Cystic fibrosis is a hereditary disorder caused by a recessive mutation. in a previous marriage, jim had a child with cystic fib
rosis, though neither jim nor his first wife had the disease. jim is now married to martha, who had a brother that died of cystic fibrosis. though martha does not have the disease, she found out that she is a carrier. what is the probability that jim and martha will have a baby with cystic fibrosis?
Jim is clearly a carrier for the disease, as is his new wife.
The distribution will be as such, with C denoted the dominant, non-disease trait and c denoting the hereditary disease. Only cc results in the disease. Martha Jim Offspring: C C c Cc, cC, CC, cc c
There is a 50% chance that the child is a carrier but does not have the disease (Cc) There is a 25% chance that the child inherited no disease allele and therefore is not a carrier (CC) There is a 25% chance that the child has the disease (cc)
The probability of having a baby with cystic fibrosis is 25%
Archaea are the closest modern relatives of Earth's first living cells
Archaea are famous because of living in extreme environments
If it’s super hot (more than 100° Celsius), freezing, acidic, alkaline, salty, deep in the ocean, even bombarded by gamma or UV radiation, there’s probably life there, and that life is probably archaeal species
They’re also considered very resourceful
Many forms of archaea can utilize totally inorganic forms of matter—hydrogen, carbon dioxide or ammonia for example—to generate organic matter themselves
Answer: The carbon dioxide is the output and oxygen is the input of the Scuba apparatus.
Explanation:
The scuba apparatus is a life saving apparatus used by the sea divers. It recycles the exhaled gas and removes the carbon dioxide and compensates for the utilized oxygen gas before the diver is actually supplied with the gas for the purpose of breathing in a circuit. Hence, the carbon dioxide gas is the output and the oxygen is the input.
