Answer: endothermy
Explanation:
This term describes the ability of some animals to use an internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of environment. When it's cold outside such animals increase their metabolic heat production to keep their body temperature fixed. For this reason, the internal body temperature of an endotherm is more or less independent of the temperature of the environment.
<span>A person who is infected with a pathogen who does not show symptoms is called asymptomatic. Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply.</span>
Answer: No I read it on briticanna.com

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.
