A dog breathes in oxygen and then releases carbon dioxide when he exhales. Conversely, a tree gives off oxygen and takes in carbon dioxide. So the breath of the dog sustains the tree while the output of oxygen for the tree sustains the dog.
Similarities: both originated from “protists” and they have similar cell structures.
Differences: plants use photosynthesis to make food, while fungi cannot. Fungi does not possess chlorophyll, which is a key part of the photosynthesis process for plants.
Answer: Platelets release a vasoconstricting substance called <u>SEROTONIN.</u>
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.
The correct answer is:
Option D: Evapotranspiration
Water is removed both from the plants and the soil. Evapotranspiration is a process by which the water is removed from plants and ground and is added back into the atmosphere. From ground, water is removed in the form of evaporation from the soil. And from plants the water is removed by transpiration. Hence the term Evapotranspiration.
