scientists have created dogs that are twice as strong as they would be naturally, through genetic engineering of the myostatin protein. the myostatin protein inhibits muscle growth, deleting this gene allowed the dogs to grow more muscular. the process used on the dog embryos could help prevent some human genetic disorders that affect the muscles of humans, like muscular dystrophy (a degenerative muscle disorder) based on their success with the two dogs, scientists stated it was possible for humans to be similarly genetically modified

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

carbon atoms, hydrogen, oxygen, and nitrogen.

i won't lie i don't know so go online and ask google thats what i do
