Answer:
The correct answer is- olfactory nerve(1)
Explanation:
Olfactory nerve is the first nerve out of the 12 cranial nerve that is located in the head and is also the shortest of all the cranial nerve. The receptors of the olfactory nerve are present in the nasal mucosa that passes to the forebrain.
It pass sensory information of smell to the brain so it plays the sensory function in smell perception. The damage to olfactory nerves can lead to:
Anosmia: In anosmia, people lose their ability to smell.
Hyposmia: In this condition, the ability to smell gets reduced.
Dysosmia: In this situation, people lost their ability to distinguish between various types of smell.
So the right answer is olfactory nerve(1).
Answer: A double restriction digest
Explanation: A double restriction digest is a process were two restriction enzymes are used to digest DNA in a single reaction.in double restriction digest you will observe two bands,while in single restriction digest you will observe just one band. In double restriction digest no
Self - ligating plasmid because it create mismatch ends. It also aids in directional in section while single disgestion you have to screen your clones to be sure to get your plasmid with correct insert orientation.
The reason why a dichotomous key to identify organism is valuable, is because it helps you classify organisms,it helps you identify eco -systems, it helps you analyze an organism's traits.
Explanation:
A dichotomous key is a skill that has been brought about by scientists, to help people to identify and classify organisms.
In Dichotomous key, the main way of identifying an object is by it scientific name.This is because, though two objects might look similar to each other but they might belong to a whole different species.
So, it is is easier to identify the organism from its scientific name, as it will tell us which species it belongs to.
This key is very useful to people who are novice, and don't know much about identifying an organism.
This key also helps identifying, whether an organism belongs to a particular closely related group of organisms or is a separate organism.
It helps one analyze the traits of an organism, and based on their characteristics, it will help you identify and classify the species of the object or organism.
