Answer:

The correct answer would be "self-replicating RNA molecules".

Self-replicating RNA is considered as the first genetic material that evolved on earth.

RNA had capabilities of self-replication as well as catalysis due to which it was efficient to make copies of itself to be passed on to subsequent generations.

The catalytic property enables it to catalyze all the reactions necessary for its survival.

DNA is believed to evolve from RNA which enhances the stability of the genetic material.

<span>The correct answer is self-replicating RNA molecules.

The first to be known genetic material on earth was self-replicating RNA molecules. Self-replicating RNA replicates and store genetic information, for example, RNA enzymes, protein enzymes.

Answer:

a. Nucleolus: The nucleolus refers to a composition, which develops with the assistance of the nucleolar organizer region present in the eukaryotes. It constitutes protein and ribosomal DNA and is a location where the generation of ribosomes takes place.  

b. Centromere: The prime function of the centromere is to function as the point of attachment for sister chromatids and is a place where the attachment of chromosomes and spindle fibers takes place. The differentiation of centromere takes place at the time of mitosis and meiosis II, which helps in the distribution of chromosomal substances to the daughter cells.  

c. Ribosome: The ribosome refers to the composition where different forms of RNAs, enzymes and other components help in the alignment of the primary sequence of a specific protein.  

d. Chromatin: Chromatin constitutes the genetic information, which helps in sustaining hereditary information and generation of a phenotype.  

e. Centriole: The centriole refers to a cytoplasmic composition, which via the help of spindle fibers assists in the migration of chromosomes at the time of meiosis and mitosis, mainly in the animal cells.  

f. Mitochondria: The mitochondrion refers to a membrane-bound composition situated in the eukaryotic cytoplasm. It is the place where the production of huge amounts of ATP takes place via the process of oxidative phosphorylation.

Answer:

The correct answer is : ciliophora is the phylum.

Explanation:

Ciliophora is a phylum which comprise organism of ciliates groups. Ciliates are protozoans found in aquatic or near aquatic conditions. These organism have egg like body in shape however some have different shape. The major characteristic feature is cilia, a hair like structures present on the body of these organisms.

They have cell with cytoskeleton, cilia, two different types of nuclei.The hair like structure called cilia used for collecting food and movement or locomotion.  

Thus, the correct answer is : ciliophora is the phylum.
