Body of water

Osmosis: diffusion of water Diffusion: molecules to spread out in order to occupy an available space, without using energy. *diffuse from high to low. -The egg was placed into water and the egg expanded because of osmosis and diffusion. there was more water outside the egg so some of it had to go in. Active Transport:molecules spread against the concentration gradient. this uses energy, and requires help from carrier proteins. * moves from low to high.…

is a stable polymer, being resistant to water,…

An average person can survive in freezing water for only a limited amount of time, that time is a few minutes. As you are falling into the water lean back to to keep your head above the water. The cold water will shock you and make you gasp, but try to stay as calm as possible and attempt to get out. Turn to face the direction you came from, this is probably the thickest…

While you are swimming in the ocean, you feel like something touches your body. In few minutes, you feel very itchy and a burning sensation. You realize that you are had been stung by a jellyfish. Not all jellyfish sting. Some of them are not dangerous to humans. Different jellyfish carry different venom, the symptoms and treatment of the sting differs from one to the other. People should know how do these beautiful gelatinous creatures pack such a painful punch, how to treat if they sting and…

calcium carbonate. To eat, mussels suck in water through their gills. The water brings oxygen and food into the mussel. Food is separated and taken to the palps then into the mouth. In females, gills also serve as an incubation chamber for baby mussels. Mussels also have a circulatory system powered by a two-chambered heart and a digestive system including: a stomach, intestines, and an anus. A nervous system consisting of ganglia controls the mussels’ body (Anatomy of Unionid Mussels). Zebra…

The waters were calm. Quiet. I sat in my boat, soaking up the rays of the late August sun. I needed this boat ride, it 's been pretty stressful at work. Listening to the sounds of birds, the crashing of waves, and the smell of dew really brings a serene aesthetic. I felt like I was spinning slowly. My eyes were closed, and I just let my mind wander. The warm breeze pulled me in for a hug, and I could feel the gusts of wind travel its way into my clothes. I snapped out of my trance, and I…

the decomposition of hydrogen peroxide to form water and oxygen, which occurs spontaneously, but not at a very rapid rate. Write a balanced equation for this reaction. Label the reactant and the product. (Remember that catalase is not a reactant or a product and can be written over the arrow separating the reactant from the products.) I will help you with the equation. Catalase 2H2O2 ------------------------> 2H2O + O2 (g) (Hydrogen peroxide) (Water) (Oxygen) 2. Explain why, in your…

Coelenterata - Characteristics of coelenterata are as follows: Coelenterata are creatures that live in the sea although there are some who live in fresh water.Coelenterata included in the class of diploblastik. Exterior body composition has epidermal cells and in the inner layer of gastrodermis. Coelenterata have a difference compared to the porifera where although equally hollow but coelenterata has only one hole for all activities such as eating and as a disposal. Another feature is on the…

The barrel cactus is easily distinguished from other cacti because of its cylinder-shaped body. It is one of the largest cacti in North America reaching a staggering eleven feet tall. Running down the spines are 3-4 inch spines and on top are rings of yellow-green or red blossoms. Native Americans used to boil them into cabbage-like stews. They would also grind up the pulp and extract the water. Another plant native to deserts is the brittle bush. IT is a small deciduous shrub which grows as a…

the dye extracted from samples of magnetic bentonite clay and of charcoal through filtration. From the data collected in this experiment, it was found that charcoal was a more effective alternative to use as an absorbing agent in rivers to clear the water of harmful PAHs. INTRODUCTION…
