The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

<h3 /><h3>What is a random mutation?</h3>

Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.

Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

The sodium amytal test involves the injection of a small amount of sodium amytal into the carotid artery on one side of the neck
romanna [79]

The sodium amytal test involves the injection of a small amount of sodium amytal into the carotid artery on one side of the neck. This injection anesthetizes the hemisphere on that side for a few minutes.

A method that involves injecting a small amount of a barbiturate into the carotid artery on one side of the head to assess hemispheric functions, usually memory and language. The cerebral hemisphere that was injected selectively becomes impaired for 10 to 15 minutes during this operation.

Various cognitive tests are given while each hemisphere is seperately anaesthetized; deficiencies on these tasks imply that these functions are represented in the anaesthetized hemisphere. Prior to a temporal lobectomy, the Wada test may be utilised in cases with severe and uncontrollable epilepsy. Also known as the Wada technique, intracarotid sodium Amytal test (ISA), Wada dominance test, and intracarotid amobarbital procedure.

grigory [225]

Answer:

Charles Darwin

Explanation:

Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.

In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.
