Resultant force = mass × acceleration, therefore acceleration = resultant force ÷ mass
Resultant force = 19 - 1.7 = 17.3 N
acceleration = 17.3÷2= 8.65 ms-2
Difference threshold is a minimum alteration in sensory intensity that is noticeable to an observer and can be coded into neural messages. Different threshold is the lowest level of encouragement that is essential to sense that a modification has happened the difference in the intensity between two stimuli that is necessary to yield a just notable difference also known as JND. The just notable difference depends not only on the intensity of the new stimulus but also on the level of stimulation already present which is the more intense the existing stimulus the larger the change must be to be noticeable.
Nucleotides lining up along the template strand according to base pairing rules process helps to preserve the genetic information stored in DNA during DNA replication
Option D
<h3><u>Explanation:</u></h3>
The DNA is a semi conservative molecule from the genetic information storing point of view. The genetic information is stored there in form of the alignment and arrangement of the nitrogen bases. These nitrogen bases are replicated just in order to conserve the genetic information.
During protein synthesis, same nitrogen bases get denoted in the RNAs and this gives the particular protein which is required in the body. No molecule present in the body can destroy the DNA and its alignment. It’s conserved as long as no external molecule or force destroys it. So it’s conserved in a very safe way.
