Several fish species became extinct millions of years ago. The graphs provided below show the distribution of fossils of these f
cestrela7 [59]
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.

Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends
Travka [436]

Answer:

Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends  this information through a(n)  <em>sensory</em> neuron to his CNS. A(n) <em>interneuron</em> picks up  this information and carries it to <em>motor neurons of the CNS</em>, which sends a signal to the muscles in his foot causing his  foot to pull away from the rock.

Explanation:

The scenarios discussed in the question is known as a reflex action. In this action, specific receptors detect specific stimuli. For example, pain in the barefoot due to steeping on a sharp rock was the stimuli. This stimulus was detected by the sensory neurons. The sensory neurons turned this information into a chemical signal which was transported by the interneurons to the motor neurons of the CNS. The CNS detected the signal and gave information for a response as a result of which Santi pulled back his feet.
