Homeostasis is the ability of the body to preserve a steady inner environment when encountered with a changing outer condition. The statement is true.

<h3>What is homeostasis?</h3>

The condition of the constant inner environment in the body of the living organism is balanced by the process of homeostasis. It is necessary for regular body functioning.

Homeostasis is affected by many factors like water, food, pH, temperatures etc. the level of these factors are necessary to be maintained to keep the organism fit and healthy.

It is maintained by the feedback regulations and is the response to the outer varying environment. The negative feedback maintains the response to the outer changing stimuli.

Therefore, the statement is true.

You will receive a set of ten quantitative values for each of three genotypes: aa, Aa, and AA.
miskamm [114]

Mean for the <u>Geno Code 0</u> is average of those ten values ((-3.97)+(-3.99) +(-5.55)+ (-4.56) + (-4.51) + (-4.2 )+( -4.95) + (-4.56) + (-4 )+ (-5.68))/10= -4.597

Standard deviation formula is √((-3.97- (-4.597)2 )+(-3.99-(-4.597)2) +(-5.55-(-4.597)2)+ (-4.56-(-4.597)2) + (-4.51-(-4.597)2) + (-4.2-(-4.597) 2 )+( -4.95-(-4.597)2) + (-4.56-(-4.597)2) + (-4 -(-4.597)2)+ (-5.68-(-4.597)2))/10= √  (0.39+0.37+0.91+0.001+0.007+0.16+0.12+0.001+0.36+1.17)/10= √0.3489=0.59

Mean for the <u>Geno 1 </u>is -0.25 (calculated on the same way as for Geno 0 with different numbers)  and standard deviation for Geno 1 is 0.65.

Mean for <u>Geno 2</u> is 5.241 and standard deviation is 1.038.

2.

If individual Phenotype_Value is 5.11, the corresponding genotype code is Geno code 2 since the value is in the range of values 5.241+- 1.

If individual Phenotype_Value is 5.03 the corresponding genotype code is also Geno code 2.

Since the standard deviation is used to measure the variation (dispersal) of set of data values (how close the values are to the mean value) we can conclude whether are random value is within a certain range.

When thinking of the functions of the organelles.which cell tissue in the human body would have the most mitochondria and why
Anni [7]

Answer:

Muscle cells, especially heart muscle cells and fat cells have the most mitochondria in the human body.

Explanation:

Mitochondria, the powerhouse of the cell is an organelle where cellular respiration occurs. They supply energy to the cells for their functioning. The number of mitochondria in a cell vary depending on the energy requirement of that cell.

Muscle cells are very active in our body and need energy for the movement. Heart muscle cells require a lot of energy to contract and pump blood through the circulatory system all the time. So they have a lot of mitochondria to produce a vast amount of energy they need.
