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.
Answer:
a.Feeding on conifers evolved earlier than feeding on angiosperms. Feeding on conifers evolved earlier than feeding on angiosperms.
c.Diversification of the angiosperms may have led to diversification of herbivorous beetles. Diversification of the angiosperms may have led to diversification of herbivorous beetles.
Explanation:
Biological evolution corresponds to the process of modification and adaptation of species over time. The current diversity of living beings is the result of processes of transformation and adaptation of species to different environments, constituting biological evolution. This can be seen in various spheres of biological life on our planet, and in the case of beetles and plants mentioned in the question above, the evolution of species richness and herbivorous beetles can develop the following information:
- Feeding on conifers evolved earlier than feeding on angiosperms.
- Diversification of the angiosperms may have led to diversification of herbivorous beetles.
Answer:
Sister chromatids separate from each other during anaphase of mitosis and the anaphase II of meiosis II. During the anaphase stage of mitosis these chromatids separate and one chromatid goes into each daughter cell. During cell division they are separated from each other and each daughter cell receives one copy of the chromosome.
