Good Luck!
Answer:
They were competing for the same type of food.
Explanation:
The introduction of brown and black European rats may have led to the extinction of Darwin’s rice rat due to competition for food and resources. These are the main factors that affects am organisms survival.
The brown and black rat were better adapted for survival and competition of the food and resources available which lead to the death and extinction of Darwin’s rice rat.
Answer:
The change of fur color within the population over time became black as a result of the lava flow and allowed the mice to survive.
Explanation:
Because the mice that have brown fur would stand out and get picked of by predators so over time the mice with the darker fur could hide more easy and spread there genetics more easily.
The third option from top is the answer. The major products that result from the Krebs cycle are NADH, FADH and ATP in that order.
The Krebs cycle is the central metabolic pathway in all aerobic organisms. The cycle is a series of eight reactions that occur in the mitochondrion. These reactions take a two carbon molecule called acetate and completely oxidize it to carbon dioxide.
The Krebs cycle serves two main purposes namely:
1.To increase the cell's ATP producing potential by generating reduced electron carriers such as NADH and reduced ubiquinone.
2. To provide the cell with a variety of metabolic precursors.
By the time the eight reactions in Krebs cycle are over, one ATP, one FADH and four NADH molecules will have been produced
