Answer:

This is what I would say:

Hello, today I will talk to you about invasive species and why they should be stopped, invasive species are bad for the environment because they destroy other creatures, like if the native species think that it's prey and decide to eat it; it might harm them. For example, if there were trees in a certain environment and an invasive species came along every creature would get hurt because those trees are very tall and they stop sunlight from reaching the ground so that would help to stop invasive plants from growing but if an invasive species of beetles came along they would eat the trees and kill them making sunlight reach the ground. Then it would help the invasive plants to grow, and what would the invasive species of plants do you ask? They would harm the creatures because there are herbivores and they eat plants and since they might think that the plant is toxic because they look like a toxic plant in that environment they will starve and die. Little by little the animals would get harmed because predators eat the herbivores and if there's no food for them they will die, so you see a lot of creatures would get harmed if we don't stop invasive species.

P.S. maybe you should change the words a little because I used this in previous work.

Ksju [112]
The correct option is this: A STUDY BY DR BIRDIE SHOWED THAT THE NUMBER OF SONGBIRDS IN HER YARD INCREASED DUE TO A MODIFIED FOOD SOURCE.
A scientific claim refers to a claim that is made by a scientist due to the result that he or she obtained in the research that are conducted. In the excerpt given above, it can be seen that Dr Birdie experience influx of songbirds to her yard as a result of the dried apple and the raising that she added to the birds' food.

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.
