Answer:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
1. Explain why the distribution of fossils in Figure 1 supports the hypothesis that the extinction of these species was the result of a sudden environmental change.
This hypothesis can be supported because all the fossils accumulate almost at the same age of the rock layer. That is, all the fossils died almost at the same time.
2. Describe an environmental change that could have produced this type of fossil distribution.
Good examples of sudden environmental changes are volcanoes. When a rash occurs, the whole environment suddenly changes for different reasons such as ash or lava, and all living things can die immediately or in a few years by the change in the ecosystem.
3. Explain why the distribution of fossils in Figure 2 supports the hypothesis that the extinction of these species was the result of a gradual environmental change.
This is because the fossils accumulate at different ages of the rock layer, that means, the species dying over time. The gradual descent of the fossils is observed.
4. Describe an environmental change that could produce this type of fossil distribution.
For example, if a climate change occurs - the temperature increases or decreases - it can cause the trees or plants to die and all the animals in the ecosystem also die when they have no food. But this process is sequential, so the change can take years, centuries or even millions of years.
I hope this can help you.
They are semi-permeable because they can diffuse and pass through the plasma membrane easily.
Answer:
The comparatively fast evolution of various species from a single common ancestor is known as adaptive radiation. It usually takes place when an organism enters a novel region and distinct traits influence its survival. The island chain offers suitable conditions for adaptive radiation to take place as when an organism of a certain species comes to an island together and get disperse all through the chain, and each of these organisms getting settle into distinct niches and exploiting various food resources in order to minimize the competition, thus, resulting into adaptive radiation.
