Answer:
The evolution of the organisms can be explained on the different evidences like biochemical evidence, molecular evidence, morphological evidence and fossil evidence.
The fossil evidence indicates the direct evidence of the evolution. The feather present in the dinosaurs is used as the insulation that provide the heat to the birds. Later on the crowding on the land forms leads to the adaptation of the flight in the dinosaurs.
There are several techniques that can be used in studying the brain of human beings such as magnetic resonance imaging, magnetoencephalography etc.
Some of the techniques that are used to study the structure of the brain and ita functions are:
- Electroencephalogram (EEG): This is used for the detection of electrical activity in the human brain. It helps in the detection of abnormalities that an individual can have in their brain.
- Magnetoencephalography (MEG): This is a technique that's used for investigating the activities of the human brain. In this test, sensors are used in the formation of an image regarding magnetic fields that are produced within the human brain.
- Magnetic resonance imagining: This is when radio waves that are computer generated and magnetic fields are used in testing the brain. This helps in providing images of the brain.
In conclusion, the above techniques are used in testing the brain in order to carry out further research on the person.

Answer:
A cell plate
Explanation:
A cell plate is a structure found in plant cells on the top and bottom of the cell. It is a perforated wall made of cellulose and it allows for substances to move in and out of the cell, as the outer most layer of a plant cell, the cell wall, is impermeable.
