Where did the first cell on earth come from?
Answer:
c) Electron flow from ETC generates proton gradient.
Explanation:
The true statement among the given options is “Electron flow from ETC generates proton gradient.”
(As indicated to its name, electron transport chain is responsible for the transfer of electrons and eventually it triggers the protons transfer transverse the membrane. This transfer of electron creates an electrochemical proton gradient that triggers the synthesis of ATP. Hence, at certain point electron flow from ETC is responsible for generation of proton gradient.)
Answer: Option C
Explanation:
The homozygous pair produces single type of gamete and heterozygous pair produces two different types of gametes.
Here, BBTt has B trait in homozygous condition and so only B allele will be passed as gamete to the next generation.
Since, Tt is in heterozygous condition then T allele will be passed on to half gamete and t will be passed on to half of the gamete.
So, the gametes will be BT and Bt only.
Hence, the correct answer is Option C.
Reason*
waters from natural sources contain minerals. these minerals can either be basic or acidic, thus changing the pH of water accordingly.
