Urochordates, commonly known as sea squirts have a larval stage that resembles a chordate.

What are Urochordates? Give the characteristics of it.

Ascidians (sea squirts) are a common term for the Urochordata, also known as the Tunicata. The body of an adult tunicate is fairly simple. While possessing all the characteristics of a chordate, including a notochord, a dorsal nerve cord, pharyngeal slits, and the larva of many tunicates swims freely and lacks only these characteristics. Ascidia, Salpa, and Doliolum, for instance.

Characteristics features of Urochordata:

1. The grownups are anchored to the foundation.

2. It is also known as "Tunicate" because an adult's body is covered by a tunic formed of tunicin, a cellulose-like substance.

3. The notochord only appears in the larval stage and vanishes in the adult.

4. In adults, a dorsal ganglion takes the role of the nerve cord that is present in the larva.

5. The larva can migrate and changes into a different animal.

Normally, wild violets have yellow petals with dark brown markings end erect stems. Imagine you discover e plant with white peta

Wittaler [7]

Answer:

It is fascinating to observe two distinct characters presented by the same plant. The inheritance of this plant can be determined easily by crossing the pure violets exhibiting yellow petals with dark brown marking and erect stems with violets exhibiting no markings, white petals, and prostate stems.

The F1 progeny will originate as a hybrid of the two characters. These F1 plants will then be crossed between themselves and the F2 progeny would be clearly evaluated. If the F2 plants come in the phenotypic ratio of 3: 1, then it would indicate the pleiotropic effect of the alleles found in a single locus. If any other combinations arise post crossing, it would indicate that the non-wild type phenotype is because of many distinct mutant genes.

Which would probably have the greatest effect on a protein's function

Nonamiya [84]

Answer:

Tertiary Structure

Explanation:

Proteins are made up of amino acid units. The four types of protein structure are primary, secondary, tertiary, and quaternary.

From the given options, the greatest effect on a protein's function is caused by tertiary structure because it has branched structure and have several side chains. These side chains can interact in different ways and can change the effect on a protein's function.

Hence, the correct answer is "Tertiary Structure".
