Select the layers of Earth that are completely solid. A. crust B. inner core C. outer core D. lower mantle E. asthenosphere

Answers

Answer:

The correct answer would be A. crust.

The crust is the outermost layer of the earth which is composed of different types of rocks such as sedimentary, metamorphic, and igneous rocks.

It is completely solid and can be broadly classified into two types: continental crust and oceanic crust.

The thickness of the oceanic crust is about 5 km to 10 km. It is primarily composed of basalt, gabbro, and diabase.

The thickness of the continental crust is around 30 km to 50 km.

The crust forms lithosphere along with hard and upper mantle.

What criteria would you use to assess the reproductive success of a plant?

Answers

The best way to determine this would be to determine the percentage of offspring that survived. So for example, if 900 offspring survived out of 1000 seeds, which is a 90% chance, then this can be considered successful or non successful in comparison to other trials.

What are the 4 types of processes that cycle matter through the biosphere give examples?

Answers

The 4 types of processes that cycle matter through the biosphere include the carbon cycle, water cycle, nitrogen cycle, and phosphorous cycle.

For example, nitrogen fixation and denitrification represent two fundamental processes by which nitrogen circulates between living and non-living components of the biosphere.

Biological nitrogen fixation is a mechanism by which microorganisms are capable of converting nitrogen gas (N2) to ammonia (NH3).

Denitrification refers to the bacterial process of reducing nitrate and nitrite to nitrous oxide and nitrogen, which are released as gases into the atmosphere.

In conclusion, the 4 types of processes that cycle matter through the biosphere include the carbon cycle, water cycle, nitrogen cycle, and phosphorous cycle.

Varicose veins seen in the superficial veins of the legs are unsightly and are often treated by surgical removal. However, even without these veins being present, the return of all blood toward the heart from the legs is not diminished. This is primarily because ______. the precapillary sphincters will contract to prevent blood from flowing toward areas where veins have been removed blood can still return via the deep veins in the absence of the venous valves (that have been removed), the blood will backflow into the capillary beds and then flow into other venules All of the listed responses are correct.
