Nitrogen is not a product of photosynthesis
Answer:
Its B because if it reacted chemically it wouldn't be considered a physical property since its changing on the "inside"
The correct answer is this one: "C) Nnew = Nold + 2." A student is studying a process in which a diploid cell becomes haploid. The CORRECT mathematical model for the process if Nnew is the number of chromosomes in the haploid cell and Nold is the number of chromosomes in the diploid cell is this: <span>new = Nold + 2
</span>
Here are the choices.
<span>A)
Nnew = 2·Nold
B)
Nnew =
Nold
2
C)
Nnew = Nold + 2
D)
Nnew = Nold × 2</span>
<h2>Gram Negative and Positive Bacteria</h2>
Explanation:
- The cell wall of <em>gram-positive bacteria is a peptidoglycan macromolecule </em>with joined adornment molecules, for example,<em> teichoic acids, teichuronic acids, polyphosphates, or sugars</em>
- <em>Gram-negative bacteria</em> organisms are not destroyed by specific cleansers which easily <em>kill Gram-positive bacteria </em>
- Surface displayed proteins on microbes play key role in <em>pathogenesis </em>as they elevate bacterial attachment to have tissues, acquisition of essential nutrients, evasion and suppression of<em> immune response and host cell entry</em>
