Answer:
See explanation
Explanation:
In a situation whereby a plant is in an environment where light is not totally absent, the plant continues to photosynthesize at a slower rate.
Recall that photosynthesis is the process by which green plants make their own food in the presence of sunlight, chlorophyll, carbon dioxide and water.
In a low light, plants are forced to stretch towards the low light source. This is known as etiolation of plants.
A lake is so deep that light cannot reach all the way to the bottom, so the photosynthesis occurs in the top layers. A pond can have rooted plants, because light reaches down to the very bottom.
Answer:
Option C
Explanation:
Complete Question
Which of the following situations would pose a major difficulty for applying the biological species concept?
a) Two populations of sexually reproducing plants that can be bred easily in the same location under field conditions
b) Two populations of sexually reproducing insects that can be bred easily in the same location under field conditions
c) Five snail fossils taken from the same locality during a 400,000-year time span
d) Dimorphic mating pairs of birds
e) Monomorphic mating pairs of birds
Solution -
According to the biological species concept, two or more organisms that look alike does not mean that they belong to the same species. In order to consider that two organisms belong to the same species, it is essential for them to be able to interbreed or mate.
For example –
Western meadowlarks and Eastern meadowlarks look identical to one another but they do not interbreed with each other and hence they belong to different species.
Hence, option C is correct
The answer is in the image attached.
