Like their relatives the honey bees‚ bumblebees feed on nectar and gather pollen to feed their young.The blood or hemolymph‚ as in other arthropods‚ is carried in an open circulatory system.[3] The body organs‚ "heart" (dorsal aorta)‚ muscles‚ etc. are surrounded in a reservoir of blood‚ and pulsing contractions of the tube-like dorsal aorta create a weak circulatory force.

the spider’s aggressiveness towards his victims. The Widows have an immense appetite‚ eating anything that lands in their sticky web. The Black Widow spiders have been seen “eating scarab beetles heavy as pecans” they have also been seen eating “arthropods of various sizes”.

Darwinism; Darwinism is the theory of the evolution of species by natural selection advanced by Charles Darwin. I’m reading the book “Darwin’s Doubt “ by author Stephen C. Meyer to get insight on the first discovery of fossils and how the sudden appearance of these unique animal life supports the theory of intelligent design to be the best explanation about the origin of the Cambrian animal and the biological input to produce them . I am also exploring the flaws that are stated in the Darwin Theory

David Kennedy Evolution Group 4 9/22/13 Lab 1: Insect Diversity and Evolution Introduction: Insects dominate the Earth with vast diversity and number of species. They are arthropods that have articulate appendages‚ a hard exoskeleton‚ compound eyes‚ and an open circulatory system with a dorsal heart. Insects have large populations in many habitats‚ even urban environments such as Chicago. Insects are close relatives to Myriapoda‚ Chelicerata‚ and Crusacea organisms (Hoffmann 63). They are incredibly

The Swiss chemist Paul Müller was awarded the Nobel Prize in 1948 f5or his discovery of the high efficiency of DDT as a poison against several arthropods. DDT was also used in the second half of the World War 2‚ because it was against the mosquito that spread malaria and lice that carry typhus. After the World War 2‚ people discovered that it could also be used for farming. DDT could terminate
