he explains that all species are capable of producing many offsprings. However, the survival of those offsprings depends on their ability to adapt to the risks and opportunities of the external environment. 
<em>
</em>This relates to your scenario in the sense that fish lay a lot of eggs in the beginning but not all of them would live to achieve maturity. This is because even as eggs, they have many predators and are exposed to other elements. The threat pushes on even if they are able to hatch and grow up.
