Answer:

Develop a hypothesis

Explanation:

Scientific investigations usually begin with observations these are typically something that would catch the researcher’s attention.

<em>1.</em> for example, <em>noticing that all the animals along a stream or water source are ill .</em>

2. The scientist ran attempts to understand what’s causing the problem after formulating or asking a question

  • <em>What’s making them ill?</em>

3. Then, the scientist comes up with a hypothesis which is a testable explanation for the phenomenon or what’s occurring

  • <em>Maybe the water is contaminated </em>

<em />

4. A prediction of the outcome is usually made based on the hypothesis

  • If I give the animals different water they’ll regain their health

5...after which it is tested via an experiment.

  • <em>Replace the water sources and observe </em>

6.  The scientist then use the results to make new hypotheses or predict certain outcomes.

  • <em>Hypothesis supported: animals regain health</em>
  • <em>Hypothesis not supported: maybe it’s the food?</em>

<em />

<em />

<h3>Based on the outcome the scientist may repeat the process which is a normal part of these steps. The scientific method explored above is very repetitive.</h3>

Tcecarenko [31]

<u>Answer</u>: A) Africa and South America only

As shown in the map, the fossil evidence suggests that Cynognathus lived on the modern day continents of South America and Africa. Thus, from this distribution and the fragmentation of the ancient landmass into today's continents, result in the distribution of Cynognathus offspring species also only within the continents of Africa and South America.
