When developing an experimental design, which action could a scientist take to improve the quality of the results?
A. Make only a few changes to the manipulated variable.
B. Identify any biases about the answer to the scientific question.
C. Include as many details as possible when writing the conclusion.
D. Share her ideas through peer review.
Answer:
B
Explanation:
This helps improve the quality.
The action that could a scientist take in order to improve the quality of the results is as follows:
Identify any biases about the answer to the scientific question.Thus, the correct option for this question is B.
What is an Experimental design?The Experimental design may be characterized as a methodology of research in the field of sciences in which a controlled experimental factor is exposed to special treatment with the intention of comparing with a factor kept constant.
The identification of partiality during the designing of an experiment is foremost important. This is because it significantly leads to an error or it affects the overall quality of the results on the basis of valid evidence.
Therefore, identifying any biases about the answer to the scientific question is an action that could a scientist take to improve the quality of the results. Thus, the correct option for this question is B.

How are the herring differently from “normal hearing?
Answer: i think that's the answer
Explanation:
Military antisubmarine sonars produce intense sounds within the hearing range of most clupeid fish. The behavioral reactions of overwintering herring (Clupea harengus) to sonar signals of two different frequency ranges (1–2 and 6–7kHz), and to playback of killer whale feeding sounds, were tested in controlled exposure experiments in Vestfjorden, Norway, November 2006. The behavior of free ranging herring was monitored by two upward-looking echosounders. A vessel towing an operational naval sonar source approached and passed over one of them in a block design setup. No significant escape reactions, either vertically or horizontally, were detected in response to sonar transmissions. Killer whale feeding sounds induced vertical and horizontal movements of herring. The results indicate that neither transmission of 1–2kHz nor 6–7kHz have significant negative influence on herring on the received sound pressure level tested (127–197 and 139–209 dBrms re 1μPa, respectively). Military sonars of such frequencies and source levels may thus be operated in areas of overwintering herring without substantially affecting herring behavior or herring fishery. The avoidance during playback of killer whale sounds demonstrates the nature of an avoidance reaction and the ability of the experimental design to reveal it.

Predict: Will a 1500 kg car moving at the same speed as the tennis ball have more momentum or less? (i think more)
Calculate the momentum of the car and record it here.
Answer:
The car will have more momentum because it has a greater mass. Momentum= mass x velocity therefore if both the objects have the same velocity.
the train is travelling at 15 m/s. It accelerates at 3 m/s² for 20 seconds. How far does the train travel in this time?
The answer is 900m
Hope this helps
The right answer is "900 m"
Answer explanation:
Use the equation: acceleration (a) = change in velocity (v – u) / time taken (t)
Rearrange to solve for the final velocity (v):
v = u + at
Substitute in values and solve:
v = 15 m/s + 3 m/s2 × 20 s = 75 m/s
Rearrange the equation for uniform acceleration (v2 – u2 = 2as) to solve for distance (s):
s = (v2 – u2) / 2a
s = ((75 m/s)2 – (15 m/s)2) / (2 × 3 m/s2)
s = (5,625 m2/s2 – 225 m2/s2) / 6 m/s2
s = 5400 m2/s2 / 6 m/s2
s = 900 m

The lowest point in the state of Louisiana is New Orleans. The city’s elevation is 8 feet below sea level. Write the elevation of New Orleans as an integer.
Answer:
-8
Explanation:
sea level is another way of saying zero. If something is above or above sea level it is a positive integer. like a regular number. if something is below sea level it is a negative integer like negative numbers. They said 8 is the elevation but new orleans is BELOW sea level. that means the integer we are looking for is going to be a negative number. 8 is the number they told us and since it is below the sea level. The integer of new orleans that represents its elevation is -8.

Which of the following are conductors? (Select all that apply).
rubber
metals
plastic
tile
carpet
Answer:
metals, and tile
Explanation:
i think
Answer:
metalstileExplanation:
The flow of electricity is called current. Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators. The tile is a good heat conductor so it moves heat away from your feet while the carpet is a good heat insulator so it does just the opposite of the material that is the conductor. Carpet is not conductive, neither is concrete or dry wood. A flow of electricity is caused by a flow of electrons. Only materials that form electron clouds and those with free ions in aqueous states can conduct electricity.

How are scientists monitoring and studying the effects on the herring?
Answer:Work by biologists and marine scientists over the past 10 years has covered such commercial resources as shrimp, scallops, herring and cod. Establishing tolerance levels for these and other species is one of the tools needed to determine how Barents Sea oil production can be pursued in an environmentally acceptable way. Tolerance levels are measured when a species is at the larval stage, the phase in its growth where it has the greatest vulnerability to oil pollution.
