Answer:
The scanning electron microscope allows the elaboration of an image in which the surface characteristics of the sample are reflected, thus providing sufficient information on the shapes, textures, and chemical composition of the constituents.
Explanation:
The scanning electron microscope uses electrons instead of light for imaging.
To achieve this, the team has a device that produces an electron beam that allows the entire sample to be illuminated and, through different detectors, the electrons that are produced from the interaction with the surface of the sample are later collected.

Plants with a primary root and little lateral roots that extend out from it have a tap root system.
A taproot system, generally found in dicotyledons, is made up a central, large pointed root and this is what is called the taproot.
Smaller roots branch off from the taproot and are known as lateral roots. The tap root is larger in diameter than the lateral roots. Tap roots generally grow much more deeply into the soil compared to fibrous roots.
Answer:
The answer is a taproot system.

The atmosphere is the blanket around the Earth, which regulates the Earth's temperature and protects from harmful rays. The biogeochemical cycles like the water cycle also take place in the atmosphere.
The two ways in which water enters the atmosphere are:
Therefore, the two ways in which water is added to the water cycle are transpiration and evaporation.
To know more about evaporation and transpiration, refer to the following link:

Explanation:
Answer;
Individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce.
Explanation;
-In Africa savanna more wildebeest are born than the environment can support. As a result over a period of years individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce. This is referred to as natural selection.
-Natural selection is the process where organisms with favorable traits are more likely to reproduce. In doing so, they pass on these traits to the next generation. Over time this process allows organisms to adapt to their environment.
As a result of having more wildbeest than the environment can support, over a period of years to come, it is only the ones that are able to adapt to the situation that will survive and give birth to young ones while those that are unable to adapt to the situation will die out. This phenomenon is called the survival of the fittest. Because there were more wildebeest than the food resources that are available, there will be competition and only those who can cope will survive and reproduce while others die out.
