It is said that the materials found in the giant cloud that formed our solar system are comparable to the ones we have in the solar system today, which are Hydrogen and Helium!
Answer:
The answers are c)are the most reinforcing, generate the greatest immediate sensual appeal, and produce the most powerful psychological dependence.
Explanation:
Like all psychoactive substances, amphetamines affect the central nervous system and have stimulating effects (empathy, sensuality, confusion, etc.), producing an alert state along with various reactions in perception. Some individuals also report optical and auditory illusions. On many occasions this is also favored by the existence of intense visual and auditory stimuli, as happens for example at parties. However, most of these desired effects have tolerance with repeated doses of the same substances and even cross tolerance with doses of other substances. With the appearance of this tolerance other effects appear such as aggressiveness, anxiety symptoms, panic attacks, etc.
Among the medical complications related to the use of these substances, acute neurological complications, seizures and cerebrovascular diseases stand out.
Answer:
Fulfillment center: Location where a product is packaged and made ready for delivery.
High-value shipping: See the FedEx Service Guide for more information on declared value maximum liability.
Insulated shipping: Packaging used to ship temperature-sensitive products, like food, to deliver product freshness. For more information, refer to the FedEx perishable shipping page.
Label: Every package has at least one label that provides useful information regarding the product, like how to use and/or transportation directions. Here are our recommendations for using custom labels to market your business.
Lead time: The time it takes for a package to arrive from point A to point B. For example: the time from a customer placing an order, to the arrival of that order at the customer’s doorstep. This includes order processing, manufacturing, and shipping time. Our shipping service portals can help lead you to specific transit
Answer:
Unlike typical mammalian red blood cells, those from amphibians, such as frogs, contain a DNA-bearing nucleus that is visible in the center of the cell. The circulatory system of amphibians is rather unusual, their hearts having three chambers, two atria, and a single ventricle.
NegativePositive
Positive
The design of the amphibian circulatory system is curious because blood accumulates oxygen in the lungs and is then returned to the heart before being pumped into the rest of the circulatory system. Therefore, a mixing between oxygenated and deoxygenated blood occurs as blood returning to the heart from the lungs is mixed with incoming blood from the body. Frogs handle this situation by having a very slow metabolism and by absorbing some oxygen through their skin. In addition, the ventricle does have some directional control over the distribution of the blood.
Negative
The presence of a nucleus in amphibian red blood cells allows researchers easy access to large quantities of amphibian DNA. Frog blood has both a solid and a liquid portion. The liquid plasma carries solid elements such as red and white blood cells. Blood can be collected from frogs and the red blood cells isolated by centrifugation. After removal of the residual plasma, purified cells can be treated with specific enzymes and detergents to digest the cellular envelope and release DNA from its protein complex. The DNA is then useful for scientific studies and experiments.

- <u>Articulaciones: </u>CODO, MUÑECA, CADERA, TOBILLO, HOMBRO, CRANEO.
Explanation:
Los huesos son órganos que tienen la función de dar estructura, protección y soporte al cuerpo. A los huesos se le unen los músculos, los cuales hacen que los huesos se muevan al contraerse estos. Las articulaciones unen los huesos entre sí y permiten junto con los músculos el movimiento del cuerpo y de sus diferentes partes.
