As you can see in the picture presented below, the three classes of water have distinctive traits.
Pure substances contain only one element, they are not mixtures of different things.
The homogeneous mixtures have multiple elements, but they are so well blended together that you can't easily observe or separate them.
In heterogeneous mixtures, we can easily differentiate between different elements of the mixture.

Classify each statement based on whether it describes prokaryotes only, eukaryotes only, or can describe both prokaryotes and eu

Phantasy [73]

Answer:

unicellular - both prokaryotes and eukaryotes

contain mitochondrion - eukaryotes only

are generally less than 2 pm - Prokaryotes only

multicellular - eukaryotes only

lack membrane-bound organelles - prokaryotes only

Explanation:

Prokaryotes are generally unicellular, that is, they are made up of single cells only. However, there are unicellular and multicellular eukaryotes with some eukaryotes like humans and advanced plants having as many as millions of cells.

Prokaryotes generally lack nucleus and other membrane-bound organelles such as chloroplast and mitochondrion. Eukaryotes on the other hand have nucleus and membrane-bound organelles such as mitochondrion and chloroplast.

When it comes to size, prokaryotes are generally small and microscopic while eukaryotes consist of both microscopic and macroscopic cells or organisms. However, prokaryotes are generally smaller than microscopic eukaryotes.

Describe the relative locations of the following bacterial cell components:

Dovator [93]

Answer:

A. outside plasma membrane:

1. cell wall 6. flagella

B. outside of the cell

4. fimbriae 5. pilus

C. in cytoplasm

2. nucleoid 3. ribosome

Explanation:

Bacteria is one of the three domains of cellular organisms. Bacteria are prokaryotes, cells that lack a true nucleus and membrane-bound organelle.

The plasma membrane is the outer membrane that enclosed the cytoplasm and cytoplasmic substance. The cell wall is covering the present out of the cell membrane or plasma membrane. Flagella are attached to the plasma membrane but it is present outside of the plasma membrane.

Fimbriae and pilus are the structure present outside of the cell wall and help to attach it to other cells or any surface. Nucleoid and ribosomes are present in the cytoplasm of the bacterial cell.
