Joan guesses that adding fertilizer to a group of tomato plants will make the plants grow larger. She adds fertilizer to twenty plants and doesn't add fertilizer to twenty other plants. Which of these terms best describes the twenty unfertilized plants?

Answers

Answer 1

Answer:

The twenty unfertilized plants could be described as the control group or the comparison group.

Explanation:

Generally, a control group is a group of subjects that is not exposed to the experimental treatment or intervention being studied. The purpose of a control group is to provide a baseline or comparison for the experimental group. The experimental group in this scenario would be the twenty plants that received fertilizer. The control group, the twenty unfertilized plants, serves as a reference point to assess the effect of the fertilizer on the growth of the plants. This allows the experimenter to determine if the fertilizer is the cause of any observed differences in plant growth between the two groups.

What are some common employers of biomedical engineers

Answers

Hospitals, universities, research institutions, and manufacturers of diagnostic and medical instruments are some typical employers of biomedical engineers.

Biomedical engineers are experts who contribute to the creation of cutting-edge medical technology.

A strong academic background in a relevant field, such as physics, mechanical engineering, electrical engineering, or biomedical engineering, is necessary to become a biomedical engineer. For graduates who are not engineers, postgraduate degrees can be advantageous and may even be required for specific positions.

Gracias Read the following passage and answer the questions that follow.The Strange Case of Dr. Jekyll and Mr. Hydeby Robert Louis StevensonPart 11. Mr. Utterson the lawyer was a man of a rugged countenance, that was never lighted by a smile; cold, scanty and embarrassed in discourse; backward in sentiment; lean, long, dusty, dreary, and yet somehow lovable. At friendly meetings, and when the wine was to his taste, something eminently human beaconed from his eye; something indeed which never found its way into his talk, but which spoke not only in these silent symbols of the after-dinner face, but more often and loudly in the acts of his life. He was austere with himself; drank gin when he was alone, to mortify a taste for vintages; and though he enjoyed the theatre, had not crossed the doors of one for twenty years. But he had an approved tolerance for others; sometimes wondering, almost with envy, at the high pressure of spirits involved in their misdeeds; and in any extremity inclined to help rather than to reprove.2. "I incline to, Cain's heresy*," he used to say. "I let my brother go to the devil in his quaintly 'own way.'" In this character, it was frequently his fortune to be the last reputable acquaintance and the last good influence in the lives of down-going men. And to such as these, so long as they came about his chambers, he never marked a shade of change in his demeanour.3. No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good-nature. It is the mark of a modest man to accept his friendly circle ready-made from the hands of opportunity; and that was the lawyer's way. His friends were those of his own blood or those whom he had known the longest; his affections, like ivy, were the growth of time, they implied no aptness in the object. Hence, no doubt, the bond that united him to Mr. Richard Enfield, his distant kinsman, the well-known man about town. It was a nut to crack for many, what these two could see in each other, or what subject they could find in common. It was reported by those who encountered them in their Sunday walks, that they said nothing, looked singularly dull, and would hail with obvious relief the appearance of a friend. For all that, the two men put the greatest store by these excursions, counted them the chief jewel of each week, and not only set aside occasions of pleasure, but even resisted the calls of business, that they might enjoy them uninterrupted.*The biblical story of Cain and Abel is a story about two brothers who gave offerings to God. Abel's offering was accepted by God, but Cain's was not. Jealous, Cain killed his brother. When God asked Cain where Abel was, Cain said, Am I my brother's keeper? By saying this, Cain implied that what his brother did was his own business. (Genesis 4:1-16)What do other people think of Mr. Utterson's friendship with Mr. Enfield?

Urbanization Design ChallengeIt's time to be an urban planner and build your community! Engineering problems must adhere to criteria and constraints. Criteria are specific needs of your community that should be met by your design. Constraints are the limitations that should be considered before building your community. Here is your urbanization design challenge:Engineering Challenge: Design a sustainable city that provides resources to all people and protects the surrounding ecosystem.Instructions:1. Your city design should meet the following:Community Needs (Criteria)Environmental Limitations (Constraints)Provide enough energy and resources for all homes and businesses.Protect human health and the environment.Don't put plants or services (except for parks) in water, wetland, or forested areas.Don't increase water pollution by placing buildings in heavy rain or snow zones.2.

Use the virtual simulation to design your city. You can place as many items in your city as you wish. But don't forget the needs and limitations described in step 1. For example, if you place housing in your city (100 homes), the residents need two parks to meet their recreational needs. Use the three maps in the simulation to guide your icon placement.4. When you have completed your city, use the capture button in the simulation to take a picture of it. Place the picture of your city in the 01.08 Urbanization Virtual Lab Worksheet.InstructionsYou will build a community by placing the icons representing housing and city resources on the map. After selecting an icon, it will appear at the top of the map. Its description will also appear. To move an icon, select and move it to whatever location you wish. When only using your keyboard, hold the shift button and use the arrow keys. To delete the icon, move it to the trash can or use the "Clear Maps" button.Geology, climate, and suitability maps are provided to guide your placements. Select each map for a description. Reselect the map to clear it.Place your housing icons, then your services, food, energy, and waste control icons.Finalize your design.
