what does not contribute to change of seasons ?

Answers

Humans do not contribute to the change of seasons

Answer:

Distance Does Not Cause Seasons

Explanation:

It is a common misconception that seasons occur because of Earth's elliptical orbit around the Sun, with winter occurring when Earth is farthest away from the Sun, and summer when it is closest to it. However, our planet's distance from the Sun has little effect on the onset of seasons.

What's the best and the worst US state in your opinion? Briefly explain your position

Answers

Answer:

The best would be NY, I love it there. And I also like it because of you know the fashion there (like the models and runway stuff). The worst state has to be umm prob alabama. I've never been there but I just dont like how its pronounced. And because it's probably boring there.

Explanation:

Answer:

Okay, let's do this.

Explanation:

The best state in my opinion would be wonderful Nevada. Nevada is a hotspot for a bunch of other states. It has Las Vegas, as well. Compared to the majority of other states, there is a huge demographic for people that would normally want to settle down in a state. Nevada would be that state in my opinion. Nevada is also near a whole lot of other states and the variety of deserts you see along the way is extraordinary.

Onto the worst state in the US, it would honestly be Colorado. Why Colorado you might ask, well Colorado is the main area of racial afflictions. Considerably the most racist state amongst others, such as Kentucky and Alabama. Don't even get me started on South Carolina and West Virginia. But yeah, in my opinion. Some things just don't sit right with me in that state of Colorado.

The characteristics below describe which of the following economic types?

-Individuals pick their own jobs.

-Supply and demand sets prices.

-Companies decide what to sell.

-Trade occurs freely.

Answers

Answer:

The characteristics describe a free market economy.

Explanation:

The free market economy is an economic system that has been become more and more widespread. The reason for its growing popularity comes from the fact that so far it has given the best results when it comes to the development of the countries, but it also enables the business sector to operate freely and outside of the borderds of the country where its seat is. This economic system initially developed in the western world, and during the twentieth century, and especially after the fall of communism it spread out rapidly across the globe.

The free market economic system has many advantages when compared to other economic systems. The companies have total freedom in their choices when it comes to production. The prices and set by the consumers, or rather the consumers choose the best products for the most acceptable prices. The labor force is free to decide where they want to work and to negotiate about their income in accordance with their qualifications. The borders, at least in an economic sense, are open between the countries, so the companies can operate on a much larger-scale.

What’s another species whose individuals could be easily identified using software like Wildbook or LemurFaceID? please hurry asap

Answers

Answer: lol this might be wrong sorry girl

Explanation:

Long-term research of known individuals is critical for understanding the demographic and evolutionary processes that influence natural populations. Current methods for individual identification of many animals include capture and tagging techniques and/or researcher knowledge of natural variation in individual phenotypes. These methods can be costly, time-consuming, and may be impractical for larger-scale, population-level studies. Accordingly, for many animal lineages, long-term research projects are often limited to only a few taxa. Lemurs, a mammalian lineage endemic to Madagascar, are no exception. Long-term data needed to address evolutionary questions are lacking for many species. This is, at least in part, due to difficulties collecting consistent data on known individuals over long periods of time. Here, we present a new method for individual identification of lemurs (LemurFaceID). LemurFaceID is a computer-assisted facial recognition system that can be used to identify individual lemurs based on photographs.

Results

LemurFaceID was developed using patch-wise Multiscale Local Binary Pattern features and modified facial image normalization techniques to reduce the effects of facial hair and variation in ambient lighting on identification. We trained and tested our system using images from wild red-bellied lemurs (Eulemur rubriventer) collected in Ranomafana National Park, Madagascar. Across 100 trials, with different partitions of training and test sets, we demonstrate that the LemurFaceID can achieve 98.7% ± 1.81% accuracy (using 2-query image fusion) in correctly identifying individual lemurs.

Conclusions

Our results suggest that human facial recognition techniques can be modified for identification of individual lemurs based on variation in facial patterns. LemurFaceID was able to identify individual lemurs based on photographs of wild individuals with a relatively high degree of accuracy. This technology would remove many limitations of traditional methods for individual identification. Once optimized, our system can facilitate long-term research of known individuals by providing a rapid, cost-effective, and accurate method for individual identification.

Answers

Answer:

In January 1919, two months after the fighting in World War I ceased, a conference was convened at Versailles, the former country estate of the French monarchy outside Paris, to work out the terms of a peace treaty to officially end the conflict.

Though representatives of nearly 30 nations attended, the peace terms essentially were written by the leaders of the United Kingdom, France and the United States, who along with Italy, formed the “Big Four” that dominated the proceedings. The defeated countries—Germany and allies Austria-Hungary, Turkey and Bulgaria—weren’t invited to participate.
