Answer:
1. the DNA of which has been modified using genetic engineering methods. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species.
2. GM crops are made through a process known as genetic engineering. Genes of commercial interest are transferred from one organism to another. Two primary methods currently exist for introducing transgenes into plant genomes. The first involves a device called a 'gene gun'.
3. Crops do not damage the environment simply because they are GM. Some farming practices, such as the overuse of herbicides resulting in the excessive eradication of wild plants from farmland have been shown to harm the environment. These problems are similar for non-GM and GM crops.
Answer:Asexual Reproduction Sexual Reproduction
Advantages Time Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected
Disadvantages No variation - if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy
Explanation:While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction
The Hertzsprung-Russell diagram is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900's by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the color of stars against their absolute magnitude
Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.
The Hertzsprung-Russell diagram the various stages of stellar evolution. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.
No it isnt a rational nu7mber.
Answer:
Si.
Explicación:
Sí, es posible utilizar nuestro cuerpo para realizar algún trabajo experimental con el fin de obtener más conocimientos sobre el cuerpo humano y sus respuestas. Estos experimentos ayudan a fabricar nuevos medicamentos y nuevos métodos para mejorar la salud del cuerpo. Sin realizar experimentos, no podemos conocer las diversas reacciones que ocurren en su cuerpo y sus beneficios en el cuerpo humano.
