both archaea and eukaryotes possess histone proteins that complex with dna.
a. both archaea and eukaryotes contain a nucleus that separates the dna from other cellular contents.
b. both archaea and eukaryotes exist as primarily unicellular organisms.
c. both archaea and eukaryotes have multiple, linear chromosomes.
d. both archaea and eukaryotes have circular chromosomes.

Both archaea and eukaryotes possess histone proteins that complex with DNA.

Explanation:

The domain Archaea includes the prokaryotes mostly found in extreme climatic conditions such as hot springs, hydrothermal vents, etc.

The archaeans are prokaryotes like bacteria and do not have membrane-bound organelles and nucleus. However, like eukaryotes, the archaeans have histone proteins.

Histone proteins are the DNA packaging proteins present in eukaryotes. Histones make scaffold to pack the long chains on DNA into chromatin. The presence of histone proteins makes the archaeans similar to the eukaryotes.

then that particular organisms become extinct.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
