percent of all species are alive today are invertebrates. Invertebrates are united more by what they lack (a backbone) than by shared characteristics. Invertebrates include animal groups such as sponges‚ cnidarians‚ flatworms‚ molluscs‚ arthropods‚ insects‚ segmented worms‚ and echinoderms as well as many other lesser-known groups of animals. Scientists are still uncertain exactly how the first invertebrates evolved. Most experts agree that the first invertebrates evolved from single-celled‚ food-eating

The first law of Ecology states‚ “everything is connected.” Meaning each species depends on another species for survival. Humans for instance‚ depend on the survival of animals and plants to literally feed our ever growing population. Our diet comes down to small‚ overlooked organisms such as the honeybee. Without honeybees‚ the majority of fruits and vegetables would be diminished. Albert Einstein supposedly once said‚ "If the bee disappears from the surface of the earth‚ man would have no more

The honey bee is a fascinating and important figure for pollinating flowers‚ fruits‚ and vegetables‚ they help other plants grow by transferring pollen between the male and female parts‚ supporting plants to grow seeds. Honey bees are insects have have three segments of their body‚ which six of them are visible and the other three parts include: legs‚ singer‚ and antenna. Honeybees have a exoframe‚ which is stiff and contains an overlay of wax‚ but honeybees do not have internal bones compared to

INTRODUCTION Extracts from black pepper discourage insect pests from laying eggs on leaves and pose lower risk to humans and the environment than other pesticides‚ a University of Ottawa researcher says. The more susceptible species were pine sawflies‚ which are passed on ornamental plants and caterpillars such as the eastern tent caterpillar Black Pepper worked better when insects are soft-bodied during the larval stage because the chemical is able to penetrate

Abstract In this experiment‚ the preferences of mealworms towards lighted and dark environments were tested. The main question posed was whether the behavior of the mealworms would be affected by the variable of light‚ and whether they would move towards or away from the light source (taxis). We placed ten mealworms into two adjoining containers and tried to simulate the effects of above ground and underground by exposing the mealworms to minimal amounts of light in one of the containers (underground)
