Answer:

Active transport

Explanation:

Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.

The constant, dynamic process of continual addition of new bone tissue (bone ____________ ) and removal of old bone tissue (bone

elixir [45]

Answer:

(Bone deposition),

(Bone resorption),

Remodeling

Periosteal ,

Nedosteal,

The compact bone,

Spongy bone.

Explanation:

The constant, dynamic process of continual addition of new bone tissue (bone deposition) and removal of old bone tissue (bone resorption) is a process called bone remodeling. This ongoing process occurs at both the periosteal (outer) and nedosteal (inner) surfaces of a bone.

It is estimated that about nedosteal of the adult human skeleton is replaced yearly. This process does not occur at the same rate everywhere in the skeleton. For example, the compact bone in our skeleton is replaced at a slower rate than the spongy bone.

Accumulation flooding occurs because the ground is completely _____ and there is no longer a zone of _______.

maw [93]

Answer:

Accumulation flooding occurs because the ground is completely filled with water and there is no longer a zone of dry land.

Explanation:

Flood is the overflow of water on the land which is usually dry throughout the year. It occurs when more water comes in the river due to rainfall or breaking of dam. But mostly flood occurs, due to melting of ice on the poles because of global warming. Global warming refers to the increase in average temperature due to presence of greenhouse gases such as carbondioxode, methane and water vapors etc in the atmosphere.
