Answer:
Explanation:
In this lesson we will learn the three basic parts of all cells. Cells have something called a cell membrane, a nucleus, and cytoplasm.
IF:
Number of cells:

DNA lenght:

Distance from Earth to Sun:

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>

⇒

⇒

⇒
The total DNA from the average human will stretch 
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>

⇒

⇒

⇒

<span> ⇒

</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>
Answer:
<h2>a. 1000 X 2^8</h2>
Explanation:
As given;
Initial population of bacteria= 1000;
Log phase growth is exponential phase, period in which bacteria gets double.
Generation time= 15 minutes;
it means, bacteria get double in every 15 minute,
so after 2 hours, bacteria will have 8 generation times;
so the final generation of bacteria is =1000 X 2^8.
Final bacterial generation after two hours = 256,000(1000 X 2^8)
Answer:
Bones
Explanation:
Bones are tissues that provide the body with rigidity. It also acts as the body's supporting structure.
The bone helps to maintain the body's shape at all times and provide a surface for the attachment of muscles. Joints are the points of contact between two bones. The bones, muscles and joints are very important in the locomotion(movement) process because there’s a synergy between them.
<em><u>The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor. </u></em>
Explanation:
MC1R’s function-This receptor plays an important role in normal pigmentation. The receptor is primarily located on the surface of melanocytes, which are specialized cells that produce a pigment called melanin.
