From one original cell, four genetically unique daughter cells, each with 23 nonreplicated chromosomes, are produced at the conc
lukranit [14]

Answer:

True

Explanation:

Meiosis is a type of cell division that occurs in gametic cells. In this cell division, one cell is divided into four cells and the chromosome number is reduced to half therefore it is also called reduction division.

During meiosis crossing over occurs between homologous chromosomes that allow the exchange of genetic material between them that results in the formation of genetically unique daughter cells.  

In spermatogenesis during the first meiosis division, the homologous chromosomes get separated into two daughter cells reducing the chromosome number by half and during second meiotic division sister chromatids separate into two more cells. Therefore four genetically different cells are generated.

Crazy boy [7]
The correct answer would be stress tests. These are performed to assess the adequacy of the amount of oxygen getting to the heart muscle during exercise and at rest. With this, the absence or presence of a heart disease can be indicated. This is a common procedure done in Cardiography and Cardiovascular Monitoring Services. During this test, the patient is asked to do exercises usually using a treadmill while the patient is hooked on an EKG or electrocardiogram machine. As one exercises, the doctor would monitor the heart rate reading the systole and the diastole. There are also imaging tests to be able to capture pictures of the blood flow in the heart.
