Which of what? What’s the rest
This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
I think it is A because they can just destroy it but D is finding something natural to kill it off but it is GM so it wouldn't help so A
Answer:
DNA
Explanation:
<h2>What is DNA?</h2>
DNA is a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
When SA Node triggers Atria goes into Systole !! and when the signal reaches to AV node and from there it goes to Bundle of His making Ventricle to systole or constrict !!
So your answer is Systole !!
