How is osmosis different from diffusion

1 answer:

7 0

Diffusion is a spontaneous process in which molecules move with their concentration gradient. For example, if you place food coloring in water, the food coloring will slowly diffuse through the water until the entire solution has been balanced.

Osmosis is specifically the movement of water through a semipermeable membrane - meaning a membrane that can let some substances in but keep others out - and, similar to diffusion, it moves with its concentration gradient. For example, if you place a glucose solution sealed in plastic in water, water will move into the plastic to even out the concentration of glucose in the entire solution because glucose is too large to diffuse freely.

Hope this helped!

Why would an animal cell burst if it is surrounded by fresh water?

amm1812

If an animal cell is surrounded by fresh water, the water will move within the cell causing the cell to become turgid and eventually will burst.

Therefore the most suitable answer is option D.

If a car is traveling 100 km/h west and comes to a stop in 3 min, what is the car's acceleration?

Nataly [62]

Answer:

0.15 m/s² east

Explanation:

We can use following kinematic equation for Uniformly-Accelerated Motion to solve this problem:

Where v is the final velocity, v₀ is the initial velocity, a is the acceleration and t is the time interval.

The data of the problem is:

v₀ = - 100km/h (remember to have a frame of reference, I decided traveling west will be towards the negative values and traveling east will be positive).
v = 0 km/h (the car comes to a full stop)
t = 3 min

Replacing the data in the formula:

0 km/h = -100 km/h + a × 3 min

It's very important to use the same units when solving problems. I will convert kilometer to meters and hour or minutes to seconds, because the answer choices are given in m/s².

0 km/h = 0 m/s

$\frac{100 \ km}{\ \ h} * \frac{1000\ m}{1\ km} * \frac{1\ \ h}{3600\ s} = \frac{27.78\ m}{\ \ \ \ s}$
$3 min * \frac{60\ s}{1\ m} = 180 s$

Then:

$0 m/s = -27.78 \ m/s + a * 180 s\\+27.78 m/s = a * 180 s\\$

$\frac{+27.78 \ m/s}{180\ s} = a\\\\+ 0.15 m/s^2 = a$

And considering our frame of reference, a positive sign indicates that the acceleration is east-bound.

Answer:

Stanley Miller created an experiment where he sent an electrical charge through a flask of a chemical solution of methane, ammonia, hydrogen and water . This created organic compounds including amino acids .

What makes sponges unique among animals?

Cerrena [4.2K]

They are similar in the sense that they are multicellular , lack cell walls , and produce sperm cells. However they are unique as they lack true tissues and organs and have no body symmetry.

The horizontal transfer process known as transduction ___________

Bess [88]

Answer:

involves a virus

Explanation:

Transduction is the process where DNA molecules are transferred from one bacterium to another using viruses as vectors (bacteriophages). These, when assembled within the bacteria, may eventually include pieces of DNA from the host bacteria. By infecting another bacterium, the virus that carries the bacterial DNA transfers it along with yours. If the bacterium survives viral infection, it may include the genes of another bacterium in its genome.
