Use the system represented by the diagram above to design a controlled experiment about algae. Algae, shown below, are organisms, such as seaweeds, that live in water that perform photosynthesis (make their own food). During photosynthesis, oxygen gas bubbles are released from the algae. In the design of your experiment be sure to include the following: 1. A question about algae that you can investigate using the system shown in the diagram above. 2. Write a hypothesis for the experiment 3. Describe the independent variable and the dependent variable 4.Explain how the control group will differ from the experimental groups 5. Describe 2 factors that will be kept the same in all of the groups and explain why each factor will be kept the same 6. Explain how you will determine whether your hypothesis was supported or refuted by the data from the experiment

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
