A sunflower is an angiosperm, and a gingko is a gymnosperm. Which best describes the life cycles of sunflowers and gingkoes? I.
dalvyx [7]

The correct statements are I, III and IV.

An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms include a large group of herbaceous plants, grasses, shrubs, and the majority of trees. While gymnosperms refer to the plants that exhibit seeds but not safeguarded by any kind of fruit or ovary. It includes the cycads, gingko, and conifers.

Both the angiosperm (sunflower) and gymnosperm (gingko) are seed-bearing plants. However, the seeds of a sunflower are safeguarded by a flower or fruit, while for the gingko, there is no mechanism like that, i.e, there is not any kind of protection. Additionally, sunflower exhibit phenomenon of double fertilization, which is not witnessed in the case of gingko.

When a parental cross is done between rabbit with albino rabbit, having genotype cc and with Himalayan phenotype that have a genotype of chch, it results in the production of F1 rabbits having all the Himalayan phenotype.

And if the F1 rabbits are now crossed, three-fourth of the F2 offspring have the Himalayan phenotype. The distinctive fur pattern and the unstable allele of hypomorphic ch is caused by the temperature of the surrounding.
