Limpets (Patella vulgate) live in algae rich environments on rocky shores. They feed on the algae and try to defend areas where algae grow against other limpets and other species that are competing for the food source (e.g barnacles and mussels). Limpet shells

What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.

Carbohydrates: any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones, or change to such substances on simple chemical transformations, as hydrolysis, oxidation, or reduction, and that form the supporting tissues of plants and are important food for animals and people.

During my walk in Oral Robert University, I have discovered new adventures and paths that lead me to believe Jesus is and will always be the best thing that ever happened to me. In my discipline, which is biology, I have seen and experience many ups and downs, I have heard the mentality of some of my school mates when they tell me their view between biology and Christianity. Thankfully I never doubted about my beliefs. I am thankful I did not mix my knowledge of biology and my faith with Jesus in a way that I would have to stop believing either one. I love biology, but I love Jesus the most. Instead, biology did in fact helped me realize the amazing creation of our God behind every part of science. How do we show that to the rest of biologist out there? It is important to switch the presupposition that goes against or in different ways to Christianity, to ultimately reveal the truth to even those who are strongly opposed to Christ in the scientific world; introducing a Christian Theism world, and finally guide their beliefs and actions towards the living Christ.

1) Leaves- Main organ for photosynthesis and transpiration. A flattened, typically green and blade-like structure of a higher plant.

For my AP biology summer assignment, I chose to do “Decaying Foods”. In my project, I used a slice of whole wheat bread and an apple slice. Throughout the fourteen days, I made observations on the plates every two hours beginning at 10:45 AM. On Day One, Plate A was in the refrigerator, Plate B was in the closet, and Plate C was on the windowsill, all starting out fresh. As the day progressed, objects on Plate A remained in their natural state, on Plate B the crusts of the bread became hard, and the apple slice was brown and dried out , and the apple slice had become hard and the bread felt toasted on Plate C. On Day Two, Plate A remained the same, Plate B had hard bread and the apple slice was wilting in the core and Plate C’s bread was cracking

Sirens Rocks is a rocky shoreline located along Wellington 's Southern Coastline inbetween Island Bay and Owhiro Bay. Along the shore there are many different species distributed within the intertidal zone. During my visit to Siren 's Rocks i was able to witness many of these species, including 2 species of true limpets called Cellana Denticulata and Cellana Radians. Cellana Denticulata, commonly known as the "denticulate limpet ' is a marine gastropod belonging to Nacellidae family. its cone like shell possesses a brown or grey toned exterior with a paler bluey white interior. In order to feed, a patellaogastropoda (scientific name for true limpet) such as C.Denticulata uses a ribbon like tongue with rows of teeth to scrape algae of the substrates they live on. Cellana RAdians are also a gastropod Mollosc, also belonging to the Nacellidae family. (Nacellidae means a "taxonomic family of sea snails or true limpets, in the clade Patellogastropoda") This means that like the Denticulate Limpet, Cella Radians feed by grazing algae with thier radula. They possess a lightish grey shell with darker ribs but a generally smooth shell unlike the Denticulate limpet. both limpets are found on the rocks or other hard substrates, usually on the southern side. Subtidal limpets such as the denticulate limpet and radiate limpet are often covered in a layer of green algae also. This makes them harder to spot as they

The aim of this investigation is to look at the distribution of the ornate limpet, (Cellana Ornata) and the radiate limpet (Cellana Radians) on the rocky shore. We went to the rocky shore of Sirens rocks between Island Bay and Owhiro Bay, on Wellington’s South Coast. We are studying how our chosen organisms affect each other’s distribution patterns. We sampled in the low tide zone, mid tide zone, and high tide zone. The rocky shore we explored was 80 metre long, rocky terrain, bare rock platforms with rock gulley’s.
