Fight for Equality essays
Fight for Equality essays The nineteenth century faced an abundance of hardships as well as triumphs and discoveries. The most significant issue faced during this time was the African Americans struggle to be equal. Equality was on every black man and womans mind during the nineteenth century and keeping them from being a success was on every white mans mind. Though it was a struggle, many black men and women stood up for what they believed in and made it happen. It is these determined black men and women that are responsible for opening Americas mind to accept people, no matter of race. There is no doubt that no other issue during the nineteenth century has had a more significant impact on the twentieth century and all centuries to come. African Americans were known as the working class. This is because blacks were only allowed to be farmers and work on plantations owned by white men. They worked the land and white men prospered from it giving the African Americans only pennies to live on each day (Straker 26). The white man would do anything to [keep] a Negro down (Straker 26). Not only were they given poor wages for hard work and poor rations to live off of, but they were also told they could not own land. The blacks began to educate themselves the best they could and the white man began to notice the success of African Americans and took away what the Fifteenth Amendment gave the black community; the right to vote. The Fifteenth Amendment made it illegal to deny blacks the vote but racists found ways around the amendment by creating poll taxes which they knew blacks could not pay and literary tests which they knew most blacks would not pass (Tindall and Shi 616). States began developing plans of their own to keep blacks from voting. In Mississippi the Mississippi Plan was developed which stated that voters must live in the state for two years and in the voting district for one year. They were not a...

Habits and Traits of Darkling Beetles
Habits and Traits of Darkling Beetles The family Tenebrionidae, the darkling beetles, is one of the largest beetle families. The family name comes from the Latin tenebrio, meaning one who loves darkness. People raise darkling beetle larvae, known as mealworms, as food for birds, reptiles, and other animals. Description Most darkling beetles look similar to ground beetles, black or brown and smooth. Theyre often found hiding under rocks or leaf litter and will come to light traps. Darkling beetles are primarily scavengers. The larvae are sometimes called false wireworms because they look like click beetle larvae (which are known as wireworms). Though the Tenebrionidae family is quite large, numbering close to 15,000 species, all darkling beetles share certain characteristics. They have 5 visible abdominal sternites, the first of which is not divided by coxae (as in the ground beetles). The antennae usually have 11 segments and may be filiformà or moniliform. Their eyes are notched. The tarsal formula is 5-5-4. Classification Kingdom: AnimaliaPhylum: ArthropodaClass: InsectaOrder: ColeopteraFamily: Tenebrionidae Diet Most darkling beetles (adults and larvae) scavenge on plant matter of some kind, including stored grains and flour. Some species feed on fungi, dead insects, or even dung. Life Cycle Like all beetles, darkling beetles undergo complete metamorphosis with four stages of development: egg, larva, pupa, and adult. Female darkling beetles deposit their eggs in the soil. Larvae are worm-like, with slender, elongated bodies. Pupation usually occurs in the soil. Special Adaptations and Defenses When disturbed, many darkling beetles will emit a foul-smelling liquid to dissuade predators from dining on them. Members of the genus Eleodes engage in a somewhat bizarre defensive behavior when threatened. Eleodes beetles raise their abdomens high in the air, so they almost appear to be standing on their heads, while fleeing the suspected danger. Range and Distribution Darkling beetles live worldwide, in both temperate and tropical habitats. The family Tenebrionidae is one of the largest in the beetle order, with well over 15,000 species known. In North America, darkling beetles are most diverse and abundant in the west. Scientists have described 1,300 western species, but only around 225 eastern Tenebrionids.
