Mutations in what class of genes have probably been responsible for many of the changes leading to the great diversity of life e
vampirchik [111]
Yes but cells also help get life to where it is right now and cells will also be changing genes connect with who we are and what we are and without those genes and cells we wouldn't be who we are today. genes do regulate mitosis but not for aerobic respiration genes give use our characteristics like girl,boy. DNA does help repair genes like per say you got a scrape on your leg or arm the DNA would clot so that the bleeding would stop and that would cause it to scab over.

9. a) How does hydrogen bonding help the transport of water in plants?
grigory [225]

Answer:

Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.

Explanation:

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
