Every planet in our solar system has been visited by an unmaned spacecraft sent by the United States. The launch years are given in this order
- Venus (1962)
- Mars (1964)
- Mercury (1973)
- Jupiter (1977)
- Saturn (1977)
- Uranus (1977)
- Neptune (1977)
- Pluto (2006)
Some adaptations you would expect to see on plants growing in both biomes are Low-growing plants, Waxy leaves to protect against evaporation, Ability to grow in soils with very low nutrients and water, and The ability to quickly bloom and reproduce when conditions are right. Hope this helped!
The correct answer is C. Dilation, strong contractions, and delivery of the baby and the placenta
Explanation:
Labor and delivery is divided into three main stages: the first stage includes the latent phase in which cervical dilation begins (3 to 5 cm) along with mild contractions and the active phase in which strong contractions occur along with complete or almost complete dilation; the second phase is the fetus expulsion or delivery in which the cervix is fully dilated and the baby is born; and the third stage is the delivery or expulsion of the placenta that occurs as the placenta separates from the uterus and is expulsed through mild contractions. Thus, stages of labor and delivery are dilation, strong contractions, and delivery of the baby and the placenta.
Answer:
Yes your correct, there are populations of fruit flies.
Answer:
A. Species that remained after the extinction were able to radiate, new adaptations arose, and these adaptations produced the diversity seen today.
Explanation:
When species went extinct they also left niches that could be occupied by "new" species; new places to live, places to be filled in the food web and different relationships to be formed. The wide availability of resources made organisms to radiate leading to a "new" diversity of shapes, sizes, and lifestyles.
B. Species that have gone extinct were able to re-evolve from the ancestors that survived the extinction. If you are extinct you are gone forever.
C. Species that remained after the extinction were unable to speciate. Therefore, the number of species on Earth today is lower than the number of species present just before either extinction. The fossil record proves that species have changed over time and the diversity has changed over the history of Earth.
D. Species that remained after the extinction represented all of the lineages that were present before the extinction event. Therefore, extinction did not change the diversity of lineages. Again, the fossil record is evidence that lineages have changed over the history of the Earth.
