Answer:
A protist
Explanation:
In the given question, the characteristic of an unidentified organism are given which are:
1. The organism is unicellular and autotrophic which means that it is a producer and belongs to a plant like organism.
2. The membrane bound nucleus means that the organism is an eukaryote.
The organism is thus an unicellular, autotrophic and an eukaryote could be a species of algae which is considered a protist. The protists are the organisms which shows characteristic of the ukaryotes but are not considered true plants and animals.
Thus, a protist is correct answer.
A new DNA strand elongate only in the 5' to 3' direction during DNA replication because the "polarity of the DNA molecule prevents addition of nucleotides at the 3' end" .
DNA replication occurs in the 5' to 3' direction. DNA polymerase can only add nucleotides to the 3' OH group of the growing DNA strand, this is why DNA replication occurs only in the 5' to 3' direction.
DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered. Consequently, synthesis proceeds immediately only along the so-called leading strand.
Hence, the correct answer will be option (B)

Color blindness is a recessive x-linked trait in humans. In a family where the mother is color-blind, and the father is normal, the probability of their having a color-blind son is 100%.
Color blindness is a recessive x chromosome liked recessive disease which is more prone in males than in females. As the mother is color-blind she has both the alleles of colorblindness while the father is normal with both x chromosome and y chromosome normal.
So if the parents have a boy, he will always receive an x chromosome with colorblindness gene from the mother and a normal y chromosome from the father always. Thus, the probability of having a colorblind boy will be 100%.

Their mass because it can let you know their weight and size
The appropriate response is C. Prokaryotes are unicellular life forms that need organelles or other interior film bound structures. In this manner, they don't have a core, be that as it may, rather, by and large have a solitary chromosome: a bit of roundabout, twofold stranded DNA situated in a territory of the phone called the nucleoid.
