Answer:
The correct answer is - Polymer (macromolecules), monomer (building blocks
Explanation:
Polymers are comparable to the train as polymers are made up of several monomers linked together to carry more but can be removed from the polymer if required similarly the train cars that are comparable to the monomers or building block are joined together but can be taken off.
Macromolecules are polymers that are made up of joining monomers together and makes large molecules. Macromolecules like carbohydrates are made up of monosaccharides as monomers, proteins are made up of amino acids as monomer or building block, lipids are made up of fatty acids and nucleic acid are made up of nucleotides.
Answer:
Darwin was able to explain evolution with evidence, something Lamarck did not do.
Explanation:
Lamarck and Darwin both were scientists who tried to understand the concepts of evolution. Lamarck's theory of evolution was based upon how living organisms vary during their lifetime, and after that they pass these changes to their offspring. While on the other hand Darwin's theory was very much based upon evidences and practical explanation that is why his theory became accepted and Lamarck's wasn't.
Cellular respiration, on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy. It does not require the presence of sunlight and is always occurring in living organisms. Cellular respiration takes place in the mitochondria of cells.
Answer: The correct answer is
No, because NaCl is Ionic
Explanation:
NaCl can pass through the cell membrane because it is Ionic and separates into Ionic components Na+ Cl+.
Cell membrane are phospholipids bilayers and have hydrophobic tails and face inside of the cells . The fatty acids tails are non polar and only non polar substances can pass through it but salts is a polar molecules because it is an ion and cannot pass.
