Answer:
b. A second marker in the knock-out cassette, that if inserted into the genome results in cell death when plated on selective media.
Explanation:
General recombination, also known as homologous recombination, refers to the naturally occurring process of exchange of genetic material between pairs of homologous DNA sequences. This process (homologous recombination) can be exploited by genetic engineering to insert DNA segments of interest at target genes. Moreover, a cassette is a mobile DNA segment containing almost a gene and a recombination site, which is integrated into the <em>locus</em>/<em>loci</em> of interest by homologous recombination. A cassette may contain a DNA segment called 'negative marker' which prevents growth under particular conditions, while a positive marker permits growth under certain conditions. In consequence, a second marker consisting of a drug cassette may be used as a negative marker in order to evidence its insertion by inducing cell death when they are plated in selective conditions.
Answer:
Sun and Moon
Explanation:
the sun's tide-generating force is about half that of the moon, and the moon is the dominant force affecting the Earth's tides.
Most of the functions of your intestines are a result of the signals sent by your autonomic nervous system (ANS). It is a fundamental constituent of the peripheral nervous system.
<h3>What is the autonomic nervous system?</h3>
The autonomic nervous system (ANS) refers to a fundamental part of the peripheral nervous system capable of regulating diverse physiological functions.
This system (autonomic nervous system) is responsible for regulating involuntary processes such as blood pressure, heart-pumping, respiration rate, digestion, etc.
The parts of the autonomic nervous system include the sympathetic nervous system and parasympathetic nervous system.

Since chemical spills are very harmful to aquatic/land life for both plants and animals, plants probably wouldn't grow back and animals could be mutated or even killed, decreasing the population of that species. A volcano eruption, can be both good and bad, since a volcano can kill animals and plants, but ash from a volcano is extremely fertile, so plants can regrow, which in turn brings animals back so they can feed on those plants.
