Which macromolecule is lopsided? One end has only carbon and hydrogen, while the other end includes nitrogen and oxygen. Place a snapshot here, and use the annotation tools to point to each end.

This macromolecule is lopsided because one end has only carbon and hydrogen, while the other end includes nitrogen and oxygen. (2:23:33 PM)

4. It is important for biological molecules to have a great variety of sizes, shapes, and surfaces. Suggest some reasons that this is true.

It's important for biological molecules to have a great variety of sizes, shapes, and surfaces because it helps other biological systems and molecules easily identify and differenciate other biological molecules. (2:32:31 PM)

    The purpose of this lab is to examine cross sections from the leaves of C3 and C4 plants and to determine the morphological differences between them while relating those differences to their metabolism. In C3 plants the carbon dioxide is first incorporated into a 3-carbon compound. Their stomata are open during the day and photosynthesis takes place throughout the mesophyll cells. In comparison C4 plants, the CO2 is first incorporated into a 4-carbon compound. Their stomata are open during the day and photosynthesis takes place within the inner cells.…

    Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and phosphate molecule.…

    1. Explain how cells specialize to form specific tissue and organs. Cells specialize to form specific tissue and organs by stem cells being able to develop into every type of cell in the body and eventually recreate a person’s tissues. With organs, after you gather the cells which can be from the patient’s own organs you have to go towards how they grow and specialise. The cells need to be put in the right environment, and exposed to the forces that they would normally experience in the body.…

    A macromolecule is a molecule that contains any "large number" of atoms. There are four main different categories of macromolecules that make up our body: carbohydrates, lipids, proteins, and nucleic acids. (1) Carbohydrates are sugars that store and transport energy. (2) Lipids also store energy and also are signalling molecules. (3) Proteins are linear chains of amino acids that help with the structure, function, and regulation of the body’s tissues and organs.…

    Prokaryotes do not have a developed nucleus instead the cell has a nucleoid which is also known as a nuclear bound and it lacks the cytoplasm membrane. Prokaryote structures consist of the flagella, pili, and capsules. The flagella is placed down in the plasmatic membrane and cell wall. The flagella moves by whirling its “tail” like a propeller on a boat to transport from place to place.…
