Answer:
Experimento, observación directa, encuesta, entrevista, etc.
Explanation:
El método de investigación implica el ordenamiento sistemático de la información científica con el objetivo final de confirmar o rechazar una hipótesis de trabajo. Antes de comenzar una investigación, es imperativo conocer cuales son los tipos de datos que permitirán responder las preguntas planteadas en dicho proceso. Para ello, es necesario tener en cuenta que los datos resultan útiles cuando pueden ser clasificados y/o medidos, es decir, cuando ellos representan variables con diferentes estados (cuantitativos) o cuyos valores son fluctuantes entre sí (cuantitativos). Los datos deben cumplir una serie de requisitos, estos deben ser confiables (no falseables), objetivos (presentar el mismo valor en medidas independientes) y válidos (útiles para la investigación). Los métodos más comúnmente utilizados para recopilar datos son los siguientes: 1-observación directa: por ejemplo, mediante la observación de variables en su contexto natural; 2-experimentación, donde la información es obtenida en condiciones controlada; 3-encuestas, las cuales consisten en la toma de datos estadísticamente normalizados; 4-entrevistas, que representan un método indirecto de obtención de datos cualitativos.
Answer:
Carbon dioxide - with water - is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase

Answer:
- Interspecific competition between sea urchins and Stellar's sea cows
- Predation fo sea urchins by sea otters
Explanation:
As urchins and Stellar's sea cows feed on seaweed, since these algae are low in quantity, these two organisms end up competing for food, creating an inter-specific competition, which occurs when two organisms compete for the same resource within a same ecological niche. However, as the hedgehog has advantages in this niche, this competition was interrupted.
The otters' predatorism in relation to sea urchins was also interrupted, as the otters reached a very low population level, failing to control the hedgehog population and generating an environmental imbalance.
Basically, macro molecules fall into four classes;
The lipids
The carbohydrates
The proteins
The nucleic acids
The fact that their role revolve around energy production by carbohydrates, energy storage and insulation by lipids, storage of genetic material by nucleic acids and structural support by proteins means this can be equated to the executive arm of the government that deals in provision of social amenity, protection, creation of job opportunities and sustaining a country's culture.
Answer:
the balance is everything must have a process of living and dying in an ecosystem. such as, an animal killing another animal for prey to eat it, that is a process. in a water ecosystem, fish lay eggs and come out and usually get eaten by a bigger animal, as they grow up, usually by bigger fish itself such as the Grayling.
