I think the correct answer from the choices listed above is option A. When crossing-over takes place, chromosomes exchange corresponding segments of DNA. Corresponding genes on non-sister chromatids are exchanged at chiasmata. Hope this answers the question.
The answer is :
B. A eukaryotic cell's nucleus contains the DNA or the genetic material of the cell.
The DNA has the necessary information for the cell's construction and the control of the synthesis tasks done by the cell. The nucleus is protected by the nuclear membrane. It surrounds the nucleus with a membrane with many pores.
Explanation:
The nucleus is a membrane-enclosed organelle located in most eukaryotic cells. The nucleus is the largest organelle in the cell and includes most of the cell's genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it proceeds up just a small portion of the cell's overall DNA content. Inside its fully enclosed nuclear membrane, it contains the preponderance of the cell's hereditary material. This material is designed as DNA molecules, along with a family of proteins, to form chromosomes.
Chlamydia is a common sexually transmitted disease caused by a bacteria called chlamydia trachomatis which can affect both sexes. In some pregnancies, this disease can cause premature labor among women. Moreover, it can cause chlamydia-related diseases among babies such as eye and respiratory tract infections. It is also a leading cause of early infancy pneumonia and pink eye or conjunctivitis. Therefore, Chlamydia is the sexually transmitted disease that can cause the aforementioned abnormalities.
Answer:Chromosones!
Explanation: Chromosones contain the DNA for your entire body.
