Tango is a style of music that originated in Argentina and Uruguay, influenced by both regional folk music and European classical dance music. Both Uruguayan and Argentine tango dance music is composed in the easily danceable time signatures of 4/4 and 2/4.

The style of tango music has a great nuance of sensuality and passion. In addition, the musical metric and the strong times accentuate and complement the way in which the tango is danced.

In addition to all these things, the lyrics of the music re-emphasize the passionate character that the dance reflects.

Thus, Tango music can be instrumental, or it can feature a vocalist.

Answer:

Hi!!!! I love how excited you are and your questions are great! I will my information but you will probably still have to do some more research.

Explanation:

1- It really depends on what you are wanting to do with your horse, and how experienced you want your horse to be. I do eventing and my horse was older and not too advanced so he was $6,500. You can find cheaper horses that don't have a ton of experience and train them but as a beginner, I would try to find a nice gentle horse with a lot of experience.

2- My trainer found my horse for me from a family who was done riding him, here are some websites you can find horses on but please try your horse out in person before buying in because you can't always trust the internet. Dreamhorse is my favorite but there are tons so you can also look up more. If you are looking for a jumper you should always try your horse first so I wouldn't buy your horse at an auction.

3- Yes my horse did come with a dressage saddle, dressage bridle, jumping saddle, jumping bridle, halter, and shoes. Some horses do come with tack and some don't but with my horse, both saddles didn't fit so you have to make sure to check. Some horses don't come with shoes and need them especially if you do something like eventing so you will have to check with your farrier (The person who does your horse's feet).

4- It does depend on where you live, and what kind of check-up. For Coggins (papers for your horse that proves that they don't have Equine Infectious Anemia for more information on this lookup "Coggins for horses and what they are for") it costs about 20-60 dollars.

5- A farrier cost depends on what shoes you need (look up the types of shoes) and if your horse needs pads, and snow pads for the winter. it costs about $275 for a trim, all four feet with new shoes, and front feet with pads.

(this might vary from where you live)

6- I own an Appendix (which is a thoroughbred mixed with quarter horse) but he is about 90% thoroughbred.

7- Again It depends on what jumping sport you would like to do, and if you like a strong horse, a kick ride, or in-between. If you are a beginner it doesn't matter too much what breed you have just what the horse's attitude is like. Then if you get up in the levels then it is slightly more important which breed you have.

8- That is great I'm sure that your horse is going to have the best home with you!!!!! Usually, people start training young horses at the age of 4, so I would not get a horse under the age of 7. We retired our old horse at the age of 20 to go to pasters and ride every blue moon, he was an Arabian so they live longer. My horse is 17 and is still totally sound, but it does depend on their history and if they are really used. I think 13-year-olds are good for beginners but it all depends. Horses can be really expensive to feed and maintain but it is all worth it!!!!!!!!

If you want more information, love learning about horses, want some sort of scholarship you should do some research on the United States Pony Club. You can log in on their website and quiz yourself on things like bits, Types of shoes, breeds, colors, and more. Plus it's super fun! You can join a local pony club or if that's not available you can just read the books and learn how to completely take great care of your horse. I hope you enjoy horses because they are wonderful animals, you can look up different jumping sports watch videos, and figure out which one excites you more. I do eventing (you can look it up) I love it because it has three phases. One, Dressage, Two, show jumping, and Three, (my favorite) cross-country! If you are starting this sport I would I would find a trainer or someone to give you lessons, this depends on where you live but my suggestion is Laura Backus you can do your research on her just for fun or if you live close she is the best! Hope this has helped you!!

P.S this is my horse we have come a long way and are totally bonded, I don't have very many pictures of him on my computer but here's something. I love him so so so so much!!!!

Please keep in contact with me and tell me how this goes (and send me a picture of your horse when you get him\her, I would totally love to see how you do)!!!!!!!

From the understanding of how water moves through plants, the only circle that can have a downward pointing arrow only is A.

Water moves through a plant in the following direction:

Soil ----> root -----> stem ----> leaves

Once water gets into the root from the soil, a conducting tissue known as xylem conducts the water upward through the stem of the plant branching off into the leaves through the petiole. from the petiole, water is then conducted to the mesophyll cells.

Circle D represents the root, so the arrow must be upward.

Circle C represents the stem, the arrow continues upward towards the leaves

Circle A and B represent the leaf. The movement of water within the leaf might requires that it is from circle A to circle B. Hence, the only circle that must have an arrow pointing downward only can only be A.

Explanation:

Answer:

d. Are not used up in reactions

Explanation:

This is a property of enzymes. They are not used up since they don't participate in reactions. They just help increase the rate at which it occurs

A key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.

Enzymes may be defined as biocatalysts that increase the rate of a chemical reaction without being changed in the overall process. It may be thought that all sorts of cellular reactions or processes are mediated by enzymes.

Most of the enzymes are proteins. They are highly specific in nature. Enzymes also exhibit enormous catalytic power. They do not alter the equilibrium state of biochemical reactions.

Enzymes typically speed up the rate of a chemical reaction by lowering the activation energy of a particular reaction. Thus, it leads to the conversion of reactants into products at a faster rate.

Therefore, a key feature of enzymes is that they force reactions to occur. Thus, the correct option for this question is E.

The Benefits of Communism

Theoretically, there are many benefits that can be achieved through a communist society. Communist ideology supports widespread universal social welfare. Improvements in public health and education, provision of child care, provision of state-directed social services, and provision of social benefits will, theoretically, help to raise labor productivity and advance a society in its development. Communist ideology advocates universal education with a focus on developing the proletariat with knowledge, class consciousness, and historical understanding. Communism supports the emancipation of women and the ending of their exploitation. Both cultural and educational policy in communist states have emphasized the development of a “New Man”—a class-conscious, knowledgeable, heroic, proletarian person devoted to work and social cohesion, as opposed to the antithetic “bourgeois individualist” associated with cultural backwardness and social atomization.

Other theoretically beneficial ideas characteristic of communist societies include:

People are equal. In a communist regime, people are treated equally in the eyes of the government regardless of education, financial standing, et cetera. Economic boundaries don’t separate or categorize people, which can help mitigate crime and violence.

Every citizen can keep a job. In a communist system, people are entitled to jobs. Because the government owns all means of production, the government can provide jobs for at least a majority of the people. Everyone in a communist country is given enough work opportunities to live and survive. Every citizen, however, must do his or her part for the economy to receive pay and other work benefits.

There is an internally stable economic system. In communism, the government dictates economic structure; therefore, economic instability is out of the question. Every citizen is required to work in order to receive benefits, and those who don’t have corresponding sanctions. This creates an incentive to participate and to encourage economic growth.

Strong social communities are established. In communism, there are certain laws and goals which determine resource and responsibility allocation. If the citizens abide by these laws, this leads to a harmonious spirit of sharing one goal. Consequently, this builds stronger social communities and an even stronger economy.

Competition doesn’t exist. In communist societies, everyone can work harmoniously without stepping on each other’s toes. Work, responsibility, and rewards are shared equally among the citizens. If people have no sense of envy, jealousy or ambitions that counter the goals of the state, then a harmonious economic development can be maintained.

Efficient distribution of resources. In a communist society, the sense of cooperation allows for efficiency in resource distribution. This is very important, especially in times of need and in emergency situations.  

All of the following are environmental influences except Genes. So, the correct option is B.

Genes are defined as functional units of heredity as they are made up of DNA where as chromosome is made up of DNA which contains many genes. Each gene has a special set of instructions for a particular function or protein-coding. Genes are responsible for heredity.

Genes contain instructions that tell the cells how to work and grow where cells are the building blocks of the body. Every part of the body is made up of billions of cells working together. Genes are organized into structures called chromosomes.

Thus, all of the following are environmental influences except Genes. So, the correct option is B.

Answer:

Del intestino delgado ---- torrente sanguíneo --- célula u órgano de almacenamiento.

Explicación:

Después de la absorción de glucosa por el intestino delgado, las moléculas de glucosa se difunden por un gradiente de concentración hacia la sangre capilar dentro de las vellosidades y estas moléculas de glucosa se liberan en el torrente sanguíneo. Cuando las moléculas de glucosa se agregan al torrente sanguíneo, la glucosa puede usarse para la producción de energía o almacenarse en nuestros cuerpos, que puede usarse cuando sea necesario. Si nuestro cuerpo necesita energía esta glucosa es absorbida por las mitocondrias de las células para la producción de energía mientras que por otro lado, si no se requiere energía, estas moléculas de glucosa se almacenan en diferentes órganos en forma de glucógeno.

Answer:

Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity.
