D. A describes what someone or something is doing in the environment. B is similar in nature and thus wrong. C, relative location is relative to a person or thing,"He is close to the statue". D is correct because the location of the address never changes.
A. Used fire to do controlled burns
The result of controlled burns were highly beneficial to both the Aborigines and the environment. The burnt remains of the burns were very fertile and encouraged the growth of new vegetation that would not have been able to flourish if the older growth had not been removed. The removal of old vegetation also resulted in a low chance of wild fires. Further more new vegetation was able to attract wildlife to graze, making hunting easier.
The concept of controlled burns is still used today and was/is also practiced by First Nations in North America.
Answer:
Number 2- Misreading the data is a very serious issue
Explanation:
Answer:
Arizona and Sonora share the same ecosystem, the Sonoran Desert region. They share common history, several Native American tribes on both sides of the border, and they have six border twin towns. The natural boundary is 361 miles long and it has never been a totally closed border. Arizona needed Sonora's miners and ranchers and they have been the biggest source of migrants to the USA.
Because of the constant flow of people across the border, the Arizona-Sonora region developed its own separate identity. Many people living there are bilingual and commute daily to the other side of the border for work. Their value system has been affected by the proximity of a different culture. As a result of that, intercultural and interracial mixing took place that created a generation of people who feel a connection to both countries at the same time. Prejudices have been reduced and stereotypes abolished.
The interdependence between the USA and Mexico has always been and still is business related. Starting with vegetables trading, the cross border shopping and manufacturing developed into big industry today. A major economy connection has developed through the maquiladora sector. Arizona based companies operate about 30% of maquiladoras in Sonora and Sonora's economy is dependent on this and the automobile industry in Arizona.
Cross-border shopping, tourism ( for pleasure and medical reasons), joined environmental projects, bilingual schools and cultural events are all parts of the interdependence between the two countries.
Explanation:
Answer: (b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others with the Sun at precise center of the ellipse. Minor axis is the same as other ellipses.
Explanation:
According to the first Kepler Law of Planetary motion, the orbit of a planet around the Sun, is in the form of an ellipse <u>with the Sun at one of the two foci of that ellipse</u>. This is also valid for any mass orbiting another mass greater than the first one in the space.
In this context, the ellipse is a conic, whose eccentricity is between 0 and 1. So, when its value is 0 we are talking about a circular orbit and when it is 1, a parabolic orbit.
That is, the nearer to the value of 1 (without reaching 1) the eccentricity of the orbit is, the more elliptical it will be.
In this sense, the only option that is incorrect is:
(b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others <u>with the Sun at precise center of the ellipse</u>. Minor axis is the same as other ellipses.
This statement contradicts Kepler's first law, because the Sun is <u>at one of the two foci of that ellipse</u>. The only way in which the Sun can be at the very center of the orbit is when we talk about a circular orbit. Since a circumference is a especial case of an elipse with eccentricity zero and we get only the center instead of the two foci.
