Answer:
The main purpose of Negative staining is to study the morphological shape, size and arrangement of the bacteria cells that is difficult to stain. eg: Spirilla. It can also be used to stain cells that are too delicate to be heat-fixed. It is also used to prepare biological samples for electron microscopy.
Secondly, what are the limitations of simple staining? Disadvantages. It does not give much information rather than the morphological characteristics of bacteria. Through simple staining, we cannot classify a particular type of organism.
Regarding this, what is an example of a negative stain?
In a negative staining technique, an acidic, anionic dye is mixed with a cell sample. The dye changes the color of the background, not the cells, causing the cells to stand out. India ink is the classic example of a negative stain.
Answer:
I'm pretty sure it stops erosion because the roots of the plants hold the soil, so that the soil doesn't fall away as quickly.
Explanation:
<span>By the late 1960s, scientists had developed the theory of plate tectonics based on a range of new evidence. Technological advances had helped reveal that the ocean floor was not essentially flat, as once assumed, but instead was marked by 50,000-kilometer-long (31,000-mile), 3,000-meter-high (9,800-ft) ridges and 11-kilometer-deep (7-mile) trenches. Scientists found striking patterns related to these features. They found that the youngest oceanic crust is located nearest the mid-ocean ridge and the oldest crust is nearest the trenches. They also detected a pattern of alternating magnetic polarity along the ocean floor, which emanated from the ridge tops. These two pieces of evidence, coupled with the fact that volcanic activity and island-building occurred most commonly at ocean trenches, suggested that new crust was created at mid-ocean ridges and destroyed at ocean trenches. Scientists Harry Hess and Robert Dietz used this evidence to revive and expand Holmes' convection theory into the theory they called "seafloor spreading." Finally, Wegener's notion of continental drift was coupled with a mechanism that could explain the movement of tectonic plates.</span>
Answer:
Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
Explanation:
If glucose was no longer available, the effect o the processes below will be as follows:
- Lactic acid fermentation - decreases
- Pyruvate processing - decreases
- Citric acid cycle - decreases
- Electron transport - decreases
<h3>What is the importance of glucose in the body?</h3>
Glucose is a monosaccharide that plays an important role as the main fuel for the cell to produce energy.
Glucose is broken down in the process of glycolysis to produce pyruvate as well as the reducing equivalents, NADH.
Pyruvate , the breakdown product of glucose from glycolysis enters other biochemical, reaction pathways such as:
- Lactic acid fermentation,
- Citric acid cycle, and
- Electron transport
Therefore, a constant supply of glucose is required to keep the above processes continually functioning.
