Given what we know, we can confirm that as scientists study fossil records, they can learn much about the species, such as the traits and activities of the organisms in question.
<h3>What does each fossil type teach us?</h3>
- Trace fossils such as footprints can teach us about the activities of the organisms.
- Meanwhile, scientists will use body fossils to learn about the specific traits of early organisms.
- Body fossils can at times also provide insight as to the diet of the species.
Therefore, we can confirm that scientists will use body fossils to learn more about the traits and diets of early organisms while using the uncovered trace fossils to track the activities of these organisms.

Answer:
It is an example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness.
Explanation:
Natural selection:
The population contains both superior as well as an inferior organism where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
The given question is the example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness. Directional selection will not lead to fixation of cheater genotype. This is because cheating can be controlled through high relatedness in social groups, resulting from kin discrimination.
It is controlled through positive pleiotropy, where the cooperation gene has an additional vital function. Cheating will be controlled if stalk vs. spore is a result of environmental, not genetic factors. An example, spore fate can be a result of the position in the mitotic cell cycle.
If you didn't know already, trisomy 21 is also known as Down Syndrome. It is caused by error in the cell division which is called nondisjunction. It leaves a sperm or egg cell with an extra copy of chromosome 21 before or after conception.
What would most likely occur is that the organisms that eat salmon would have less food to eat and if their food supply, in this case, salmon were to run out, they would die or they would have to find something else to eat. If the organism that eats the salmon dies, in this case we'll call that organism, organism A, any other organisms that eat organism A will die or will have to find another means of food. So basically it causes a disruption in the food chain which can lead to the extinction of different species
