Answer:

Alcohol fermentation

Explanation:

When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration

One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.

Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture

This process is taken advantage of to brew beer and wine.

Which statement describes transform boundaries?
WARRIOR [948]
Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California's San Andreas fault is a transform boundary.

Explain how prokaryotes can reproduce sexually and asexually.  In this discussion be sure to explain how the genetic material fr
Alexxx [7]

Answer:

During the asexual reproduction, bacteria can divide simply by binary fission in which one bacteria first replicate its genetic material and the cell divide in two daughter cells which are identical to the parent cell.

Asexual reproduction does not allow genetic variation therefore to get genetic variation bacteria can use conjugation, transformation and transduction process.

In conjugation, bacteria gets extra genetic material from other bacteria through sex pills. In transduction the genetic material enters into the bacterial cell through the virus then bacteria incorporate this genetic material in its genome.

In transformation, bacteria takes up the extra genetic material from it's surrounding. Therefore conjugation, transduction, and transformation helps bacterial to gain variation like as in sexual reproduction.

The answer to your question is either drawbridge or scaffolding. I want to go with drawbridge because it has support and stands of for itself, so its similar to a stucture if that makes sense.
