The organ in the human body that can best be compared to the mitochondria in the cell is the digestive system.

<h3>What is mitochondria?</h3>

The mitochondria is the organelle found in the living cell that helps in the generation of the cell energy. This, it is also called the powerhouse of the cell.

The mitochondria has the ability to turn the energy gotten from food into the energy the body can use.

This can be likened to the digestive system because the digestive system has the ability to breakdown food particles into the form the body can use for energy.

Why do most leaves tend to appear green if they reflect green light?

Alex73 [517]

Because our eyes see what's reflected not absorbed. Leaves contain chlorophyll which contains a pigment of green that absorbs red and blue wavelengths, while reflecting green.

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.

Explanation:

The correct answer would be ethnicity.

By definition, ethnicity refers to the variety of physical and behavioral characteristics that distinguishes one group of people from another group of people.

Individuals or a group of people that shares the same culture and a sense of identity would belong to the same ethnic group while those with dissimilar culture and physical identity would be in different ethnic group.

Why would a pea plant that is heterozygous for the tallness trait have the dominant phenotype?

AleksandrR [38]

Answer:

Dominant character is expressed in both the condition i.e. heterozygous and homozygous.

Explanation:

In genetic the dominant allele is signified by capital letter and the allele which is recessive is signified by the smaller letter. The dominant character can be expressed in both the condition that is homozygous dominant(TT) or heterozygous dominant(Tt).

Therefore even the presence of a single allele of dominant character in the gene, the dominant character can mask or suppress the recessive trait from being appeared in the phenotype. Therefore pea plant that is heterozygous for the tallness trait have the dominant phenotype.
