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) <span>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: </span>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 <em>twice </em>(because of stretch to the Sun and back, thus, <em>two directions</em>) of distance from <span>Earth to the Sun (ES) and :
Ratio: </span>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}
<span>      ⇒ R = 0.6677* 10^{3}
</span><span>      ⇒ [tex]R = 667.7
</span>Thus, 667,7 times will the <span>total DNA from the average human stretch from Earth to the Sun and back.</span>

Using the terms DNA, trait, code, pattern, gene, describe why each organism is unique
Rom4ik [11]
Each organism is unique because of genetic variation. Each set of genes we inherit from our parents codes for a specific trait. And our DNA is a blueprint for these traits. Not everybody contains the same genes and that is why we are all so beautifully unique.

Maria and her brother like to go fishing at the lake on Saturdays. They wondered if fish were more likely to bite at one time of
kobusy [5.1K]

Answer:

No. They will need to repeat their experiment several times, since the weather and times were different both days.

Explanation:

When a scientific experiment is conducted, one independent variable shall be changed in each experiment at a time so that the results of the experiment are authentic and we can easily determine which independent variable caused a change in the dependent variable.

If more than one independent variable is changed in the same experiment, then it will be difficult to interpret that which variable caused the change.

<u><em>Similarly, Maria and her brother need to repeat their experiment several times with just changing one variable at a time. </em></u>

Question 4 (1 point) If 18 grams of oxygen reacts completely with 4 grams of hydrogen, we would expect how many grams of water?
Lisa [10]

Answer:

C.22 grams because mass cannot be created or destroyed

Explanation:

Reaction equation:

        2H₂  +   O₂    →   2 H₂O

Mass of oxygen  = 18g

Mass of hydrogen  = 4g

The mass of water produced is 22g according to law of conservation of mass.

The law states that " in a chemical reaction, mass is always conserved"

 The sum of the mass of product  and reactants must always be the same.
