Answer: The correct answer is A) A+C=G+T
According to Watson and Crick base pairing-
In a double stranded DNA molecule, Adenine pairs with Thymine and Guanine pairs with Cytosine. This means that number of Adenine in one strand is equal to the number of thymine in the complementary DNA strand. Similarly, the number of Cytosine in one strand is equal to the number of Guanine in the complementary strand.
Thus, the total number of Adenine and Cytosine in one strand becomes equal to the total number of Guanine and Thymine in the complementary strand.
This can be mathematically written as- A+C = G+T
Thus, option A) is the right answer.
I believe the answer is C. E. And F.
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
Answer:
B. stomata.
Explanation:
Stomata are openings in the surface of the plant epidermis through which gases and water vapor pass. They are formed by two elongated cells whose shape is similar to bean grain or dumbbell depending on the species. These cells are called guard cells, and in their midst there is a slit called the ostiole.
The stomata make the exchanges between the external and internal environment of the plant. They regulate the size of the opening, so it is possible to increase or decrease the rate of perspiration of the plant.
Stomata are usually located at the bottom of the leaf, but in aquatic plants such as the water lily they are at the top and still in vertical growing plants on both sides.
Answer:
Energetic coupling of chemical processes in metabolic pathways Biochemical systems couple energetically unfavorable reactions with energetically favorable reactions. These reactions can be part of catabolic pathways where complex substances are broken into simpler ones with the release of energy or anabolic pathways where complex molecules are synthesized with an input of energy.
