When multiple glaciers start their downward flow from a single point, they create an avalanche. It is a rapid flow of snow down a sloping surface. Hope this answers the question. Have a nice day. Feel free to ask more questions.<span>

The correct answer is: Eubacteria.
The human microbiota is the name for all of the bacteria found within the human body. This aggregates of microorganisms are wide spread in different tissues, such as the skin, mammary glands, seminal fluid, uterus, saliva, oral mucosa, conjunctiva, gastrointestinal tracts.
Without undergoing any changes itself, the enzyme makes changes to the substrate.
<h3>What is an enzyme?</h3>
An enzyme is a biological catalyst that acts by lowering the activation energy in a chemical reaction.
In a chemical reaction, an enzyme binds to a substrate to convert it to one or more products.
In conclusion, without undergoing any changes itself, the enzyme makes changes to the substrate.

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.
