The complete question is as follows:
The lethal tumor dose is defined as the dose that will eradicate what percentage of the tumor yet preserve normal tissue?
a) 85%
b) 95%
c) 65%
d) 75%
- Radiation dose is used as a therapy of cancer as the radiation leads to the breakage of the DNA and hence, renders the cell incapable of growth and division.
- Lethal tumor dose is defined as the dose of radiation that is required for the production of complete eradication of tumor.
- The dosage of the radiation depends on the sensitivity of the target tissues to radiation along with the size of the tumor.
- The lethal tumor dose is defined as the dose that will eradicate 95% of the tumor however it would still preserve the normal tissue.
A concentration gradient is a process of particles, which are sometimes called solutes, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles. The areas are separated by a membrane.

Answer:
The correct answer is option C.
Explanation:
The slugs prefer pink flowers over the white ones. Thus, if the slugs are withdrawn from the population, the pink flowers are no more consumed and their number enhances. In a similar manner, the bees like to pollinate more pink flowers in comparison to the white ones.
Thus, again, the pink flowers are getting pollinated in huge concentrations. Thus, the fruits and seeds are set and they produce another generation of pink flowers. Ultimately, there would be more pink flowers in the region in comparison to the white ones as the slugs that used to consume them, are also withdrawn.
Earlier, both the numbers of pink and white flowers would remain steady as even though only some of the bees were pollinating white flowers, they were not getting consumed by the slugs. This had maintained a balance between the number of pink and white flowers. Thus, the number of pink flowers would increase with time if the slugs are removed.
Liver would be the answer. Hope this helps. :)
