All organisms consist of structural units called cells; some contain a single cell (unicellular) and others contain many units (multicellular). Multicellular organisms are able to specialize cells to perform specific functions. Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.. All living things are made up of cells. In organisms, cells work together to form tissues and organs that are specialized for particular body functions.

Round (R) seed shape is dominant to wrinkled (r) seed shape in pea plants. If an RR plant is crossed with an rr plant, what is t

melamori03 [73]

Answer:

The correct answer is b. All round seeds

Explanation:

If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.

R R

r Rr Rr

So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.

Despite their seemingly simple anatomy and radial symmetry Sea urchins and sea star are a type of deuterostome, closely related to the chordates.

What are the characteristics of deuterostome?

Animals classified as deuterostomes share a common embryonic development.

The first opening during development known as the blastopore changes to the anus in deuterostomes while the mouth changes in protostomes.

They have a coelom, which forms as a result of enterocele (coelom from the digestive tract).

These creatures include the following,

- Chordata,

- Echinodermata,
