Ascientist at the polar ice cap was studying an ice sample from hundreds of meters below the surface. while examining the ice, the scientist found some cells from many years ago. using an electron microscope, the scientist identified these cell structures: a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. what kind of organism did the scientist find? a. animal
b. bacteria
c. plant
d. he did not have enough information.

C. Plant

Explanation:

Bacteria are the prokaryotic organisms and lack a well-defined nucleus. Bacteria cells also lack membrane-bound organelles such as mitochondrion. The presence of a nucleus and mitochondrion in the examined cells represents the fact that the cell is not a bacterial cell. Animal and plant cells are eukaryotic cells and have a well-defined nucleus and other membrane-bound organelles. However, an animal cell lacks a cell wall while the plant cells have cellulosic cell walls around them. This means that the examined cells are the plant cells.

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

hope this .

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
