Answer:
Clusters of cocci (i.e., grape-like cocci)
Explanation:
Cocci (in singular coccus) are spherical-shaped bacteria, while bacilli and spirilli are rod-shaped and spiral-shaped bacteria, respectively (in general, bacteria can be divided into these three categories by shape). <em>Staphylococcus aureus</em> forms irregular clusters of cocci (i.e., grape-like cocci) when viewed through a microscope. Some Gram-positive cocci include, for example, <em>Staphylococcus aureus</em> and <em>Streptococcus pneumoniae</em>. These species are well known to be bacterial pathogens capable of infecting humans.
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.

Answer:
D
Explanation:
because they have C, H, O, and N but about 500 naturally occurring amino acids are known and can be classified in many ways. But they have all of the answer that you put down I think
63 is your answer hope this helps
The Big Bang theory is a cosmological model for the observable universe from the earliest known periods through its subsequent large-scale evolution.
