Which of the following statements is not a characteristic of the prokaryotes.
Prokaryotes don't have a nucleus.
Prokaryotes have a cell wall.
All of the chemical processes take place in membrane bound organelles in the cytoplasm.
Answer:
All the chemical processes take place in membrane bound organelles in the cytoplasm.
Explanation:
Use the process of elimination:
One of the main things that make a prokaryote is not having a nucleus, so that can be eliminated.
Looking at the structure of bacteria, they can have a cell wall, so this is eliminated.
Therefore, “all the chemical processes take place in membrane bound organelles in the cytoplasm” is incorrect.
Also, prokaryotes DO NOT have membrane bound organelles like mitochondria, chloroplasts, or a nucleus, so this statement would also be incorrect because of this.

Answer:
Grass
Explanation:
Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses
grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
This is because it is a living thing (performs photosynthesis and cellular respiration).
Biotic means living, all of the other choices are not living, and would therefore be abiotic factors

which high grade, foliated metamorphic rock has visible crystals?
Answer:
Gneiss
Explanation:
Gneiss forms at the highest pressures and temperatures and has crystals large enough to see with the unaided eye. Gneiss features minerals that have separated into bands of different colors. The bands of colors are what define foliation within gneiss.
Hope this helps! : )
Gneiss crystals are large enough to be seen without magnification. Gneiss has color-banded minerals. Color bands define gneiss foliation.
What is Gneiss?The metamorphic rock known as gneiss is quite common and can be found all over the world. It is produced when procedures of high temperature and high pressure metamorphism are applied to formations that are made up of rocks that are either igneous or sedimentary in nature.
Gneiss is formed at temperatures and pressures that are higher than those required to make schist. Gneiss almost always has a banded texture that is defined by alternating darker and lighter colored bands and does not have a clear cleavage. Gneiss may also lack a distinct cleavage.
Gneisses are frequently found in the crust of continental shields that formed in the distant past. Gneisses like the Acasta Gneiss are among the oldest rocks on Earth and are classified as Proterozoic.
