Answer:
Lungs and Endoskeleton.
Explanation:
Gills helps it live in water, and Scaly skin doesn't really apply
Genetic engineering because the genes of the plants were modified
Answer:
A= 20%
G= 30%
T= 20%
C= 30%
Explanation:
Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.
So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.
Now, A + T + C + G = 100%
So, if Adenine makes up 20% of the DNA nucleotides, Thymine is also 20%.
Then, 20% + 20% + C + G = 100%
40% + C + G = 100%
C + G = 100% - 40% = 60%
So, divide 60% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 30%
Finally, A= 20%; G= 30%; T= 20%; C= 30%
According to the research, the correct option is Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.
<h3>What is the
hydrological cycle?</h3>
It is the water cycle that allows water to pass from the earth's surface to the atmosphere so that it can then return to its liquid and solid phases. .
In this process, therefore, sublimation, evaporation and transpiration play an essential role where 70% of the earth's surface is covered by liquid water, of which 97% is salt water that forms the oceans.
Therefore, we can conclude that according to the research, the correct option is Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.
