Answer:
Organic compounds contain carbon atoms bonded to other atoms.
Explanation:
The organic compounds have as a fundamental element carbon, an element which is tetravalent because it has four covalent bonds. Carbon can form chains of variable length, thanks to that. You can also find hydrogen in those chains that's why we can say that the organic compounds are formed by hydrocarbon chains (carbon and hydrogen)
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion
Explanation:
Transport proteins generally perform two types of transport: “facilitated diffusion,” where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and “active transport,” where the cell expends energy in order to move a substance against its concentration gradient
Answer:
I think it is A Parasitic one
Explanation:
Answer:
This mechanism causes rivers to meander, or curve. ----- water
Tides and currents from this mechanism will transfer sediments to beaches across the world. ------- waves
This mechanism causes mass wasting and landslides. ------ gravity
These slow- moving, frozen bodies transfer large boulders and sediment to areas quite far from their original locations.------- glaciers
Lack of vegetation means that this mechanism will become the dominant force for erosion and deposition.------- wind
Explanation:
Waves are responsible for the displacement and transportation of sediments in the world. The landslides occurs due to the gravitational force of earth. The big mass bodies on the sloppy areas comes to lower regions due to gravity. On the barren land, there is high chances of erosion due to wind due to no vegetative cover. These winds also carry sediments from one place to another.
