Answer:
D. changing the DNA of a living thing to change its characteristics.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits.
C I believe because they are living so they are able to breath
30) is B bec it goin from a low to high concentration every time that happens it requiers ATP.
31)B bec think of a enzyme as a key and a lock only one key will work with one lock and not others. So you see B and the black shape on top of it fits perfectly with. B . Another shape would not. So if it was a different shape the enzyme would not recognize it. The key would not fit the lock.
32) is A it pointing arrows out of the cell so everthing need to go out cell A has more insde then out so think ATP as a force pushing it out. And B there more in then out so it can move out easily:
Photosynthesis and cellular respiration are very different processes, in
that they require completely different products to produce the
necessary chemical reactions. However, they are similar in that they
both result in energy production for the organisms they are part of.
It would possess the same value. Remember the atomic number of an element corresponds to the number of protons found in an atom of that element.
