Answer:

Question 1

D

Question 2

C

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.)

Which of the following statements about the products of glycolysis is TRUE?
lana66690 [7]
<span>You are likely talking about aerobic respiration rather then just glycolysis based on the options: The third option seems best, pyruvate is heavily oxidized during the Kreb's cycle and removed as CO2.
 
Wrong options
Option1- FADH2 is also another highly energetic molecule produced during

Option2- oxidation of pyruvate is a highly directional process and can be considered irreversible in the cell

Option4- Aerobic respiration RELEASES energy from pyruvate and the into NADH/FADH which is then captured by the electron transport chain. An exergonic rxn would take in energy and would not happen spontaneously


This can be looked from different perspectives, but let me know if my answer made sense. </span>

Which factor most likely caused animals and plants in India to differ greatly from species in nearby southeast Asia?
Dominik [7]

Answer:

India was a separate continent until 45 million years ago

Explanation:

India was part of the Gondwanaland continent which was one of the two remnants of Pangaea, while Asia was part of Laurasia, the other remnant of Pangaea. Because these two land masses were separate, the animals and plants were evolving separately for millions of years. India further separated from Gondwanaland, and it was actually a very large island for millions of years, resulting in isolation and development of unique animals and plants because of it. As India was moving it reached Asia and collided with it, thus becoming one land mass. Some Asian species managed to get in India, but mostly in its northern parts, while the central and southern parts remained dominated by the indigenous species. The Himalayan Mountain Range that formed because of the collision also helped in preserving lot of the indigenous species as it became a natural barrier that most species can not go through.
