Apply your knowledge of probability to explain why a drop of food coloring in a glass of clear water spreads out so that all of

the water has an even color after some time. Determine whether after the food coloring spreads evenly in a glass of clear water it could condense back to an original droplet.

Answer:

Explanation:[14/12, 12:09 pm] Samson Tutor: There are many factors that will cause the spread of color

1) Kinetic theory of particles(Brownian motion)

2) Gravitational force acting on the colored substance

3) Density....since their density varies

Etc

[14/12, 12:10 pm] Samson Tutor: For 1) there is constant collision between the particles of the liquid and the water(especially in an haphazard motion) hence there will be transfer of momentum between the particles of the colored liquid and water.

The steps of fracture repair include:

  • Hematoma formation.
  • Fibrocartilage Callus Formation.
  • Bony Callus Formation.
  • Bone remodeling.

<h3>What is a fracture?</h3>

A fracture is a complete or partial break in a bone. The causes of bone fractures include trauma, overuse, and diseases that weaken bones.

In this case, Kyndall was lucky because the fracture occurred about 3 inches below the epiphyseal plate as this means the fracture does not break through the bone at the growth plate.

An improperly treated growth plate fracture could result in a fractured bone.

Lastly, the type of fracture is a nondisplaced fracture is one in which the bone cracks or breaks but retains its proper alignment.

Describe why the kidneys are essential for maintaining homeostasis?
gavmur [86]
Kidneys are important in homeostasis as they control the blood water level and the regulation of salt and iron contents within the body. See related links for more info.

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton
-BARSIC- [3]

Answer:

The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".

Explanation:

0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:

A: 3.21% (m/v) NaCl Solution  = crenation (higher than 0.9% (m/v) NaCl)

B: 1.65% (m/v) glucose Solution  = hemolysis (lower than 5.0% (m/v) glucose)

C: distilled H2O Solution  = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)

D: 6.97% (m/v) glucose Solution  = crenation (higher than 5.0% (m/v) glucose)

E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)

What role do proteins play in enabling the enormous amount of dna in a eukaryotic cell?
MAVERICK [17]
DNA is condensed by a certain amount just on its own, just by its own interactions within the DNA molecule,..but whne proteins get involved it gets condensed 30000 fold 
<span>what happens is that proteins called histones are like hockey pucks, and DNA wraps around it 1.5 times and then goes to another histone and wraps around that so that it looks like beads on a string (i hope that makes sense, its the only way to describe it) </span>
<span>these histones condense this DNA a lot, and when the histones get methylated then the DNA packs together even closer to get heterochromatin (VERY densely packed DNA)...the theory here is that DNA has a net negative charge due to the phosphate groups in the DNA backbone and doesnt allow the DNA to come together as closely as it could (like charges repel like charges), but when histones are methylated, the negative charge on the DNA is masked by the methyl groups and DNA can come together closer </span>
