Answer: Non-homologous chromosomes
Explanation:
The overall length of the chromosomes and the placement of centromere are the two factors that required to same within the two pairs of chromosomes these chromosomes are considered as homologous chromosomes.
The non-homologous chromosomes can be defined as chromosomes that do not have the same overall length and placement of centromere is also not same. These chromosomes do not belong to the same pair or do not appear in the same pair.
The time of replication and banding pattern varies considerably in the non-homologous chromosomes.
The right answer is A.
Euglena (euglenae) is a common genus of flagellate algae, typical of Euglenophytes, and often found in water (usually freshwater, but there are rare marine species) rich in nutrients.
Men as a multicellular organism can move not through flagella but through contractions of muscle cells. In addition, there are cells inside the body such as macrophages and neutrophils that can move thanks to pseudopodia.
B nitrogen. Nitrogen is a non-metal element that occurs most abundantly in the atmosphere, nitrogen gas (N2) comprises 78.1% of the volume of the Earth's air. It only appears in 0.002% of the earth's crust by mass. Compounds of nitrogen are found in foods, explosives, poisons, and fertilizers.
