Answer:
The correct answer is - Cytosine pairs with guanine and thymine pairs with adenine.
Explanation:
In a real DNA or B-DNA the interaction or arrangement of the nitrogen bases are defined and almost remain the same. The bond between the nitrogen bases is hydrogen bonds.
The hydrogen bond between the purine and pyrimidines (types of nitrogen bases) are as follows:
Adenine always pairs with Thymine and Guanine always pairs with Cytosine in a real DNA molecule.
Answer: One advantage is, well, the water. There’s plenty of it and it’s all around. Therefore, most aquatic plants do not need adaptations for absorbing, transporting, and conserving water. They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticles on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants.
Snakes might eat grains but it also eats grasshoppers that makes it a consumer.
Frogs eat grasshoppers also and similarly it is also a consumer.
A person might say that from this the answer surely is "both eat grasshoppers"
But the answer is "both are consumers" since eating of grasshoppers is a feature of consumers.

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.
