After a week with lots of rain, runoff has caused a large amount of fertilizer to wash into the ocean from the farms on the California Coast. This caused a bloom in phytoplankton. When these microscopic
creatures die after their short life, their decomposition creates an environment in the water with little
oxygen, making it toxic to mussels and crabs. Identify two organisms which may benefit from this decline
and two organisms (other than mussels and crabs) which may suffer. Explain why this advantage or
disadvantage would occur.

Organisms are classified, or grouped into categories, based on similarities in their characteristics and/or evolutionary relationships. the study of how organisms are classified is known as

An organ system consists of a group of organs that performs specific functions necessary for the survival of an organism. humans have eleven different organ systems: integumentary, skeletal, muscular, nervous, endocrine, circulatory, lymphatic, respiratory, digestive, urinary, and reproductive. discuss the function of neurons, the brain and the spinal cord within the human nervous system while explaining the interrelationship of each organ.

Cold case files recently began re-investigating an old murder case. the murder took place in the park; a young man, james, was hit over the head with a brick and killed. police suspected the jealous former boyfriend of james' wife, karen. whoever killed james may have washed their hands in a near-by bird bath as detectives found blood in the bird bath. since the murder took place before dna fingerprinting was available, the suspected killer, ronnie, went free. detectives are now reviewing the blood evidence using dna fingerprinting. based on the dna fingerprints of all possible suspects, who is james' killer?
