How do frogs and toads, as well as salamanders, typically protect themselves from predators? by injecting venom into the predator using teeth

by crawling or hopping to a safe place

by squeezing the predator to suffocate it

O by rolling over and pretending to be dead

by crawling or hopping to a safe place

Explanation:

Most Amphibians like frogs, road, salamander protect themselves from predator by hopping and crawling to a safe place because they have the ability to puff out and look bigger in the sight of the predator. They can also remain underneath in water quietly for a long time. For example frog secrete moisture which sometimes it is irritating to the predators and serve as a defensive mechanism.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
