The correct answer is A. Scientists reintroducing crested toads into the wild.
Explanation
Species Survival Plan is a conservation program promoted by conservationists and zoologists that specializes in those animals that are near extinct, endangered, or threatened. This program mainly aims to breed these species in captivity to ensure their future preservation and reintroduction to nature. According to the above, the effect that could be expected from the implementation of the Species Survival Plan in Puerto Rico with the crested toads would be the reintroduction of this species into the wild after being bred in captivity.
Because nitrogen is a key component plants use to make chlorophyll and the key component in amino acids which make protein
Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy.
Nitrogen is an important component of many essential structural, genetic and metabolic compounds in plant cells. It is also an elementary constituent of numerous important organic compounds including amino acids, proteins, nucleic acids, enzymes, and the chlorophyll molecule.
Of all the essential nutrients, nitrogen is the one that is most often limiting for crop growth. Nitrogen is the nutrient which normally produces the greatest yield response in crop plants, promoting rapid vegetative growth and giving the plant a healthy green color.
SI units are a modern form of the metric system.
D surface tension because, adhesion is sticking, b makes no sense for this question, and heat has nothing to do with it either, because it distributes it's weight throughout its legs so it doesn't sink (it doesn't weigh much so this works.)
Hope this helps don't forget to hit that heart :)
