14. Brainstorm and write at least 3 potential challenges or important points to consider when conducting the described
data collection.
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 theoretical framework, defining which are the study groups, methodology to collect data, and a description of data analysis.
---------------------
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: reproducibility, which is the capability of reproducing the experiment in any other place by any researcher, and refutability, which is the susceptibility to be refused.
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.

7. To test a new voice feature in a cockpit design a flight simulator was used. The simulator was programmed to
give visual readings of flight information, or to give visual and auditory (voice) readings of flight information. All
test pilots were put through a simulated emergency landing procedure, but were randomly assigned to the
visual, or visual and auditory conditions. Flight experts rated each pilot's performance in the simulator on a
scale of 1 (very poor) to 10 (excellent).
The variables in the simulation procedure carried out are :
Independent variable = Simulator Independent variable = Simulator Dependent variable = PerformanceThe dependent and independent variables are critical in any experimental study as both variables encompasses the variable to be measured and the variables manipulated in other to obtain the variable to be measured.
Independent variable : This is also called the predictor variable which is tweaked in other to obtain changes in the measured or dependent variable. In the experiment performed, the simulator is the independent variable has it has different visual or visual and auditory conditions capable of causing changes to the performance rating. The dependent variable is the variable being measured in an experiment. In this case, it is PERFORMANCE.

Explanation:
The fruit of the mistletoe, a parasitic angiosperm, is a one-seeded berry. In members of the genus Viscum, the outside of the seed is viscous (sticky), which permits the seed to adhere to surfaces such as the branches of host plants or the beaks of birds. What should be expected of the fruit if the viscosity of Viscum seeds is primarily an adaptation for dispersal rather than an adaptation for infecting host plant tissues
Answer:
We should expect that the fruits should grow in population and spread more easily.
Explanation:
Like the relationship between bamboo and pandas, the relationship between the seeds and the beaks of birds should allow the seeds to spread to other areas more easily that would otherwise be a very gradual process if the seeds did not evolve its viscous ability.

Forming a hypothesis is the first step of the scientific method.
Answer:
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
Explanation:
The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables

will mark Brainliest!!!!!! To corroborate information is to?
find evidence that opposes a scientific position.
find evidence that supports a scientific position.
find evidence that proves a scientific position.
find evidence that disproves a scientific position.
The most correct option as to what corroborating information means would be to find evidence that supports a scientific position.
Corroborate is an English word that means 'to agree with' or 'give credence to'.
Hence:
Finding evidence that opposes a scientific position is a wrong option because that is the complete opposite of what corroborate means. Finding evidence that approves a scientific position is also a wrong option because corroborating a statement does not necessarily make the statement to be scientifically correct.Finding evidence that disproves a scientific position is also incorrect. Corroborate neither translates to approve nor disprove,Therefore, the correct option that clearly explains what corroborate means in the context of science is to find evidence that supports a scientific position.

Prior to the industrial revolution in the mid-1800s, a species of moth had light-colored wings speckled with small black spots. This coloration camouflaged the moths resting on the birch trees growing in their native habitat, since birch bark has similar coloring. In the early 1900s, this changed as dark soot produced by industrial pollution coated birch trees such that the trees lost their speckled coloring. Years later, it was observed that the moths of this species had changed from being light and speckled to being solid black. Which is the most plausible reason for this change
Answer:
The dark colored moths were due to a genetic mutation, and were more than likely present before the Industrial Revolution. Their fitness was low because predators could easily see them on the light-colored trees. They would be eaten before they could reproduce and pass on their genetic mutation. After the trees became darkened by soot, the darker colored moths now had the survival advantage, able to "hide" from predators. The lighter colored moths became more visible to predators, and the advantage shifted. Now, the light colored moths were more visible to predators, were eaten, and didn't have the chance to reproduce. The darker moths with the mutation had the survival advantage, blending in with the soot-covered trees, and were able to reproduce at higher rates, passing the mutation on to later generations.

Answer:
The complete question with its options is:
Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1)_____ system first recognized the falling pencil. It sent signals to the (2)______ system, which then moved the components of the(3) _____ system in order to catch the pencil.
Options:
(1) 1. Nervous 2. Muscular 3. Skeletal
(2) 1. Nervous 2. Muscular 3. Skeletal
(3) 1. Skeletal 2. Digestive 3. Nervous
The answer is:Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1) Nervous system first recognized the falling pencil. It sent signals to the (2) Muscular system, which then moved the components of the(3) Skeletal system in order to catch the pencil.
Explanation:
The nervous system receives the signal that the pencil is falling. In other words, Jenna sees or feels that the pencil falls, so the senses send a signal to the nervous system to produce a response. We call this a stimuli. Once that the nervous system receives and processes the stimuli, it elaborates an answer. The answer is to send a signal to a group of muscles that will move certain bones to make the movement that will catch the pencil. The muscles are from the muscular system, and they are attached to the bones, which are part of the skeletal system. When the muscles contract, they move the bones and make the movement possible.
