Caenorhabditis elegans is a small, free-living soil nematode. The adults of this species grow to be about one millimeter in length (Wood, 1988). This organism acts well as a model organism because of the easy and inexpensive nature in which it can be grown (Jorgensen and Mango, 2002). Its short life cycle provides many advantages in biological and genetic research (Jorgensen and Mango, 2002).
C. elegans is typically grown in a laboratory setting on agar-filled petri dishes, or in a liquid medium (Wood, 1988). This animal feed on Escherichia coli, a bacteria commonly found in the intestine of warm-blooded organisms (Wood, 1988). It has a tubular body with a hypodermal wall and underlying muscle system around the organs. The adults typical contain about 800 somatic cells (Kimble and Hirsch, 1979). …show more content…

When the organism moves, it produces a sinusoidal wave motion in the dorsal-ventral plane (Alberts et al., 2007). The food for this animal is taken up by a muscular pharynx and is then pumped into the intestine, which is made up of about 30 cells and is lined with microvilli (Wood, 1988). About seventy percent of the three hundred neurons of C elegans are located in the head (Wood, 1988). The nervous system also includes sensory receptors and ganglia, along with dorsal and ventral nerve cords. The sense organs, which include chemoreceptors and mechanoreceptors, are arranged in two concentric circles around the mouth (Wood,

Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell.

Then we took turns to examine the C. elegans under the dissecting microscope. When looking C. elegans under the microscope w first need to identify which one is male, female, dumpy and hermaphrodites Male has zig-zag shaped tail and males tend to be smaller than females. Females have sharp, and point tails they tend to be mostly long. The dumpy C. elegans is round and short oval shape tail dumpy are tend to little fat than others. The last type of C. elegans are hermaphrodites are big and fat with point tails they are very similar to male C. elegans.

M. musculus are a common model organism because of the advantages of the similarities to humans. It is especially used for research within medicine and genetic research 15. G. gallus have long been used as a model organism, to model human diseases and for developmental biology 16. X. tropicalis, also known as the Western clawed frog are mainly used in research as a model organism to study early embryonic development and cell biology 17. D. rerio, also known as Zebrafish are used as a model organism within several research fields, toxicology and developmental biology are two examples 18.

The group hypothesized that if worms in a bottle had dirt, compost, oxygen, and a good environment they would survive, reproduce, and improve soil. The groups hypothesis was partially supported by this experiment. For one, most worms did not survive. By the end of the experiment 5 worms remained although the group started out with 27.

2a. If sunlight were to disappear almost completely, it would leave lasting effects on many organisms such as an earthworm, a shark, a maple tree, a saguaro cactus, or a teenager. While looking at an earth worm, the short term effects would be beginning to see more of the species during the day. Earthworms are nocturnal, so they live beneath the surface when it is daylight and come out once the sun goes down. Because of this in the long run, the earthworm species would eventually become overpopulated; they would be above the surface more, so they would have more time to reproduce.

Our chemo sensation is our ability to detect chemical stimuli. When food is chewed, the person unintentionally pushes air through their nasal passages. Through this process, we smell the food to which gives us a very large ability to process flavour. The area of a sensory cortex that refers to smell is placed in a similar area to the part of the sensory cortex that refer to taste. The smell is only activated when it hits the neurons.
