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.
Answer and Explanation:
Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth
. The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting
. Even though fewer offspring are produced through this method, their survival rate is higher.
