Answer:
The solar system formed about 4.5 billion years ago from a dense interstellar gas and dust cloud. Then, the cloud collapsed, possibly due to the shockwave of a nearby exploding star called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
The nebular hypothesis is the most widely accepted model of how our solar system came to be. According to the model, the solar nebula—a region in a giant cloud of gas and dust—began to collapse and contract under its gravity about 4.6 billion years ago. The center of the cloud became hotter and hotter. Then, the system started to rotate as it got more desirable and condensed. This was the beginning of the solar system's formation.
Over time, the cloud formed the Sun and a protoplanetary disk that gradually coalesced to form planets and other objects. The Sun was born out of a concentration of kinetic energy and heat at the center, while debris rotating the nebula collided to create the planets.
Imagine you are interested in finding out how much time it takes on average to walk from one end of your school to the next. You’ve decided to figure this out on your lunch break and are able to complete the walk 20 times what would your algorithm look like where could a loop show up? Note: you do not have to write your algorithm in a programming language. You can write it out in English or in pseudocode code
Start a timer at one end of the school.
Walk at a normal pace to the other end of the school while timing the walk with the timer.
Stop the timer once you reach the other end of the school.
Record the time taken to walk from one end of the school to the other.
Repeat steps 1-4 twenty times.
Calculate the average time taken by adding up the recorded times and dividing by 20.
A loop could show up in step 5, where the process of walking from one end of the school to the other and recording the time is repeated 20 times. This could be accomplished using a for loop in a programming language, where the loop would run 20 times, with each iteration representing a walk from one end of the school to the other.

A country has the following population statistics: CBR = 1. 0% CDR = 1. 0% immigration = 1. 0% emigration = 2. 0% What is the growth rate of the population in this country? T: (CBR + Immigration) - (CDR + Emigration) = Population Growth Rate A. 5% B. 10% C. - 18% D. -1. 0%
Answer:
-1.0%
Explanation:
T: (CBR + Immigration) - (CDR + Emigration) = Population Growth Rate
Substituting the given values, we get:
T: (1.0% + 1.0%) - (1.0% + 2.0%) = Population Growth Rate
T: 2.0% - 3.0% = -1.0%
Which demographic transition stage has an age structure with the following characteristics: falling birth rates, falling death rates, small number of elderly people?
Stage 1
Stage 2
Stage 3
Stage 4
Answer:
Explanation:
The demographic transition stage that typically exhibits the characteristics of falling birth rates, falling death rates, and a small number of elderly people is Stage 2 of the demographic transition model.
In Stage 2, a society experiences significant improvements in healthcare, sanitation, and living standards. These advancements lead to a decline in mortality rates as diseases are better controlled, and access to healthcare improves. However, birth rates remain high, resulting in a rapid population growth.
During this stage, the age structure of the population tends to be dominated by young individuals, as the decline in mortality rates leads to a larger proportion of children surviving to reproductive age. The number of elderly people in the population remains relatively small because the declining birth rates have not yet resulted in a significant aging population.
It is important to note that the demographic transition model is a simplified representation of population dynamics, and real-world scenarios can have variations and overlap among stages. Additionally, different countries or regions may progress through the stages at different rates and have unique demographic patterns.
Answer:
Stage 2
Explanation:
The following code simulates the movement of a golf ball in the air after it's been hit. initialVelocity ← 44 accelFromGravity ← -9.8 x ← 0 y ← 0 t ← 0 REPEAT UNTIL (y < 0) { x ← initialVelocity * t; y ← (initialVelocity * t) + ((accelFromGravity * (t*t)) / 2) DISPLAY(x) DISPLAY(y) t ← t + 1 } Which statement best describes why this simulation is an abstraction?
Answer:
It leaves out details that do not effect the results as much, such as air resistance or golf ball material.
Explanation:
A simulation is an abstraction of a complex phenomena that captures the higher-level details that are necessary for the purposes of the simulation and excludes other details.
Help :) Two pigs with curly tails breed and have six offspring. One of the piglets has a straight tail. What is the most likely explanation for this?

Explain how the process of globalization contributed to the diffusion of sugarcane from its hearth of domestication.
The process of globalization has played a significant role in the diffusion of sugarcane from its hearth of domestication. Sugarcane is believed to have originated in Southeast Asia, and from there, it spread to other parts of the world through various channels, including trade, migration, and colonialism. Globalization, in its modern form, has accelerated the diffusion of sugarcane to different parts of the world, leading to its widespread cultivation and consumption.
One of the primary drivers of the diffusion of sugarcane was the global trade network that emerged in the 16th century. The European powers established trade routes to Asia, Africa, and the Americas, and in the process, they introduced sugarcane to different parts of the world. The Portuguese, for example, introduced sugarcane to Brazil, which would later become the largest producer of sugarcane in the world. The Spanish, on the other hand, introduced sugarcane to the Caribbean, which would become another major sugarcane-producing region.
Another factor that contributed to the diffusion of sugarcane was the movement of people. Globalization facilitated the movement of people from one part of the world to another, and in the process, they brought with them their cultural practices, including agriculture. The Indian indentured laborers, for example, were brought to the Caribbean in the 19th century to work on sugarcane plantations. They brought with them their knowledge of sugarcane cultivation and processing, which contributed to the growth of the industry in the region.
Finally, colonialism played a significant role in the diffusion of sugarcane. The European powers established colonies in different parts of the world and used their resources to cultivate cash crops, including sugarcane. The British, for example, established sugarcane plantations in India, which would become another major producer of sugarcane in the world. Similarly, the French established sugarcane plantations in Mauritius, which would become a major producer of refined sugar.
In conclusion, the process of globalization has contributed significantly to the diffusion of sugarcane from its hearth of domestication. The global trade network, movement of people, and colonialism have all played a role in the spread of sugarcane to different parts of the world. Today, sugarcane is one of the most widely cultivated and consumed crops in the world, with significant economic and cultural significance.
