Answer:

Permafrost, amber and tar

Explanation:

Fossils are the remains of prehistoric plants or animals embedded and  preserved in rocks. They are preserved by three main methods: unaltered soft or hard parts, altered hard parts, and trace fossil.

Soft-tissue original remains are very rare except as captured in amber, trapped in tar, dried out or frozen in permafrost.

Amber is ancient tree sap that can trap flowers, worms, insects as well as small amphibians and mammals and preserve them whole.

Permafrost is an area of land that is permanently frozen below the surface. It is common in Siberia (part of Russia) and in Alaska. Many different kinds of frozen extinct as well extant animals have been found in Siberian permafrost, including woolly mammoths, horses and bison, and lions.

Tar or asphalt is a liquid found naturally in small pits in swamps. These pits are  formed from crude oil seeping through the ground. The lighter elements of crude oil evaporate leaving thick sticky asphalt. Animals that fall into these pits hardly escape and their bodies are preserved within. Fossils of animals such as wolves, short-faced bears, American lions, ground sloth and saber-toothed cat have been found preserved intact in tar.

14. Brainstorm and write at least 3 potential challenges or important points to consider when conducting the described
Afina-wow [57]

When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.    

In the exposed example, Pincky is lacking <em>theoretical framework, d</em><em>efining which are the </em><em>study groups, methodology </em><em>to collect data</em><em>, </em><em>and a description of </em><em>data analysis</em>.

---------------------

The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: <em>reproducibility, </em><em>which is the capability of reproducing the experiment in any other place by any researcher</em>, and <em>refutability, </em><em>which is the susceptibility to be refused.</em>

When conducting an experiment, you need to consider,

• Definition and problem statement. The question for which there is not an answer yet.

• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.

• Data collection and analysis. This step involves testing the observations.

• Results

• Verification of hypothesis. This step involves the deriving of the working hypothesis.

• Discussion and Conclusion.

Previous knowledge about the study object is always required for a better understandig.  A question the investigator wants to answer. The main goal of the study, which is basically what the investigator wants to find out. The researcher makes a hypothesis to predict what is going to happen. The experiment is to be performed to answer the question. The conclusions through which the hypothesis might be rejected or accepted.

--------------

So in this experiment there must be,

Theoretical framework, such as information about the species, life stage at which they begin chirping, about external factors that might affect it or benefit it, and etcetera.

The goal: To know how temperature affects cricket´s chirping

Hypothesis: Crickets chirp less frequently under cold temperature than under warm temperature.

Variables: Temperature → Independent

                 Chirp frequency → Dependent

                 Water and food supply, light exposure, refuge → Controlled

Study groups: group of crickets exposed to a warmer temperature

                        group of crickets exposed to a colder temperature

Methodology: Individuals analyzed should be in the same development stage, or at least be sexually mature. Two groups of 10 individuals each should be placed under the same conditions, excepting for temperature. One of the groups should be exposed to warmer temperatures and the other one to lower temperatures. Chirps should be recorded for a week.

Data analysis: Using the chirps records, the frequency can be measured for each group. Results should be compared using different statistical analyses.

Results: Results should be clearly exposed, using texts, charts, and graphs.

Discussion and Conclusion: Hypothesis acceptance or rejection. Discussion about the expected results against the observed ones.

Species can vary in several ways. Which of the following is one of Darwin's ideas that was accepted by most scientists of his ti
fenix001 [56]

Answer:

Due to the large number of fossils being discovered at that time Darwin proposed that species change over long periods of time.

Explanation:

The theory of Darwin was that the species change in accordance to their environment, thus they develop advantageous traits so that they can be more competitive.
