Option C is not correct because it suggests that internal gills develop before external gills during the metamorphosis of the toad. However, the opposite is true - external gills develop first, followed by internal gills. This is because external gills are necessary for respiration in the aquatic environment where the tadpoles live, while internal gills develop later as the tadpole begins to transition to a more terrestrial lifestyle. Therefore, option A is the correct answer, where external gills develop before internal gills.

Tapeworm
Centipede
Crayfish
Shark
A. The tapeworm is not metamerically segmented. Tapeworms belong to the phylum Platyhelminthes, which are characterized by a bilaterally symmetrical, flattened body without any segmentation. In contrast, centipedes, crayfish, and sharks are all metamerically segmented animals, meaning they have a body composed of repeated segments with similar organ systems. Centipedes belong to the phylum Arthropoda and have a segmented body with one pair of legs per segment. Crayfish belong to the phylum Arthropoda as well, and have a cephalothorax and an abdomen, both of which are made up of segments. Sharks belong to the phylum Chordata, and although their body segments are less apparent, they are still considered metamerically segmented due to their internal structure. Therefore, option A is the correct answer.
Similar organism that are found in the same habitat
Similar organism eating the same food
Different organisms in the same habitat
Similar organisms that breed in the same habitat
C. A population is defined as the collection of different organisms of the same species that are found in the same habitat and can interbreed to produce viable offspring. Therefore, option C is the correct answer. Option A is incorrect because a population includes organisms of the same species, not just similar organisms. Option B is incorrect because organisms in a population may eat different types of food within the same habitat. Option D is incorrect because organisms in a population may breed with other populations of the same species, not just in the same habitat.
