Radiology is the filed that includes CAT (computerized axial tomography) scans and MRI (magnetic resonance imaging) scans as diagnostic tools.
Radiology is the science that uses x-rays or other forms of energy to create images for diagnosis. It can also be used for therapeutic intent. It has a variety of techniques such as x-ray imaging, ultrasound, MRI, CT scan and PET imaging. The acquisition of images is done by the radiographer or also known as radiologic technologist. These images are then interpreted by a diagnostic radiologist, a doctor who is trained to read or interpret the images and produce a report of their findings and impression or diagnosis.
The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
- Zygote: Fertilized ovum.
- Blastocyst: Cluster of cells that is the result of the zygote going through cell division.
- Embryo: Unborn human that is still developing, usually before the 8th week of gestation.
- Fetus: Unborn human in development after the 8th week of gestation.
Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

Answer:
An experimental group is a group that receives the variable being tested in an experiment. The control group is the group in an experiment that does not receive the variable you are testing.
Explanation:
Control group, the standard to which comparisons are made in an experiment. ... A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.
The control group would be the group you keep control as you would not change anything about it throughout the course of the experiment. The experimental group you would give the experimental drug to.
