Answer:
Herbaceous stems lack woody tissue and growth rings unlike woody xylem. Wood is a composite of cellulose fibers which require the the process of phloem in the bark to contain nutrients unlike herbaceous stems that rely on xylem that contains vessel and vascular elements.
Explanation:
Answer:
The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP
Explanation:
Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles. Many also have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1–5.0 µm.
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. Eukaryotic cells tend to be 10 to 100 times the size of prokaryotic cells.
The answer is B.
The most closely related organisms will have the same genus, which is the first part of an organism's name. Since both organisms in option B start with Sylvilagus, they are most closely related.
Answer:
The answer is B. Van der Waals forces are weaker than ionic and covalent bonds.
Explanation:
In general, if we arrange these molecular forces from the <u>strongest to weakest</u>, it would be like this:
<h3>Covalent bonds > Ionic bonds > Hydrogen bonds > Dipole-Dipole Interactions > Van der Waals forces</h3><h3 />
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the <u>protons and electrons causing an electro-static force</u> which results to the strong bonds. An example would be <em>Sodium Chloride (NaCl)</em>, which when separated is <em>Na⁺</em> and <em>Cl⁻</em>.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through <u>residual molecular attractions when molecules pass by each other.</u> It doesn't even last long due to the <u>uneven electron dispersion</u>. It can be made <u>stronger by adding more electrons in the molecule</u>. This kind of molecular bonds appear in <em>non-polar molecules</em> such as <em>carbon dioxide</em>.
