The amount of carbondioxide in the atmosphere would greatly increase if there were fewer plants.
(Plants) is the answer.
The survival of the species is ensured by C. by protecting the fertilized eggs from predators. The protection provided by the male increases the hatch rate of the eggs, which means more young seahorses. The greater the number of hatchlings, the greater the likelihood that some will survive to adulthood and carry on the survival of the species.
The example that does not exhibit sexual selection is:
D. male elephant seals fighting over territory and potential female mates
The competition for territory is also one that helps the elephant seals survive. This is because a seal with a larger territory is likely to have access to a greater amount of resources, ensuring its survival.
Blood types A and B are similar to each other because they both have antigen on red cells.
Blood type AB has both A and B antigens on red cells.
Hope this helped! :)
