TCTCG and AGAGC are the perfect pair.

Option A

<h3><u>Explanation:</u></h3>

DNA is the genetic molecule of a living cell. The DNA stores genetic information of the species inside itself by means of particular pattern or sequence of nitrogen bases called as gene. The gene is comprised of the particular sequence of nitrogenous bases which are four in number - adenine, guanine, thymine and cytosine.

The nitrogen bases are present in both the strands of DNA and they have complementary relationship between them. The adenine forms hydrogen bonds with thymine and guanine pairs with cytosine.

Here the sequence of one strand is given as TCTCG. So according to the complementary pairing process, the opposite strand must have the sequence of AGAGC to maintain the structure.

Which describes a difference between a positive and negative feedback loop?
Rudik [331]

Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Explanation:

In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.
