Accepted Answer

Arthropods, which include insects, spiders, and crustaceans, make up the largest phylum in the animal kingdom with over one million known species. Echinoderms, such as starfish and sea urchins, are a smaller phylum with around 7,000 species. Annelids, like earthworms and leeches, are a phylum with around 17,000 species. Arachnids, such as spiders and scorpions, are a smaller subphylum within the arthropods.

Question 8

Accepted Answer

Cannibalism of the young occurs frequently in captivity, whereas in the wild, the mother usually protects her young until they are able to survive on their own. Option A is incorrect, as not all scorpions lay eggs; some give birth to live young. Option C is incorrect because the number of young in a clutch can vary, with some species producing over 30. Option D is incorrect because scorpions are not known to exhibit parental care.

Question 9

The gestation period for a scorpion is _____.&#10;A)between 16 and 42 days&#10;B)more than two and half years&#10;C)several months to a year and a half&#10;D)no less than seven weeks and no more than ten weeks

Accepted Answer

The gestation period for scorpions ranges from several months to a year and a half, making option C the best choice. Options A, B, and D are all incorrect because they either give a range that is too short or too long, or a set timeframe that does not match the gestation period of scorpions.

Question 10

An emperor scorpion habitat should be kept at percent humidity.&#10;A)65 to 75&#10;B)more than 90&#10;C)20 to 40&#10;D)less than 25

Accepted Answer

Emperor scorpions are native to tropical forests in West Africa, where humidity levels are typically around 70-80%. Keeping the habitat at 65-75% humidity will provide them the moisture they need without causing any health-related issues. If the humidity level is too low, it can cause dehydration or drying out of the scorpion's respiratory membrane, while if the humidity level is too high, it can cause respiratory issues and mold growth in the enclosure.
