Answer:
There are Five main compounds but our body need carbohydrate and protein more.
Explanation:
There are five major organic compounds that our body needs for normal metabolic processes. These are- Carbohydrates, lipids, proteins, nucleic acids and high energy compounds. organic compounds are involved in almost all biochemical activities that is related to metabolism. The organic compounds always contain carbon. Carbs act as the source of energy to the body. They converted to glucose, which used in cellular respiration. Lipids act as fatty acids. Proteins have a structural function like keratin in skin and hair. Nucleic acids are large organic compounds that store and process information at the molecular level inside the body cells. High energy compounds like ATP serves as a source of cellular energy.
Answer: cell membrane
such as water, micro-organism
physical process
simple diffusion, osmosis and filtration
such as potasssium permaganate in water,urea a liver waste diffuses from the body and the kidney help in filtering it out
physiological processs
active transport, phagocytosis and pinocytosis
such as soduim-potassium pump, exocytosis
Explanation: transportation in and out of cell is done in different ways listed above but a barrier to this movement is the cell membrane which is an outer covering of the cell. it protect the cell and only some materials can penetrate the cell membrane e.g micro-organism, water e.t.c. the various physical and physiological processes are the various ways substance cna be liquid, solid or gas are transported within or outside the cell e.g food
Quality of light is the limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deeper
Explanation:
When sun rays pass through the water in the oceans, they are quickly diffused and cannot penetrate very deep into the deep water layers. Remember that phytoplanktons are photosynthetic organisms and hence require sunlight to manufacture their own food. They, therefore, cannot grwo in deeper layers of the oceans. They are only found in the photic zone.
The quality of light is especially of most importance and hence the major limiting factor. Red light, of longer wavelength, and which is the major wavelength of light that is used the most by photosynthetic organisms, diffuses very fast than blue light when it passes through water. Therefore the more reason phytoplankton is found in the top ten feet of the ocean, rather than deeper.
