Answer:
a través de introducción antrópica
Explanation:
La introducción antrópica es decir, la acción del hombre (muchas veces de modo intencional), es la causa más común por la cual una especie exótica puede colonizar un nuevo ambiente. Generalmente, las especies exóticas compiten con especies autóctonas por la disponibilidad de recursos (alimento, hábitat, etc). Las especie invasoras que se adaptan a nuevos ambientes a menudo incrementan rapidamente su rango de distribución ya que el ecosistema no posee los mecanismos naturales para evitar su crecimiento poblacional (por ejemplo, presencia de depredadores adaptados para cazar la nueva especie). Como consecuencia de este proceso, una especie invasora puede convertirse en un serio riesgo para la biodiversidad y el equilibrio del ecosistema, causando muchas veces la extinción de especies autóctonas que son esenciales en la cadena trófica del ecosistema.
Answer:
When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.

Explanation:
Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.
Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:
Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats
Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.
Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.
Answer:B
Explanation: because gene are made up of DNA and are the one which made Chromosome and allocated at point called locus
