Answer;
10 seconds
The maximum interval for pausing chest compressions is 10 seconds.
Explanation;
Compressions should be done at a rate of 100 to 120 compressions per minute at a depth of about 1.5 inches for infants, about 2 inches for children and at least 2 inches but no greater than 2.4 inches for adolescents.
The maximum interval for pausing chest compressions is 10 seconds.
A mutation. Adaption and resistance - evolution, essentially. Those who survived the antibiotic developed a mutation which was able to resist the antibiotic and this became passed down to offspring.
Hope this helps!
Our galaxy's arms spiral outward. The Milky Way is a type of galaxy called a spiral galaxy.

Our galaxy does not contain the universe: the universe contains at least one hundred billion galaxies.

Answer: Codominance
Explanation: We have dominant genes and recessive genes.
Dominant gene are gene that are been expressed. example for a tall individual (TT) it means the gene for tallness is been expressed while a recessive gene are genes that are not been expressed .Example An individual who is short (tt) could have the gene for tallest in a recessive form but expresses shortnes.
Complete dominance occur when both allele present are expressed in the phenotype of an individual i.e non of the gene expression is masked or recessive. Codominance is a deviation from mendelian's principle of Inheritance and often time result into a new phenotype.
E.g A white plant cross with a Red plant should give a Red colored plant in an heterozygous form in the first filial generation but when there is codominance i.e both allele are expressed we have a pink plant instead of Red
