How do organisms use oxygen
Organisms that use oxygen need it for cellular respiration, in which energy is released from glucose. Energy is needed by the organism for growth, mobility and reproduction.
Answer: Almost all living things need oxygen. They use this oxygen during the process of creating energy in living cells... Animals form other half of the oxygen cycle. We breathe in oxygen which we use to break carbohydrates down into energy in a process called respiration.

The definition of manipulated variable ?
A manipulated variable is an independent variable subject to the changes of an experiment to analyze its effect on a dependent variable. Simply put, the variable is modified to assess its influence over the experiment’s overall result. It’s called “manipulated” because it’s the one you can change. In other words, you can decide ahead of time to increase it or decrease it. In an experiment you should only have one manipulated variable at a time.

Building Polymers
Monomers are the building blocks of larger molecules called polymers. A polymer consists of repeating monomers bonded to each other with covalent bonds.
Use the drawpad to connect each monomer to its polymer.
Answer: I'm doing the same homework. I'm pretty sure that the 6 hexagons are the startch glucose. Try page 2
Explanation:
Each monomer is correctly connected to its polymer in the attached image in which amino acid is attached with protein, the nucleotide is connected to DNA, the fatty acid is attached to fat or lipid, and glucose or sugar is attached to carbohydrates.
Monomers are the basic unit or building blocks of larger molecules known as polymers. Polymers are made up of two or more monomers or long chains of monomers attached together.
The macromolecules are polymers and made up of their particular monomers:
Proteins made up of amino acids: In the protein structure there are many amino acids are joined together with help of peptide bonds and due to this, it is also called a polypeptide chain.Nucleic acid (DNA) is made up of nucleotides- nucleotide monomers bind together and form chains of the nucleotides.Fat made up of fatty acids: Fats or lipids are polymers made up of long chains of fatty acids,carbohydrates made up of glucose monomers: glucose or other monosaccharides bind together to form polysaccharides or carbohydrates.Thus, the correct answer is attached as the image.
