Answer: In addition to slowing the overall expansion, gravity causes local clumping of matter into stars and galaxies. ... Within the Local Group, the gravitational interactions have changed the inertial patterns of objects such that there is no cosmological expansion taking place.
Explanation:
Answer:
In this case, the question asked is "To what lengths must we go to protect plants and animals?", which is not specific and cannot be used for scientific research.
The ecological researches for the safety of the environment involves the protection of the plants and the animals on the basis of their number and vulnerability to extinction. Almost all the length of the plants are ecologically important and can decrease in number due to the changes in the environment, the length is not a parameter to determine the protection boundary.

Answer:
Tuberculosis.
Explanation:
it is caused by a bacterium which can attack any part of the body such as the kidney, spine, and brain. not everyone infected with TB becomes sick
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.
