Answer:
The model of the DNA can be related to a zipper. Just like the zipper, the two strands of the DNA are joined together by the hydrogen bonds present between the nucleotides. At the time of replication, the coiling of the two strands is undone just as the zipper is open. The two strands of the DNA open and separate just as the two stands of the zipper open and separate. Each strand can give rise to anew strand.
Just as the opening and closing of the zipper can cause damages in the zipper, just like this replication can cause errors in the DNA which lead to mutations.
It can be found in Mid-Altantic Ridge. The alternating magnetic stripes in the basaltic bedrock is an evidence of sea floor spreading. The lines in the basaltic rocks, follow whichever is the magnetic field on Earth during the time of eruption.
Bored* lol and being bored sucksss. What’s up
This depends on the point of view, I believe. Chelicerate is not the direct ancestor of trilobites, but it is related but distantly.
Answer:
The correct answer will be option-E.
Explanation:
The nervous system is one of the most important systems of the animal body which helps in the transmission of the signals to and fro from the body to the nervous system.
The evolution of this system is the basis of the evolution of the human species as it helped and tried the species to sense the external environment most efficiently as well as improved the response to the environment.
The nervous system improved the response by forming new interactions with each other and responding to it by reducing the response time through reflex actions which formed fast acting response to the environment. The transmission of signals improved as the cells were long-lasting that is present form the birth of an organism
Thus, option-E is the correct answer.
