Answer:
Cnidaria
→ Organisms have specialized stinging cells
→ Two type of body plans exist - polyp and medusa
Porifera
→ Organisms lack symmetry
→ Adult forms are sessile
→ Organisms obtain food by filtering water
→ Phenomenon of alternation of generation is observed.
Explanation:
Cnidaria, also known as the coelenterata, is a phylum of mostly marine animals having about 9,000 living species. Some of them include the corals, hydras, jellyfish, sea anemones, sea whips, etc. They possess specialized cells known as cnidocytes ( also known as “stinging cells”). These cells can seen around the mouth and tentacles cnidarian. They immobilize their prey with toxins. These Cnidaria have two body plans and which are polyp and medusa.
The phylum Porifera are known as the pore bearers. It has about 5000 species. Their adult forms are sessile. They live permanently attached to rocks. They can under alternation of generation. They possess no organs in their bodies. Also, they lack symmetry. They can be referred t as filter feeders because they obtain food by filtering water.
Answer:
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes. The process relies on Watson-Crick base pairing, and the resultant single strand of RNA is the reverse-complement of the original DNA sequence. The pre-messenger RNA is then "edited" to produce the desired mRNA molecule in a process called RNA splicing.
Explanation:
Answer:
Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5). ... However, when eukaryotic cells are not dividing — a stage called interphase — the chromatin within their chromosomes is less tightly packed.
