According to thw big bang theory of the orgin of the universe the universe has expanded from a hot dense state into a vast, cooler state. What would be considered scientific evidence supporting this theory

Answers

The scientific evidence is that the distant galaxies are moving away from us at a very high speed. This gives us an idea that the universe was once joint and suddenly exploded after the big bang and started to expand at a speed faster than light.

Tại sao con người chúng ta lại sốt nhiều lần như vậy?

Answers

Answer:

Fever is an elevated temperature of the human body that is substantially beyond the normal range. Normal body temperature fluctuates daily from about one degree below 98.6 degrees Fahrenheit to one degree above that number. Lower body temperatures usually occur before dawn; higher temperatures in the afternoon.

Body temperature also varies slightly depending on where on the human body it is measured. Rectal (internal) temperature tends normally to be higher than skin (surface) temperature. Oral and armpit temperatures can approximate actual body temperature and are more convenient to measure.

LeeAnn wants to organize her data from researching the effect of hours of sunlight on plant growth to see if there is a trend in the data. Which would be the best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth?in a line graph

in a data table

in an area graph

in a pie graph

Answers

The best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth would be in a line graph.

A line graph is a chart that displays quantitative values over a period of time. A line graph is commonly used to display trends in a dataset and to evaluate how the data has changed over time. The line graph is made up of a horizontal x-axis and a vertical y-axis and each axis is labeled with a data type. In a line graph, the data points are plotted and are later joined by a line. The direction of the lines across the graph produces patterns that show the relationship between all the different variables in a dataset.

The best way to plot her data would be a line graph. With a line graph she would most easily explore the relatonship between all the different variables that play an effect in the growth of plants. Doing this, she would be able to maximize her data visually.
