Answer:

Presence or absence of cilia/stinging cells.

Numbers.

Retractability.

Number of cells.

Explanation:

Apart from size difference, tentacles in Cnidaria and Bryozoa differs such that:

  • <em>The tentacles in Cnidaria have no cilia surrounding them while those of Bryozoa are ciliated. Instead of cilia, the tentacles in Cnidaria have stinging cells.</em>
  • <em>Tentacles in Cnidaria are fixed in number while the number may vary in Bryozoa.</em>
  • <em>Tentacles in Cnidaria are often retractable while retractability is not possible in Bryozoa.</em>
  • <em>Cnidaria tentacles are made up of multiple cells while those of Bryozoa are made up of single cells.</em>

Answer:

The tentacles of Cnidaria is madeup of more than one cell while tentacles of Bryozoa have a single cell. Tentacles of Bryozoa is covered with cilia while tentacles of Cnidaria consist of stinging cells.

Explanation:

Phylum Cnidaria belongs to kingdom animalia which consists of about 11000 species. The members of phylum Cnidaria are aquatic organisms while phylum Bryozoa also belongs to kingdom animalia and also lives in water. Both members of the phyla Cnidaria and Bryozoa are invertebrates and uses tentacles for capturing food.

nexus9112 [7]

Answer:

<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring  will all be heterozygous and increase chances of future variation.</em>

Explanation:

The cross for the offsrings that will be produced by F1 generation is shown below:

         a          a

A      Aa       Aa

A      Aa        Aa

As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.

A cross between the F1 generation will give the following results:

         A          a

A      AA      Aa

a       Aa      aa

This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.
