<u>Answer:- </u> <em>Option a </em>radial symmetry
<u>Explanation:- </u>
Most of the organisms have can either of the two types of symmetry:-
1. <em>Bilateral symmetry</em>- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a <em>single</em> plane.
For e.g if you cut the letter M from middle vertically then you have two equal halves.
2. <em>Radial symmetry</em> - A body is said to be radially symmetrical if it can be divided into similar halves in <em>any</em> plane. This means that the organism has its body parts arranged around a central main axis.
The <em>cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.</em>
Answer:
1. Bring new alleles from DNA
2. Favor certain alleles
3. Creates new alleles from DNA
4. Randomly selects alleles
Explanation:
1. The zebra enters a separate population, bringing their unique makeup into a group with similar genetic makeup
2. The organisms with genes for shorter heights will eventually die off, favoring organisms with greater height
3. The snake's DNA changes, allowing it to create stronger venom
4. The deaths of the animals weren't planned or the result of greater genes.
