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.

For example, many lepidopteran species (i.e., butterflies) include a caterpillar juvenile stage. To reach the adult stage, the juvenile stage has to go through metamorphosis, where its adult form is strikingly different from its juvenile form.

I attached the image related to your concerned question. 

In theory, the part of the brain that is responsible for the sleep wake cycle is the hypothalamus; specifically, the ventrolateral preoptic nucleus of the hypothalamus. In the image, the location of the hypothalamus is pointed by the green square.
