Answer:

a. Naked dna

f. nucleosome

e. solenoid

g. loop domain

d. chromatid

c. chromosomes

b. metaphase

Explanation:

The naked DNA consists of the DNA molecule not associated with proteins.

A nucleosome is an octamer of histone proteins (i.e., dimers of H2A, H2B, H3, H4) associated with DNA.

A solenoid is a chromatin fiber consisting of 30 nanometers (nm), it represents the secondary structure of the chromatin.

The chromatin fibers are organized into loops (300 nm) that represent the tertiary structure of the chromatin. These loops enable to package chromosome segments consisting of about 100 kilobases (kb).

The sister chromatids are two identical DNA-based structures that remain joined together by the centromere to form a single chromosome (700 nm).

Some species of penguins, such as chinstrap penguins, depend on open water for their survival. Other species of penguins, such as Adélie penguins, depend on ice. Over the last 20 years, the population size of chinstrap penguins has increased, and the population size of Adélie penguins has decreased. An increase in global air and water temperatures likely caused <span>these changes in population size.</span>
