D. a viral disease because it is known and unknown and spreads.
Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
Hhv-5 infectious in pregnant women can be particular concern because this virus can be teratogenic.
<h3>
What is teratogenic?</h3>
- Teratology is the study of aberrant physiological development across the whole life cycle of all species, including plants.
- Dysmorphology is a branch of medical genetics that focuses on the classification of congenital deformities.
- Teratogens are substances that, when exposed to a pregnant woman, may result in physical or functional abnormalities in the human embryo or fetus.
- Such substances include, for example, alcohol and cocaine.
- A teratogen is an agent that increases a baby's risk of developing a birth defect or can actually cause one.
- They are items to which a mother might be exposed while expecting.
- Teratogens can result in neural tube abnormalities like spina bifida during this time.
- Throughout the entire pregnancy, certain organs are vulnerable to teratogens.
- The baby's brain and spinal cord are included in this.
- Alcohol can be harmful at any point during pregnancy since it has an adverse effect on the brain and spinal cord.
