Suggest a reason for the rather large energy excess available in the insertion of a deoxyribonucleotide into a growing dna molecule. (about three times as much energy as is necessary is available in the reaction dntp dnan → dnan 1 pyrophosphate.)
a. the excess energy is used to produce atp to be used as a energy source in the rest of the cell.
b. the very favorable forward reaction means that the reverse reaction is very unfavorable.
c. the extra energy is used to drive the reassembly of the two separated dna template strands.
d. the energy is used by dna gyrase to supercoil dna

For a to be healthy, it has to have lots of different kinds of plants and animals. all of the different types of plants and animals in an ecosystem. name four types of ecosystems from those listed in the video. b) c) d) most living things live here. all living things depend on how an ecosystem like a game of sticks? why should we build new buildings on existing land? name four extinct species from those listed in the video. b) c) d) the best way to wipe out a species is to the largest ecosystem in the world is this percent of the world is covered by water. how many of all species in the world live in the ocean? list five things you can do to increase biodiversity. b) c) d) e) how many species are we losing per hour?

Which organelles are labeled d, and what is one feature that distinguishes them from the other labeled organelles chloroplasts the only organelles that produce sugars from sunlight mosomes, only found in animal and bacterial cells centricles only found in animal cells mitochondra, the only energo-generating structures found in cells
