Boron, as the only metalloid in group 13, exhibits a combination of metallic and non-metallic characteristics, while the other elements in the same group are purely metals.
A mutation involving a single base change in the DNA sequence is termed a point mutation.
Explanation:
Question 2 isn't fully provided.
3. A mutation influencing just a single nucleotide of nucleic acid is known as a Point Mutation.
In point mutations, one base substitutes for another.
For example: TAT TGG CTA
TAC TGG CTA
This shows that TAT is replaced with TAC, indicating a point mutation.
4. Yes. The point mutation has noticeable effects on the resultant sequence in comparison with the original sequence.
A change in one base in the gene can lead to diseases such as cancer or sickle cell anemia.
Atoms form molecules when they satisfy their outer electron shell by engaging in electron sharing.

Answer:
Based on the provided data, the six goldfish are placed in aquariums of varying sizes to assess how living space impacts their survival rates. The food type and quantity, sanitary conditions, and water temperature are kept consistent across the board.
Consequently, from this information, one can conclude that:
A. The independent variable is the aquarium size.
B. The number of fish remaining after six months represents the dependent variable.
C. Water temperature, food type and quantity, upkeep, and cleanliness are the controlled variables or constants.
Controlled experiments include both dependent and independent variables. The independent variable is usually the one that is altered and compared against a stable control. Meanwhile, the dependent variable, which is measured in the experiment, relies on the independent variable. The control group in an experiment is kept constant and is used for comparison with the experimental group.
