A student models convection currents in a laboratory activity. How are the convection currents in the student’s model different from the convection currents in Earth’s atmosphere and oceans? The warm air in Earth’s atmosphere and the warm water in Earth’s oceans sink instead of rise. The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below. Convection cells in Earth’s atmosphere and oceans flow in the same direction instead of opposite directions. Cold air in Earth’s atmosphere and cold water in Earth’s oceans are less dense than warm air and warm water instead of being more dense.
Answer: The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below.
Explanation:
In the experiment, the source of heat is the burner below the pot. On Earth this is completely different as the source of the heat on Earth is the Sun which heats us from above instead of below.
The Convection currents still flow in the same direction however because as the sun heats air particles on Earth's surface, they rise but then cool as they keep going up. This makes them go back down where they are then heated up again.
Answer:the heat source for earth’s atmosphere and oceans is the sun, which heats from above instead of below

Answer:
He should do a scientific experiment with volunteers who are students of different courses.
Explanation:
In order for Dr. Wilson's research results to be generalizable across the university, he must provide results that show examples in the most diverse fields that the university covers. This will be simple to establish, if he, when looking for volunteers from his research, instead of concentrating the demand in a single sector of the university, focus on the search for volunteers in all sectors, thus reaching students from the most varied courses, present in institution.
Answer:
surveying every 10th student listed in the university directories about their sleep habits

Explain why the average cell size is similar in blue whale and in an earthworm.
Worth 20 points
Answer: Limited Surface area - Volume ratio
Explanation:
Cells in various organisms usually have the same size be it a blue whale or an earthworm, a Human or a mouse or an Elephant and a squirrel. This is down to the way the cell is structure.
The Cell needs to absorb nutrients to survive while getting rid of waste material. For that to happen it needs an adequate surface area. The problem is that as the cell absorbs more nutrients thereby increasing in volume, this rise in volume occurs at a faster rate than the cell can increase its surface area so the surface area will keep shrinking.
Therefore, in order to have enough surface area to keep up the process of absorption and excrement, the cell will stop growing at the certain point and this process is similar in most if not all organisms.

One paragraphs ( 5-8) sentences on "Why or why not do you think compromising your ideas, for a favorable solution -- for all is necessary"?
Answer:
Find the explanation below.
Explanation:

When their own opinions fail, they might likely listen to our own opinions and respect us for first conceding to their ideas.
Which of the following statistics are most affected by outliers in a data distribution? (Check all that Apply) Group of answer choices: Mean , Standard Deviation, Median, Mode, Range
The median and the range are most affected by outliers in a data distribution
The median and the rangeOutliers in a data distribution have the most significant impact on the mean, standard deviation, median, and range statistics. The mean is strongly influenced by outliers since it considers every value in the dataset. The standard deviation is also affected as outliers contribute to increased variability.
While the median is less affected by outliers compared to the mean, extreme outliers can still shift its value. The mode, representing the most frequently occurring values, is minimally affected by outliers. Lastly, outliers can increase the range if they are the maximum or minimum values in the dataset.

Ms. Harris is comparing test scores in four of her classes. The results are listed below. Class 1 Class 2 Class 3 Class 4 Mean Score: 86.5 Median Score: 84 St. Deviation: 4.56 Mean Score: 79.8 Median Score: 76 St. Deviation: 3.23 Mean Score: 78.5 Median Score: 84 St. Deviation: 7.8 Mean Score: 65.2 Median Score: 61 St. Deviation: 5.67 In which of her classes did most students have the widest range of scores?
Answer: Class 3
Explanation:
Standard Deviation is a measure of dispersion which means that it measures how far apart the values in the dataset are from the mean.
If the values in the dataset are close together, the standard deviation will be smaller. The reverse is true.
The class with the widest range is there the class with the highest Standard Deviation.
With a SD of 7.8, Class 3 has the widest range of scores.

"The government of Peru was a despotism, mild in its character, but in its form a pure and unmitigated despotism. The sovereign was placed at an immeasurable distance above his subjects. Even the proudest of the Inca nobility, claiming a descent from the same divine original as himself, could not venture into the royal presence, unless barefoot, and bearing a light burden on his shoulders in token of homage. As the representative of the Sun, he stood at the head of the priesthood, and presided at the most important of the religious festivals. He raised armies, and usually commanded them in person. He imposed taxes, made laws, and provided for their execution by the appointment of judges, whom he removed at pleasure. He was the source from which every thing flowed, all dignity, all power, all emolument. He was, in short, in the well-known phrase of the European despot, ‘himself the state.’”
William Hickling Prescott, American scientific historian, excerpt from History of the Conquest of Peru, 1847
Source 2
"By night and day they [human offerings] burned, supplied with fuel by an army of slaves who brought it on their backs over the long causeways that connected the island-city with the mainland and its distant forests. These pillars of smoke by day, and ill-omened banners of flame by night, were regarded with fear and hatred by many a dweller in the mountains surrounding the Mexican valley. They were the symbols of a power against which these had struggled in vain, of a tyranny so oppressive that it not only devoted them to lives of toil, hopeless of reward, but to deaths of ignominy and torture whenever fresh victims were demanded for its reeking altars. But while hatred thus burned, fierce and deep-seated, none dared openly to express it, for the power of the all-conquering Aztec was supreme. Far across the lofty mountains, to the great Mexican Gulf on the east, and westward to the broad Pacific; from the parched deserts of the cliff-dwelling tribes on the north, to the impenetrable Mayan forests on the south, the Aztec sway extended, and none might withstand the Aztec arms. If the imperial city demanded tribute it must be promptly given, though nakedness and hunger should result.”
A) Identify ONE way that the two state systems discussed in the passages were similar.
B) Identify ONE way that the two state systems discussed in the passages were different.
C) Identify ONE way the descriptions of state building in the two excerpts reveal that the authors have different evaluations of the civilizations.
Answer:
A. the two state systems were similar, because they both sacrificed people their armies had brought them and were powerful leaders.
B. the two state systems were different, because the leader of the Inca's had created laws, imposed taxes, and handled execution for judges for pleasure which caused him to be feared while the leader of the Aztec's burned their sacrifices night and day which caused them hatred from the dwellers in the mountains surrounding Mexico valley.
C. The authors have different evaluations, because in Source 1 William Hickling describes state building as a sovereign country having everything flow through one man. In Source 2 Kirk Munroe describes State building as a democracy, the Aztecs army a were regarded with fear and hatred by many.
Which of the following graphs reflects this scenario: following the hurricane, the standardized test scores for all students who endured extended power outages fell?
Graph showing a normal distribution with peak in the center of the curve.
Graph showing bimodal distribution with two peaks.
Graph showing positively skewed distribution with peak to the left of the curve and tail to the right.
Graph showing negatively skewed distribution with peak to the right of the curve and tail to the left.
Graph showing a distribution with the peak in the center of the curve.
The correct answer is C. Graph showing positively skewed distribution with a peak to the left of the curve and tail to the right.
Explanation:
The purpose of a graph is to show visually numerical data, including how this changes over time. In the situation presented, the test scores fell or decreased after the hurricane.
In this context, it is expected before the hurricane the test scores were high, which should be represented as a peak in the graph as the rate for test scores was high.
Moreover, once the hurricane occurs the peak should decrease, this is represented as a tail in the graph as the scores of students fell or decrease. According to this, the graph that best represents this situation is one "graph showing positively skewed distribution with a peak to the left of the curve and tail to the right".

Natural erosion can be caused by
a. farming
b. wind
C.
deforestation
d. all of the above
Answer:
b
Explanation:
because framing and deforestation is caused by humans and wind is not.
Natural erosion can be caused by wind. Hence, option B is correct.
What is Natural erosion?During erosion, a geological process in which they are transported by wind or water, earthen materials are worn away. Rock is broken down or dissolved through weathering, a related process that does not involve movement.
Soil erosion primarily occurs when dirt is exposed to strong winds, copious rain, and moving water. Some human endeavors, especially farming and land clearance, increase the susceptibility of soil to erosion.
Sidewalks being soaked by acid rain, waves rushing over rocks at the seashore, ice forming in rock cracks, water washing away dirt in an off-road vehicle site, etc. The naturally occurring process of soil erosion affects all landforms.
Thus, option B is correct.

Note that a business that wants to increase its productivity by acquiring tools that help it create products more effectively would most benefit from an investment in "equipment" (Option C)
What is business productivity?Productivity, in its most formal definition, relates to how successfully an organization turns input (such as labor, materials, machinery, and capital) into goods and services or output. However, it is no longer confined to assessing input/output ratios. Increasing productivity essentially involves working smarter.
Productivity growth throughout time enables organizations to generate more products and services per unit of input. This, in turn, allows for greater wages, promotes economic growth, enhances profitability, and raises tax collections.
