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:
the lightbulb will turn on
Explanation:
because in the circuit electricity is flowing from the battery through the wire into the lightbulb, giving it enough energy to turn on.
Answer:
C. All living organisms have the same four nitrogenous bases in common with each other.
Explanation:
Because all living organisms have the same 4 nitrogenous bases in common with each other but different sequences.
Answer:
I'd need the data from the population sizes of the algae, walleye pollock, orca, ocean sunfish and sea turtles. And I'd also need water temperature data, levels of dissolved oxygen.
Explanation:
The jellyfish population may have increased because of an increase in phytoplankton. This leads to an increase in
zooplankton; a decrease in walleye pollock, leading to an increase in zooplankton; or an increase in orcas, leading to a
decrease in sea turtles. Sea turtles, being the main predator for keeping the jellyfish population in check.
Also, if there are more red algae, jellyfish polyps have less place to grow. Without it, the polyps can attach itself on every surface.
Answer:
a. The operon is under positive control
a.) Loss of enzyme synthesis results from loss of regulatory R gene product which is regulated in the presence of Tis ophane for transcription. Absence of (Tis), transcription is positively controlled by regulatory Rprotein
b.) The proposed model reveals Tis / B complex prevents Tis enzymes from undergoing transcription through the RB operator by binding to the B region
the role of the R protein is
-decrease affinity of Tis / B complex to B region of RB
-bind to the R region on RB
- change the conformation of B region
- yield decreased affinity of Tis / B complex when R gene is lacking preventing transcription in the process
Effects of the RB mutations is that R protein will not bind to Tis / B complex to reduce transcription
