Answer:

linker DNA

Explanation:

the classic beads on a string structure is termed as the nucleosome; which is the most basic level of chromosome packaging. the nucleosome is made up of 2 molecules each of the four histone proteins (H2A, H2B, H3, H4) to form an octamer around which a length of DNA is wrapped. linkage of this nucleosome to another nucleosome is done by a length of linker DNA and a linker histone (H1). thus experimentally to produce this structure, the linker DNA between two nucleosomes is degraded by nucleases to extract the structure. thus the linker DNA is not retained after the experiment.

7. Slime molds are fungus like protists, but they are not fungi. Why?
MrMuchimi

Answer:

Because they can move

Explanation:

Fungi cannot make food themselves so they depend heavily on hosts. Also fungi lack the proper cilia to move, so they use spores instead to "move".

In the case of slime mold, they are like an animal fungus per se. They are like Protozoa in their amoeboid plasmodial stage and similar to true fungi in spore formation.

Marsupial mole rats evolved in New Zealand in the 1700s and had few natural predators so they overpopulated the area. Scientist
r-ruslan [8.4K]

Answer:

C. Some marsupial mole rats had a natural immunity to the virus.

Explanation:

According to Darwin's evolutionary theory, over time some of marsupial moles may have acquired natural immunity which evolves as an adaptive trait in the population. Since these organisms have more chance to survive and reproduce (survival of the fittest), they will likely transmit the natural immunity to the next generation .
