Answer:
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.
Explanation:
What gene on plasmid act as a marker to select for the recombinant DNA
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.

The statement which represents a common problem of urbanization is that most homes are built with poor materials or in dirty or unsafe living conditions. Thus, the correct option for this question is C.
What is deforestation?Deforestation may be defined as the process of elimination of trees and forests for the purpose of urbanization and industrialization along with various human activities. It is the purposeful clearing of forested land.
The great impact of deforestation is that it decreased wildfires. When the number of trees gradually declines, the chances of forest fires and wildfires may also reduce with respect to time. But there is an ultimate increase in pollution that may be observed along with habitat defragmentation.

The two specific mechanisms of protein regulation in eukaryotic cells is DNA packaging and protein degradation.
TWO specific mechanisms of protein:DNA packaging: It loose or tight the chromatin that promoted or inhibited the transcription. Degradation of the protein: Proteases split down the proteins.Hence, The two specific mechanisms of protein regulation in eukaryotic cells is DNA packaging and protein degradation.

Explain why sometimes roots act as a source rather than a sink.
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.

After staring at a green and yellow object for approximately one minute, students were asked to turn to look at a
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?
Opponent process theory of color vision explains why they saw the image in different colors.
Opponent process theory of color vision is defined as the way the human
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
which are red and blue were seen after a while.
