Question 3
D
Explanation:
1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.
Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)
2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.
A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)
3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.
Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)
Foodborne illness is the contamination that results from the spread of bacteria from meat to vegetable. Various types of pathogenic micro-organisms get access to food, which is rich in nutrients and allows bacteria to flourish. When such contaminated foods are eaten, they cause foodborne illness.
5 is adaptation, 7 is transpiration
The correct answer is C. To block UV radiation. Ozone filters the majority of UV spectra, so it protects organisms from its effects.
It is possible to predict that because of the decreased number of cone cells, cats have poor color vision.
<h3>What are cone cells?</h3>
Cone cells are specialized cells in the eye required to produce the spectra of color observed in nature.
Cone cells can be considered photoreceptors located in the retina of the eye (in animals and humans).
Cone cells act in the best way in bright light conditions, conversely to rod cells that serve to observe at the night.
