Answer:
Explanation:
The plate were supposed to streak by D. radiodurans but unfortunately it was streaked by E.coli.
As there is no other petri plate available, this plate was exposed to the UV for the 30 minutes. The plate was not left uncovered and because of that the total E.coli could not die and another streak of D. radiodurans was done on the same plate.
As a result of incubation there will be growth of both of the organism in the petri dish.
Answer:
Energy released by the electron transport chain is used to pump H+ into <em>the mitochondrial intermembrane space</em> - Option D-.
Explanation:
There exist three proteinic complexes immersed in the internal mitochondrial membrane. These complexes have the electron transporters and the enzymes necessary to catalyze the electron transference from one transporter to the other. In complexes, I and III released energy by electrons provokes changes in membrane transport protein conformation. These changes make possible the protons transport against their concentration gradient, going from the mitochondrial matrix toward the intermembrane space. The protons concentrations difference between the matrix and the intermembrane space represents released energy.

<span>Australopithecus afarensis is hominin discovered in the Afar region in Ethiopia. He lived between 4 and 3 million years ago. The most famous fossil is named Lucy. Australopithecus africanus was dated as living between 3.3 and 2 million years ago. Homo habilis is much younger: 2.1 - 1.5 million years ago. Homo erectus is the youngest ( from 1.9 million - 70,000 years ago ). Answer: The specimen could belong to B ) Australopithecus afarensis.</span>
<span>Rats have a uterus comprising of the right and left cornua (horns) referred to as a bicornuate uterus. This way the rat can support multiple fetuses, this structure enables the rat to have multiple offspring. The uterus accepts eggs and supports the growing embryos development until birth. </span>
