Answer:
Plant cells have cell walls.
Explanation:
While both plant cells and animal cells have cell membranes, only plant cells have a cell wall, the hard outer shell of the cell.
Answer:
plant cells have cell walls and chlorophyll
Explanation:
animals do not have cell walls or chlorophyll so if the cell has either those two things, you know it's a plant cell.

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.

I
Answer:
sodium chloride, magnesium, sulfate, calcium, potassium, as well as dissolved gases, including nitrogen, oxygen, and carbon dioxide.
Explanation:
Ocean water little a lower freezing point, and higher electrical conductivity due to salt.
What is ocean water?Seawater has special qualities such as being salted, having a little lower freezing point than freshwater, being significantly denser, having a lot higher electrical conductivity, and being slightly basic.
The two ions that are most often found in seawater are sodium and chloride. Over 90% of the dissolved ions in saltwater are made up of chloride and sodium.
Seawater has a salinity of around 35 parts per thousand of salt. 96.5 percent of seawater is made up of pure water, 2.5 percent salt, and minor quantities of dissolved inorganic and organic compounds.
Therefore, due to salt ocean water has higher electrical conductivity and other properties.

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.

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.
