Plzzz....someone ....Diffusion

Taya2010 [7]

The meaning of diffusion is the movement of the molecules reign from high concentration to a low concentration reign. As a result, there is a random motion between the atoms and molecules.
Hope this helps :)

The number of cells in an average-sized adult human is on the order of 10^14 cells. Use this information, and the estimate that

KengaRu [80]

IF:
Number of cells: $C = 10^{14}$
DNA lenght: $D = 2m = 12.42 * 10^{-4} mi$
Distance from Earth to Sun: $ES=93000000 mi = 9.3* 10^{7}mi$

Then:
a) Over how many miles would the total DNA from the average human stretch?
The answer is product of multiplication of the number of cells (C) and the DNA length (D):
Total DNA: $T = C*D$
⇒ $T = 10^{14}*12.42* 10^{-4} mi$
⇒ $T = 12.42* 10^{14-4} mi$
⇒ $T = 12.42* 10^{10} mi$
The total DNA from the average human will stretch $12.42* 10^{10} mi$

b) How many times would the total DNA from the average human stretch from Earth to the Sun and back?
The answer is concluded from the ratio of the total DNA length (T) and the twice (because of stretch to the Sun and back, thus, two directions) of distance from Earth to the Sun (ES) and :
Ratio: $R= \frac{T}{2*ES}$
⇒ $R = \frac{12.42* 10^{10}mi }{2*(9.3* 10^{7}mi)}$
⇒ $R = \frac{12.42* 10^{10}}{18.6*10^{7}}$
⇒ $R = 0.6677* 10^{10-7}$
 ⇒ $R = 0.6677* 10^{3}$
 ⇒ [tex]R = 667.7
Thus, 667,7 times will the total DNA from the average human stretch from Earth to the Sun and back.

How does carbon dioxide leave the atmosphere?

Delvig [45]

Plants go through a process called photosynthesis where they take in carbon dioxide from the atmosphere (as well as water and sunlight), and they turn it into oxygen (so we can breathe) and glucose (sugar)!

This is the process of changing energy from one form to another. Solar energy is changed into chemical energy by plants.

Colt1911 [192]

Answer:

Energy Transformation

Explanation:

The conversion of energy from one from to another is known as energy transformation.

Energy can only be converted or transferred from one object to another or to a different location but it can never be created from scratch. A good example is given in the question that solar energy is converted into chemical energy with the help of plants.

I hope the answer is helpful.

Thanks for asking.

What are the labels of the transmission electronic microscope image of a chloroplast

Nina [5.8K]

Answer:

Explanation:

Transfer RNA (tRNA) precursors undergo endoribonucleolytic processing of their 5' and 3' ends. 5' cleavage of the precursor transcript is performed by ribonuclease P (RNase P). While in most organisms RNase P is a ribonucleoprotein that harbors a catalytically active RNA component, human mitochondria and the chloroplasts (plastids) and mitochondria
