Answer:
The excessive alcohol consumption of the mother.
Explanation:
Alcohol consumption during pregnancy harms the developing baby, the foetus. This is because alcohol passes from the mother's blood to the baby's blood and this affects the growth of the baby's cell.
This causes severe damage to the cells of the brain and the spinal cord.
FASD - Fetal Alcohol Spectrums Disorder is characterised by growth and developmental problems and it can range from mild to severe.
Example is the baby having small head, narrow eye and behavioural problems later in life.
Answer:
A
Explanation:
All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.
The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).
The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
