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.

I think the best answer is D
The answer is Both features have a recessive phenotype in these offspring.
An individual's phenotype is defined by their genotype and expressed genes, as well as apparent traits such as hair colour or type, eye colour, body shape, and height. It is determined by the genotype, but it is also modified by environmental circumstances.
What is genotype?
- The genotype of a person can reveal their genetic makeup.
- It determines which qualities will be expressed.
- Organisms with similar appearances do not share the same genotype.
- Biological tests can be used to determine a person's genotype.

Answer:
Explanation: Well, In the first few days after a fracture/breakage in the bone, the body forms a blood clot around the broken bone to protect it and deliver the cells needed for healing. Then, an area of healing tissue forms around the broken bone. This is called a callus, (It joins the broken bones together)
1. Passage of a sperm through the corona radiata of the oocyte.
2. Penetration of the zona pellucida.
3.Fusion of the plasma cell membranes of the oocyte and sperm. after fusion the sperm head and tail enters the oocyte but plasma membrane of sperm doesn't.
4. Completion of the second meiotic division of the oocyte. this creates female pronucleus and polar body 2.
5. Formation of the male pronucleus (nucleus of sperm enlarges)
6. Breakdown of the pronuclear membranes and restoration of diploid number of chromosomes.
