A biologist in a laboratory reports a new discovery based on experimental results. If the experimental results are valid, biologists in other laboratories should be able to:
1: Repeat the same experiment with a different variable and obtain the same results.
2: Perform the same experiment and obtain different results.
3: Repeat the same experiment and obtain the same results.
4: Perform the same experiment under different experimental condition.
Answers
Answer:
repeat the same experiment and obtain the same result
explanation...
Getting the same result when an experiment is repeated is called replication. If research results can be replicated, it means they are more likely to be correct.
Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.

What gene on plasmid act as a marker to select for the recombinant DNA
Answers
Genes that are preferably used in the plasmid need to be resistant from various antibiotic effects. The genes that are preferably used as selectable markers ( antibiotic resistant ) to select r DNA are: nptII, hpt, bar and gox.
What are markers ?Markers in the r DNA are actually the genes that are purposed to check if the nucleic acid sequence has been inherited in the host DNA or not.
Genes that are used in the markers need to be antibiotic resistant as it becomes easier to detect the plasmid containing bacteria when they are grown in the selectable culture media.
Thus nptII being resistant to amino glycoside antibiotics,gox to the glycophosphate and hpt gene to detect trans gene and bar in the self defense are selected most probably.

white wall. Within seconds, they were shocked to see the image of the object in red and blue. Which theory of color
vision helps explain what the students saw?
Answers
Opponent process theory of color vision explains why they saw the image in different colors.

visual system processes information about color in an opposite manner. The
color viewed are usually complementary to each other.
The opponent process cells are located in the thalamus and in the example
given, green and yellow were first seen before the complementary color

Ya antes del fin del siglo XIX Ehrlich había usado el término "complemento" para designar la actividad del suero que podía complementar la capacidad de los anticuerpos específicos de lisar bacterias. Pero es Jules Bordet quien descubre (1895) este componente, caracterizado frente a los anticuerpos por su termolabilidad. En 1907 Ferrata comienza a caracterizar algunos de sus componentes recurriendo a métodos de diálisis. Por motivos meramente cronológicos, los componentes iban recibiendo denominaciones a base de números tras la letra "C" conforme se iban descubriendo. Por esta razón, su orden de actuación no guarda en general relación con su nomenclatura.

Explain why sometimes roots act as a source rather than a sink.
Answers
Answer:
Explanation:roots suck up nutrients
Roots can sometimes act as a source rather than a sink for glucose during unfavorable periods of growth.
What are sources/sinks?Sources are organs of plants where glucose is manufactured and sinks are organs of plants where glucose is stored.
Usually, the synthesis of glucose happens in leaves while some roots serve as storage organs for glucose.
When conditions are bad for glucose synthesis in leaves, storage roots sometimes become sources and send glucose to leaves for respiration.
