Answer:
harmful farming practices is the use of inorganic fertilizers.
Explanation:
these kinds of fertilizers promise a lot in terms of the cultivation and growth of the plants in your farm. However, because of the harmful substances used in making these inorganic fertilizers, they might cause adverse effects to people and to the other plants. This is because some ingredients used in these fertilizers are considered toxic. This might even kill other plants, animals and harm people who have accidentally gotten exposed to these components.
Answer:
28% Thymine
Explanation:
DNA molecule is made up of four nucleotides namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These nucleotides make up the DNA molecule unevenly, however, according to Chargaff in his rule, he stated that the amount of Adenine&Thymine, Guanine& Cytosine in a DNA must be equal, which must all equate to 100% i.e. (A = T) + (G = C) = 100%
Based on this Chargaff's rule, if a DNA sample is analyzed and found to contain 22% of cytosine. This means that the amount of Guanine in that DNA sample must also be 22%.
Therefore; 22% C + 22% G = 44%
100 - 44 = 56%. This means that Adenine and Thymine will share this 56% among each other i.e. 56/2 = 28% Adenine and 28% Thymine.

So i believe C is the correct answer :)
