Answer:

The threshold in biology is explained in terms of neuroscience or action potential that affects nervous system.

The threshold value is the value that identifies incoming signals that should be sufficient enough to generate an action potential. The potentials generated by the signals are additive, and reaches threshold depends on their amplitude and frequency.

An absolute threshold is defined as the minimum level of signals like light, touch or sound , detected by any organism and allows them to react.

While Difference threshold allow to detect difference between two different signals.

Following the rules of complementary base pairing, which of these DNA bases could successfully bond with adenine?
AURORKA [14]

Answer:

Thymine

Explanation:

Adenine is a Purines together with Guanine .

Purines always pair with Pyrimidines ; which are cyosine and Thymine.

This is a complementary base pairing that hold the two strands of DNA bases together by weak hydrogen bonds for flexibility and easily unwind during replication

Purines are larger in size beaxuae they have 2 ring structures while Pyrimidines aee smaller because of one ring structure.

Therefore two purines (Adenine and Guanine can not pair together;

It must be a Purines -Pyrimidines pairs.

Therefore Adenine must pair with Thymine and cyosine with Guanine

In RNA, Thymine are replaced with URACIL as Pyrimidines.
