Brrunno [24]3 years ago

Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.

On the planet, PSEG, Rhinoceros Beetles are chosen for leadership positions in government based on their ability to sing Beetle
Sveta_85 [38]

Answer:

homo-zygous lethal dominant

Explanation:

A homo-zygous lethal pattern is a type of inheritance where an allele is lethal in homo-zygous individuals. In normal dominance, the expected genotype ratio when F1 heterozygous individuals are crossed is 1:2:1 (i.e. 1 homo-zygous dominant: 2 heterozygous individuals and 1 homo-zygous recessive), while the phenotypic ratio is 3:1 (3 individuals expressing the dominant allele: 1 individual only expressing the recessive allele). In this case, the homo-zygous lethal allele changes the expected F2 phenotypic ratio to 2:1 (i.e., 2 heterozygous singing Beetles : 1 homo-zygous recessive non-singing Beetles), where the partially dominant allele is lethal in homo-zygous individuals.

If a mouse and a small lizard of the same mass (both at rest) were placed in experimental chambers under identical environmental
Harman [31]

The mouse, because it is an endotherm and therefore its basal metabolic rate is higher than the ectotherm lizard's standard metabolic rate.

<h3>What are endotherms and ectotherms?</h3>

Animals classified as ectotherms and endotherms employ several techniques to control body temperature.

Endotherms are recognized as warm-blooded creatures, whereas ectotherms are also referred to as cold-blooded creatures. Ectotherms and endotherms vary primarily in that endotherms control their body temperatures by sustaining bodily functions, but ectotherms depend on external sources like sunlight to do so. Ectotherms include invertebrates, fish, amphibians, and reptiles while endotherms include mammals and birds.
