The following that is a characteristic that could be applied to both living and nonliving things can contain mostly carbon, hydrogen, oxygen, and nitrogen.
When you are constructing graph the independent variable always goes on the x-axis. Which is horizontally drawn.
Answer:
The correct option is <em><u>C. Foods that travel great distances cost less than foods bought locally.</u></em>
Explanation:
According to the scientific method of research, it gets initiated with a scientific question. To answer that question, a hypothesis is drawn. A hypothesis is a tentative statement based on which experiments are designed to check the authenticity of the hypothesis. Based on the observations and experiments, conclusions are drawn.
In the above-mentioned question, option C is a tentative statement that can be tested. Hence, it is the correct option.
From mouth/nose, the air passes to the trachea (the wind pipe), there it enters (sequentially) the bronchi, bronchioles (small pipe-like structures), alveoli (widened empty sacs), the walls of which are in close contact with the blood vessels which contain the RBCs, which in turn contain the protein--hemoglobin, which binds to the oxygen present in the freshly inhaled air, and loses the carbondioide present DISSOLVED in the blood. This bound oxygen goes to the heart (of course along with the RBCs in the blood), from there to the smaller and smaller arteries, then to the capillaries, where again oxygen is lost to the surrounding tissue fluid, from where the cells collect oxygen by simple diffusion, and lose carbon dioxide, which gets dissolved in the water present in the blood.
From here the blood, with hemoglobin poorer in oxygen, and richer again in carbondioxide goes to the venules, and veins (capillaries continue as venules), which become successively larger to become superior and inferior vena cava and enter the right atrium, and then from there the blood again goes to the lungs and comes in contact with fresh air in the alveoli.
Answer:
65
Explanation:
The DNA segment has a total 95 cytosine bases. Since cytosine makes hydrogen bonds with guanine base, this means that the DNA segment has a total 95 guanine bases.
Total guanine + cytosine bases in the segment= 95 + 95 = 190
So, a total of adenine and thymine bases in the DNA segment= 320-190 = 130
Since the number of adenine and thymine bases are equal in a double-stranded DNA molecule, the number of adenine bases in the given segment would be= 130/2= 65
