Answer:
It can lead to increased incidence of drug resistant bacteria.
Explanation:
Many farm animals used for meat are given antibiotics to promote their growth. They are also given these antibiotics to treat certain diseases caused by pathogenic microbes such as bacteria.
The continual use of antibiotics will however lead to increased incidence of drug resistant bacteria present in the world at large due to the exposure of the bacteria to these drugs resulting in the formation of resistant species of the bacteria with time .
Alright so three different alleles are A, B, and O.
A dominant to O
B is dominant to O as well
O is recessive to A and B
Answer:Thus we can conclude that these charcoal fragments are about 11460 years old.
Explanation:
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant = 100
a - x = amount left after decay process = 25
b) for completion of 75 % of reaction
Thus we can conclude that these charcoal fragments are about 11460 years old.
