Hello.
This statment is true.
Have a nice day
Data given
Number of electron = 108
Number of neutron = 158
Required
Mass number=?
Solution
As we know that mass number = No of proton + No of neutron
In any neutral atom the number of proton is always equal to number of electron
So number of proton will be = 108
However the atom has +1 charge which means that one proton is less than no of electron so proton number is 107.
Put values in above formula, we will get
Mass number= 107+108
= 215 Mass number
Answer: A. In the electron transport chain, a series of reactions move electrons through carriers.
B. The products of the electron transport chain are H2O and either NAD or FAD.
E. The electron transport chain is a series of oxidation-reduction reactions that occur in the inner mitochondrial membrane.
Explanation:
the best suitable statement is it transfers energy stepwise from one compound to another, The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons are transferred from one member of the transport chain to another in a series of redox reactions.
A wild-type fruit fly exhibits the most common phenotype in the population.
Fruit flies of the wild type are yellow-brown in colour with brick-red eyes and longitudinal black rings across the abdomen.
An organism or strain displaying the wild type is one that has a phenotype, genotype, or gene that predominates in a natural population of organisms or strain of organisms as opposed to that of naturally occurring or laboratory mutant forms.
The genotype and phenotype standards of reference are wild type. Wild type is regarded as the norm and neither the dominant nor the recessive. In compared to the wild type, mutant alleles are either dominant or recessive.
Fruit flies are distinguished by their tiny size, brown bodies, and red eyes. While these pests themselves are not harmful, they may be a sign of unclean living conditions in the home.
