Answer:
<em>B. Nucleus </em>
Explanation:
<em>DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA</em>. <em>Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). </em><em>Mitochondria are structures within cells that convert the energy from food into a form that cells can use.</em>
<em>The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people</em>
There are many different ways to solve this. If you are a visual learner, see the image of the normal distribution graph attached. This shows the empirical rule of
68-95-99.7 which means that approximately 68 % of the data is within 1 standard deviation, 95% of the data is within 2 standard deviations, and 99.7 % of the data is within 3 standard deviations.
In this case,
the mean is 3 and the since the
standard deviation given is 0.25, we are going to have a the center of the graph the number 3 because the mean given is 3 minutes. We move one space to the right and that would represent 3.25 minutes, one more space to the right and that is
3.50 minutes. Similarly, go back to the center of the graph, which we decided would be 3 because it is the mean. Now move one space to the left, this would be 2.75, one more space to the left and this represents
2.50 minutes.
The questions asks to approximately what percent of red lights last
between 2.5 and 3.5 minutes. Notice 2.5 and 3.5 fall within 2 standard deviations, and we previously said that 95% of the data is within 2 standard deviations. Therefore, the percent of red lights that last between 2.5 and 3.5 minutes is
95%
Answer:
One disadvantage of having a large surface area to volume ratio is the heat loss. An organism that has larger surface area has high rate heat gain and heat loss. Therefore they need to eat or acquire nutrients faster in order to sustain life.

Answer:
B. Phenotypes
Explanation:
Genotypes is genetic makeup of organism (like the actual genes for particular trait). Phenotype is the expression of that genotype and is usually a physical trait. My best guess is B for this question.
