Manuel is performing a scientific investigation to determine whether fertilizer A or fertilizer B is more effective at increasing the growth rate of tomato plants. Manuel measures and separates 30 tomato plants into two equal groups that are planted in identical environments. He gives one group fertilizer A, and gives the other group the same amount of fertilizer B. During the first week of the investigation, he gives the tomato plants in both groups the same amount of water. During the second week, however, he forgets to water the tomato plants being given fertilizer B, but still provides water for the tomato plants being given fertilizer A. Two weeks after planting, Manuel measures the tomato plants and discovers that the tomato plants given fertilizer A have grown much more rapidly than the tomato plants being given fertilizer B. Manuel's resultsA. are not valid because one of the variables was not controlled during week 2. B. are valid because he controlled all of the variables in week 1. C. are valid because he designed his experiment correctly. D. are not valid because he should not have grown the plants in identical environments.

What can be concluded from the data about the reliability and validity of the thermometers?

Answers

Range of error/precision vs. accuracy plots.

Final answer:

The reliability and validity of thermometers are determined by their ability to consistently and accurately measure temperature. Different types of thermometers have varying degrees of reliability and validity. Factors such as the type of the thermometer, its temperature-dependent properties, and the scale of measurement used are crucial in determining reliability and validity.

Explanation:

The reliability and validity of the thermometers can be determined by evaluating their ability to consistently and accurately measure temperature. Reliability of a thermometer refers to its ability to produce consistent results. Different types of thermometers, such as alcohol, liquid crystal, and infrared radiation (pyrometer) thermometers, have varying degrees of reliability.

Validity, on the other hand, refers to the accuracy of the thermometer, in other words, how closely the measurements represent the true temperature. This can be affected by various factors including the type of thermometer, its temperature-dependent properties, and the scale of measurement used.

Two groups of related living things are no longer considered to be the same species whena. They can no longer interbreed.
b. They do not eat the same food.
c. They do not look the same.
d. They become physically separated from each other.

Answers

Answer:

They can no longer interbreed

Explanation:

Which of the following best explains why air pollution that was once blamed for global cooling is now considered responsible for global warming? a. Pollution began reflecting sunlight and heat rather than absorbing it. b. Evidence of global warming became overwhelming. c. Scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it. d. Congress required scientists to assign a cause to global climate change.

Answers

Answer: c. Scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it.

Scientist mistakenly thought pollution reflected sunlight and heat rather than absorbed it. This best explains that air pollution that was once blamed for global cooling is now considered responsible for global warming because the carbon dioxide from greenhouse effect will reflect the sunlight and will split the UV rays and prevent them to enter inside the earth. But carbon dioxide is responsible for increasing the global temperatures.

Answer:

(c) Scientists mistakenly thought pollution reflected sunlight and heat rather than absorbed it.

If the first hill is 20 cm high, the second hill is 0 cm high, and the last hill is 0 cm high, how long does it take the 50 g car to reach the egg?

Answers

The answer is undefined. 

To get how long it takes the 50 g car to reach the egg, the speed is required. Distance is provided from the height of the hills. 

Formula to get the time is:

T = D/S
Time = Distance / Speed

For example, given that the distance is 20 cm and the speed of the 50 g car is 2 cm/s

T = 20 cm / 2 cm/s
T = 10 s

The 50 g car will take only 10 seconds to travel.

Answer:

2.45s

Both coral reefs and wetlands have been destroyed by

Answers

Answer:

human activity

Explanation:

The wetlands and the coral reefs have gradually been destroyed by the humans and their activity. The wetlands were the first to be under the human influence and getting destroyed, while the coral reefs have come to have similar destiny in the last century. The reasons for the destruction are different. The wetlands have in general been destroyed on purpose, be it because they were epicenter of diseases, for making more land for agriculture, or making more land for settlements. The coral reefs have not been destroyed on purpose, but the human activity has resulted in lot of pollution of the ocean waters, as well as changes in the climate, and the fragile corals can not adapt quickly enough to these changes, so they die out quickly.
