lakkis [162]
This question is asking for the number of ATP that is produced by the citric acid cycle and the electron transport chain. 
Citrate is the first biological substance in the citric acid cycle and it is the starting point of the cycle. From one molecule of citrate, the citric acid cycle will produce 2 ATP while the electron transport chain will produce 34 ATP. Therefore, together both the citric acid cycle and the electron transport chain will produce 36 ATP.

Which of the following is a postzygotic isolating barrier?
Jet001 [13]

Answer: The following is a <u>postzygotic isolating barrier </u>:

  • The hybrid offspring of two species of crocodiles can produce normal gametes but cannot obtain a mate.  

Explanation:

<em><u>Reproductive isolation </u></em>occurs when <em>barriers prevent</em> two populations from interbreeding , <u>keeping their gene pools separate.</u>

We can find the Prezygotic isolation that occurs<u> before fertilization </u>can happen.

And the Postzygotic insolation barriers are the reproductive insulation processes that<u> act after the mating</u>. They are all that concern the viability of the individuals produced.

Prezygotic isolation barriers can be temporal, behavioural, geographic , ecological or mechanical; whereas postzygotic isolation barriers include the inviability, infertility or breakdown of hybrid organisms
