if u.s. population increased 32rom 1980 to 2005, how would you describe the change in per capita co2 emissions for electricity generation

Answers

Answer 1

To describe the change in per capita CO₂ emissions for electricity generation during the period from 1980 to 2005, we would need to calculate the total CO₂ emissions for electricity generation during this time period and divide it by the total population.

Assuming the U.S. population increased from 226 million in 1980 to 293 million in 2005, we can calculate the per capita CO₂ emissions for electricity generation as follows:

Per capita CO₂ emissions = Total CO₂ emissions / Total population

Per capita CO₂ emissions = (Total CO₂ emissions for electricity generation / Total population) * (1/226 million + 1/293 million)

We can then compare this per capita CO₂ emissions value to the per capita CO₂ emissions value in 1980 to see how it has changed.

For example, if the total CO₂ emissions for electricity generation in 1980 were 500 million metric tons and the total population was 226 million, the per capita CO2 emissions for electricity generation in 1980 would be:

Per capita CO₂ emissions in 1980 = 500 million / 226 million = 2.18 metric tons per capita

We can then compare this value to the per capita CO2 emissions in 2005 to see how the change in population has affected the total CO2 emissions for electricity generation. If the total CO2 emissions for electricity generation in 2005 were 600 million metric tons and the total population was 293 million, the per capita CO2 emissions for electricity generation in 2005 would be:

Per capita CO2 emissions in 2005 = 600 million / 293 million = 2.08 metric tons per capita

Therefore, if the U.S. population increased from 226 million in 1980 to 293 million in 2005, the per capita CO₂ emissions for electricity generation decreased slightly from 2.18 metric tons per capita in 1980 to 2.08 metric tons per capita in 2005.

Answers

A fully-fledged language of mixed origin that developed from a complex blending of two-parent languages is the Creole language.

So, the correct option is B.

A creole language is a natural language that emerges from the condensing and blending of many languages into a new one in a very short amount of time; frequently, a pidgin turns into a full-fledged language. French-based creoles like those spoken in Haiti, Louisiana, and Mauritius are examples of creole languages. English-based creoles like Gullah (spoken in the Sea Islands of the southeast United States), Jamaican, Guyanese, and Hawaiian creoles are further examples.

Those with mixed colonial French, African American and Native American heritage are typically referred to as "Creoles" in modern Louisiana. Freed Haitian slaves and their descendants are referred to as "Black Creoles."

Which countries border Saudi Arabia?

Jordan, Iraq, and Kuwait form the country's northern boundary; the Red Sea and the Gulf of Aqaba form its southern and western borders; and the Persian Gulf, Qatar, the United Arab Emirates, and Oman form its eastern and southeast borders.

With Yemen (2000) and Qatar (2001), protracted border conflicts came close to being resolved; the border with the United Arab Emirates is still unclear. Kuwait and Saudi Arabia coexisted in a neutral zone of 2,200 square miles (5,700 square kilometers) along the Gulf coast until a political boundary was established in 1969.

Although they evenly split the region's oil production, each of the two nations is in charge of managing half of its territory. Even though the Saudi-Iraqi Neutral Zone dispute was formally resolved in 1981 by partition, the two nations' ongoing hostilities precluded complete demarcation on the ground.

Answers

The proper order of neural transmission in a neuron is dendrite, cell body, axon, terminal button (C).

This means that the dendrites receive input from other neurons, then the information travels to the cell body where it is processed, then it is transmitted down the axon to the terminal buttons which release neurotransmitters to communicate with other neurons.Therefore, the correct option is (C) dendrite, cell body, axon, terminal button.

Neural transmission begins with the dendrites, which are branch-like structures that receive signals from other neurons. These signals are then passed on to the cell body, also known as the soma, where they are integrated and processed. From there, the electrical signals are transmitted down the axon, a long, slender projection of the neuron. Finally, the signals reach the terminal button, also called the axon terminal, where neurotransmitters are released to communicate with the next neuron in the neural circuit.

Stacking Images For testing: Image AlgebraMain_java Instances of the class Image represent two-dimensional pixel images in Java that can be read from files and URLs, and then rendered to Graphics2D canvases with the method drawImage, as illustrated in the example class ImaqeDemo. These images, no matter where they were acquired, can be further processed and transformed with various ImageFilter instances, as illustrated by our other example ImageOpDemo. We are accustomed to adding up numbers, but we can also "add" images to each other with concatenation, similarly to the way strings are "added" by concatenation. Since pixel raster images are two-dimensional, we can stack them up not just horizontally but also vertically, provided that the dimensions of these images are compatible in that dimension. In your labs project, create a new class ImageAlgebra, and in there two static methods public static Image hatack(Image... images) public static Image vatack(Image... images) for the horizontal and vertical stacking of an arbitrary number of Image objects. Both of these methods are vararg methods, meaning that they accept any number of arguments of type Image, including zero. The horizontal stacking method hat ack (the method names were here chosen to be the same as they are in NumPy) should create and return a new BufferedImage instance whose width is equal to the sum of the widths of its parameter images, and whose height equals the maximum of the heights of its parameter images. This image should then contain all the images together as one row. To implement this method the easiest, just draw the individual images one by one to an appropriate position of the resulting image.) The vertical stacking method vatack works exactly the same but with the roles of width and height interchanged. We can immediately put both of these stacking methods in good use in some recursive subdivision. Define a third method in your class public static Image halving(Image tile, int d) This method produces the result image according to the following recursive rule. For the base case where the depth d equals zero, this method should simply return the given tile. The result for positive depths d is the horizontal stacking of tile with the vertical stacking of two copies of halving (half, d-1) where half is an image constructed from tile by scaling it to half of its width and height. Of course, you will write your recursion to not have any branching, so that the level d activation of this method will create only one level d1 activation. Since linear recursions are redundant, you can then convert it to a loop if you want to. (Recursion is the root of computation. since it trades description for time.
