Observation is the only option that is not a variable in scientific experiment.
<h3>
What are variables in scientific experiment?</h3>
Variables are factors, or condition that can exist in differing amounts during a scientific experiment.
<h3>Types of variables in scientific experiment</h3>
Scientific experiment usually has three kinds of variables:
- independent,
- dependent, and
- controlled.
Thus, Observation is the only option that is not a variable in scientific experiment.
The complete question is below:

Answer : The percentage of food gives an idea about the food availability for the species of organisms. If the food percentage is high the species is observed to be more successful; on the other hand if the percentage is low the species is found to shrink in numbers. The numbers of particular species is directly proportional to the percentage of food. Also, it shows the options of other food resources on the basis of their availability.
Answer:
Early geneticists wondered how only four nucleotides could specify the sequence of 20 amino acids in proteins. Today we know that there is a genetic code in which <u>3</u> nucleotide(s) code(s) for each amino acid.
Explanation:
64 or 43 is the number of possible 3-letter codes which is more than the number of amino acids. Hence, the code can thus be redundant. It has been seen that there is more than one codon that codes for the same amino acid in some cases, .

<span>#1) How does attachment affect exploration?
Answer: According to Ainsworth attachment acts as a form of secure base, which is used by the infant to explore the rest of the world and make further attachments. This was concluded after noticing that during strange situation children are more than likely to explore the setting in presence of the mother than the stranger. Harlow studied attachment of monkeys, which makes both investigations highly different.
