A gene
is something that is passed onto you, pretty much like this: My dad had blonde hair and green eyes, and that's what I got. My mom was Brown haired and blue eyes. I got her eyebrows and mouth. Get what im saying? It's something that is passed down to you.
Answer:
Respiratory disease high above the national average.
Explanation:
Particulate pollution also known as particulate matter is a mixture of liquid and solid droplets that is suspended in the air. These particles include dust, dirt, soot, smoke, and liquid droplets.
Particulate matter is derived from cars, factories, construction sites, unpaved roads, and also burning of wood and fossil fuels.
Particulate pollution have harmful effects on the human body. It could lead to respiratory symptoms such as irritation of the airways, coughing or difficulty breathing.
Yes! True. then it is followed by the other cancer.
Answer:
Animals - Plants - Energy
Plants gain energy through photosynthesis, which is then eaten by animals, which gets eaten by animals, etc.
Then, Animals die, and the energy is passed on to the soil, which passes to the plant.
Answer:
With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).
Explanation:
The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:
- <em>Adenine is complemented with Thymine A=T</em>
- <em>Guanine is complemented with Cytosine G=C</em>
From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:
<em> A + C = G + T</em>
An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:
<em> A + C = G + T</em>
<em> 5 + 7 = 7 + 5</em>
