Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.

Explanation:
The osmotic gradient in the kidney typically in the medulla is a process that generates urine that is 5 times more concentrated so as to reduce the loss of water from the body.
The countercurrent multiplication is a process that uses energy to produce the osmotic gradient in the kidney, this process facilitates the reabsorption of water from the tubular fluid. This mechanism moves the sodium chloride from the tubular fluid to the interstitial space of the kidneys. The osmotic gradient can be developed in two ways:
1. The single effect: This involves the transport of sodium chloride from the tubular fluid and moved to the ascending limb then finally to the interstitial fluid. As a result of this, the water moves passively down to the concentration gradient out of the tubular fluid than to the descending limb of the interstitial space, until the equilibrium is achieved.
2. Fluid flow method: The tubular fluid enters into the descending limb. This pushes the fluid into high osmolarity typically down the tube. This way the osmotic gradient develops.
Answer:
"ABCDE" features:
Asymmetry - asymmetric (½ does not match the other ½)
Border - the border is slightly irregular
Color - a mixture of colors including a very dark brown area
Diameter - the mole was new and greatly increased in size over just 6 months
Evolving - this new mole had changed in size, color, and shape during a very short period of time
