Answer:
Dual distribution
Explanation:
Dual distribution is a method of distribution or arrangement, whereby a company uses majorly two approaches simultaneously in distributing their products to their end-users. The company or manufacturer of the product sells their products directly to the end-users and also sells their product to companies that act as marketing intermediaries that later resell their products to the end-users.
According to the information given in the question above, we can infer that the method of distribution used by pharmaceutical companies is an example of <em>dual distribution.</em>
<span>The use of human cells in research can lead to ethical problems
Because the new use of cells most often lead to this "grey area" in ethics as it is a new area of science and our society is not yet conditioned to this scientific breakthough. As there is no "moral code" on human cell use, ethical objections can arise and led to conflicts.

When looking at the other options they do not cause negative effects on society
1) </span><span>Immortal animal cell lines can be used to model human cells.
----> This technology is not yet developed so it cannot be negative (yet)
2) Organ culture increases the time between donation and transplant.
-----> Organ culture are actualy </span><span>an alternative for organs from donors, and will not increase the time btween donation and transplant</span><span>
3) People are more aware of the results of cell technology research.
</span>-----> Awareness of research lead to greater understanding and unity
Gray cannot blend. Dark rocks let black fur blend in. White sones can blend with white fur. Gray would stick out and then not survive. Population of black and white would go up, and then the gray would go down.
Answer is B.
Overfishing would lead to a bottleneck effect, as large numbers of fish are removed from a fish population. Population size has a major effect on the amount of genetic diversity. The greater the population, the greater genetic diversity. Due to overfishing, the population would become smaller, which would reduce genetic diversity. So the answer is B.
Question:
Which of the following aids in the weathering and transportation of rocks?
A.
wind
B.
clouds
C.
sunlight
D.
all of these
Answer:
Winds aids in the weathering and transportation of rocks
Explanation:
Weathering is process of break down of the rocks, and then it gets dissolved into small pieces by the means of physical, physiological, chemical or also biological process. Transport of these particles helps in the completion of the process, this leads to the movement of the materials from one place to another. Basically the erosion takes place by, water wind and ice. Hence two types of weathering have been reported like mechanical and chemical.
