Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.
Explanation:
Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc
From the examples given, the cells of multicellular organisms are specialized in function in that:
- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces
On the other hand, unicellular organisms possess just one cell that do all the functions.
Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.
Answer:
I think that the answers are A and D.
For option A, we can come to the conclusion by thinking about the effects of invasive species. For example, when an invasive species appears in a specific environment and unfortunately feed on the same kind of plant as the native species, it will lead to the fact that they have to compete more in order to survive.
For option B, we can clearly see that it's wrong. From the point above, we can also predict that there is a high chance the invasive species will win the competition, resulting in the decrease population of the native specices that couldn't compete.
For option C, it is also impossible, instead the opposite is more likely to happen, because as we know, the native species, after a long period of evolution, became almost perfectly adapted to the environment, the appearance of invasive species may help the diseases that the native species weren't immune to spread faster, decreasing the population.
And I guess option D is obviously correct, no need to explain.
