I think the answer would be because if there is an error in the DNA replication, it would affect one generation of cells. if the error would fall in the transcription or translation, there would only be one cell affected.
Answer:
Invertebrates are the organisms in which backbone or vertebral column is absent.
The three macroinvertebrate categories are annelids, mollusks and arthropods.
Annelids are the organisms having segmented body. They are found in moist places. Examples are leeches and earth worms.
Mollusks are the organisms which are enclosed in a calcium carbonate shell. Examples are snails and slugs.
arthropods are the invertebrates which have segmented body and jointed appendages. Examples are insects and crustaceans etc.
Use binomial distribution with p=0.25, n=5, x=2
P(X=x)=C(n,x)p^x (1-p)^(n-x)
P(X=2)=C(5,2) 0.25^2 0.75^(5-2)
=10*0.0625*0.421875
=0.26367
So the probability of 2 of 5 children having type-O blood from these parents is 0.26367.
The reason why good sanitary practice should be observe and done especially in terms of washing dishes immediately after a meal in order to prevent bacteria from going and by this, it makes the enviroment more clean and more safe to people to live in. It is because when plates or used utensils are not cleaned after having it used, bacterial growth could sprout, making the environment dirty and dirt could interfere with someone's health into having them acquire illness that would also affect not only one person but also other people living in the house. That is why good sanitary practice is observed, not only because it promotes cleanliness but it is also because for the better health of the individuals.
